Notes to Financial Statements

(Unaudited)

1. Accounting Policies

The accompanying condensed interim financial statements and related disclosures are unaudited and have been prepared pursuant to U.S. generally accepted accounting principles for interim financial statements and the rules and regulations of the Securities and Exchange Commission (the Commission). As permitted by these regulations, certain information and footnote disclosures that would typically be required in annual financial statements have been condensed or omitted. However, management believes that these statements reflect all the normal recurring adjustments necessary for a fair presentation, in all material respects, of the results of operations for the periods presented, so that these interim financial statements are not misleading. These condensed financial statements should be read in conjunction with the financial statements and notes thereto included in the PDC 2000-B Limited Partnership's (the Partnership) Annual Report on Form 10-K for the year ended December 31, 2004.

2. Use of Estimates

To prepare financial statements in accordance with generally accepted accounting principles, the Partnership's management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements, and reported amounts of revenues and expenses incurred during the reporting period. Actual results could differ from those estimates.

3. Oil and Gas Properties

The Partnership follows the successful efforts method of accounting for the cost of exploring for and developing oil and gas reserves. Under this method, costs of development wells, including equipment and intangible drilling costs related to both producing wells and developmental dry holes, and successful exploratory wells are capitalized and amortized on an annual basis to operations by the units-of-production method using estimated proved developed reserves determined at year end by Petroleum Development Corporation's (the Managing General Partner's) petroleum engineers. If a determination is made that an exploratory well has not discovered economically producible reserves, then its costs are expensed as dry hole cost.

The Partnership assesses impairment of capitalized costs of proved oil and gas properties by comparing net capitalized costs to undiscounted future net cash flows on a field-by-field basis using expected prices. Prices utilized in each year's calculation for measurement purposes and expected costs are held constant throughout the estimated life of the properties. If net capitalized cost exceeds undiscounted future net cash flow, the measurement of impairment is based on estimated fair value which would consider future discounted cash flows.

4. Revenue Recognition

Sales of natural gas are recognized when natural gas has been delivered to a custody transfer point, persuasive evidence of a sales arrangement exists, the rights and responsibility of ownership pass to the purchaser upon delivery, collection of revenue from the sale is reasonably assured and the sales price is fixed or determinable. Natural gas is sold by the Managing General Partner under contracts with terms ranging from one month to three years. Virtually all of the Managing General Partner's contracts pricing provisions are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality of natural gas and prevailing supply and demand conditions, so that the price of the natural gas fluctuates to remain competitive with other available natural gas supplies. As a result, the Partnership's revenues from the sale of natural gas will suffer if market prices decline and benefit if they increase. The Partnership believes that the pricing provisions of its natural gas contracts are customary in the industry.

PDC 2000-B LIMITED PARTNERSHIP

(A West Virginia Limited Partnership)

Notes to Financial Statements

(Unaudited)

The Managing General Partner currently uses the "Net-Back" method of accounting for transportation arrangements of natural gas sales. The Managing General Partner sells gas at the wellhead and collects a price and recognizes revenues based on the wellhead sales price since transportation costs downstream of the wellhead are incurred by the Managing General Partner's customers and reflected in the wellhead price.

Sales of oil are recognized when persuasive evidence of a sales arrangement exists, the oil is verified as produced and is delivered in a stock tank, collection of revenue from the sale is reasonably assured and the sales price is determinable. The Partnership is currently able to sell all the oil that it can produce under existing sales contracts with petroleum refiners and marketers. The Partnership does not refine any of its oil production. The Partnership's crude oil production is sold to purchasers at or near the Partnership's wells under short-term purchase contracts at prices and in accordance with arrangements that are customary in the oil industry.

5. Derivative Financial Instruments

The Managing General Partner utilizes commodity based derivative instruments as hedges to manage a portion of the Partnership's exposure to price volatility stemming from natural gas and oil production. These instruments consist of CIG (Colorado Interstate Gas Index) based contracts for Colorado production, and NYMEX (New York Mercantile Exchange) traded oil futures and option contracts for Colorado oil production. The costless collars and option contracts hedge committed and anticipated oil and natural gas sales generally forecasted to occur within a 24 month period. The Partnership does not hold or issue derivatives for trading or speculative purposes.

All derivatives are recognized on the Partnership's balance sheet at their fair value. On the date the derivative contract is entered into, the Managing General Partner designates the derivative as a hedge of a forecasted transaction (future production and sales of oil and gas) ("cash flow" hedge), or a non-hedging derivative. The Managing General Partner formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash-flow hedges to specific firm commitments. The Managing General Partner also formally assesses, both at the hedge's inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. When it is determined that a derivative is not highly effective as a hedge or that it has ceased to be a highly effective hedge, the Partnership discontinues hedge accounting prospectively. No hedging activities were discontinued during 2005 or 2004.

Changes in fair value of a derivative that is highly effective and that is designated and qualifies as a cash-flow hedge are recorded in accumulated other comprehensive income, until earnings are affected by the variability in cash flows of the designated hedged item. Changes in the fair value of non-hedging derivatives are reported in current-period earnings. The Partnership discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is sold, terminated, or exercised. Additionally, if the derivative is designated as a hedging instrument, because it is probable that a forecasted transaction will not occur, or the Partnership determines that designation of the derivative as a hedging instrument is no longer appropriate, hedge accounting will be discontinued.

By using derivative financial instruments to hedge exposures to changes in commodity prices, the Managing General Partner exposes the Partnership to credit risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Partnership, which creates credit risk. The Managing General Partner minimizes the credit risk in derivative instruments by entering into transactions with high-quality counterparties.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

Liquidity and Capital Resources

The Partnership was funded on September 30, 2000 with initial Limited and Additional General Partner contributions of $11,602,809 (580.14 units) and the Managing General Partner's cash contribution of $2,523,611 in accordance with the Limited Partnership Agreement. After payment of syndication costs of $1,218,295 and a one-time management fee to the Managing General Partner of $290,070 the Partnership had available cash of $12,618,055 for Partnership activities.

The Partnership began exploration and development activities subsequent to the funding of the Partnership and completed well drilling activities by December 31, 2001. Twenty-seven wells have been drilled, all of which have been completed as producing wells. No additional wells will be drilled.

The Partnership had working capital at June 30, 2005 of $410,902.

Operations are expected to be conducted with available funds and revenues generated from oil and gas activities. Under the Limited Partnership Agreement, the Partnership is not permitted to borrow funds.

Results of Operations

Three months ended June 30, 2005 compared with June 30, 2004

Oil and gas sales for the three months ended June 30, 2005 were $481,551 compared to $427,486 for the three months ended June 30, 2004, an increase of $54,065 or 12.6%. The volume of natural gas sold for the three months ended June 30, 2005, was 56,665 Mcf at an average sales price of $6.19 per Mcf compared to 57,794 Mcf at an average price of $4.87 per Mcf for the three months ended June 30, 2004. The volume of oil sold for the three months ended June 30, 2005 was 2,739 barrels at an average sales price of $47.77 compared to 4,245 barrels at an average price of $34.34 for the three months ended June 30, 2004. The lifting cost for the three months ended June 30, 2005 was $1.93 per Mcfe compared to $1.23 per Mcfe for the three months ended June 30, 2004. This increase is partially attributed to the increase in severance and property taxes along with costs associated with workovers. The fixed costs of operations and well maintenance are allocated to lower production volumes, therefore increasing the lifting cost per Mcfe. Depreciation, depletion and amortization for the three months ended June 30, 2005 was $151,454 compared to $152,294 for the three months ended June 30, 2004. The Partnership experienced a net income of $186,379 and $173,189 and distributed $241,572 and $306,149 to the partners for the three months ended June 30, 2005 and 2004, respectively.

Six Months ended June 30, 2005 compared with June 30, 2004

Oil and gas sales for the six months ended June 30, 2005 were $865,232 compared to $813,541 for the six months ended June 30, 2004, an increase of $51,691 or 6.4%. The volume of natural gas sold for the six months ended June 30, 2005, was 101,455 Mcf at an average sales price of $5.95 per Mcf compared to 110,800 Mcf at an average price of $4.98 per Mcf for the six months ended June 30, 2004. The volume of oil sold for the six months ended June 30, 2005 was 5,697 barrels at an average sales price of $45.97 compared to 7,624 barrels at an average price of $34.34 for the six months ended June 30, 2004. The lifting cost for the six months ended June 30, 2005 was $1.80 per Mcfe compared to $1.41 per Mcfe for the six months ended June 30, 2004. The increase is partially attributed to the increase in severance and property taxes along with costs associated with workovers. The fixed costs of operations and well maintenance are allocated to lower production volumes therefore increasing the lifting cost per Mcfe. Depreciation, depletion and amortization for the six months ended June 30, 2005 was $274,609 compared to $287,639 for the six months ended June 30, 2004. The Partnership experienced a net income of $343,906 and $305,829 and distributed $558,194 and $573,210 to the partners for the six months ended June 30, 2005 and 2004, respectively.

Notes to Financial Statements

(Unaudited)

The Partnership's revenue from oil and gas will be affected by changes in prices. As a result of changes in federal regulations, gas prices are highly dependent on the balance between supply and demand. The Partnership's oil and gas sales prices are subject to increase and decrease based on various market sensitive indices.

Critical Accounting Policies

Certain accounting policies are very important to the portrayal of the Partnership's financial condition and results of operations and require management's most subjective or complex judgments. In applying those policies, our management uses its judgment to determine the appropriate assumptions to be used in the determination of certain estimates. Those estimates are based on our historical experience, our observance of trends in the industry, and information available from other outside sources, as appropriate. The Partnership's critical accounting policies and estimates are as follows:

Revenue Recognition. Sales of natural gas are recognized when natural gas has been delivered to a custody transfer point, persuasive evidence of a sales arrangement exists, the rights and responsibility of ownership pass to the purchaser upon delivery, collection of revenue from the sale is reasonably assured and the sales price is fixed or determinable. Natural gas is sold by the Managing General Partner under contracts with terms ranging from one month to three years. Virtually all of the Managing General Partner's contracts pricing provisions are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality of natural gas and prevailing supply and demand conditions, so that the price of the natural gas fluctuates to remain competitive with other available natural gas supplies. As a result, the Partnership's revenues from the sale of natural gas will suffer if market prices decline and benefit if they increase. The Partnership believes that the pricing provisions of its natural gas contracts are customary in the industry.

of natural gas sales. The Managing General Partner sells gas at the wellhead and collects a price and recognizes revenues based on the wellhead sales price since transportation costs downstream of the wellhead are incurred by the Managing General Partner's customers and reflected in the wellhead price.

Impairment of Long-Lived Assets The Partnership assesses impairment of capitalized costs of proved oil and gas properties by comparing net capitalized costs to undiscounted future cash flows on a field-by-field basis using expected prices. Prices utilized in each year's calculation for measurement purposes and expected costs are held constant throughout the life of the properties. If net capitalized costs exceed undiscounted future net cash flow, the measurement of impairment is based on estimated fair value which would consider future discounted cash flows.

Oil and Gas Properties

Exploration and development costs are accounted for by the successful efforts method.

Property acquisition costs are capitalized when incurred. Geological and geophysical costs and delay rentals are expensed as incurred. The costs of drilling exploratory wells are capitalized pending determination of whether the wells have discovered economically producible reserves. If reserves are not discovered, such costs are expensed as dry holes. Development costs, including equipment and intangible drilling costs related to both producing wells and developmental dry holes are capitalized.

Unproved properties and leases are written-off to expense when it is determined that they will expire to be abandoned.

Costs of proved properties, including leasehold acquisitions, exploration and development costs and equipment, are depreciated and depleted by the unit-of-production method based on estimated proved developed oil and gas reserves.

Upon sale or retirement of complete fields of depreciable or depletable property, the book value thereof, less proceeds or salvage value, is credited or charged to income. Upon sale of a partial unit of property, the proceeds are credited to accumulated depreciation and depletion.

Recently Issued Accounting Pronouncements

Asset Retirement Obligations

On March 30, 2005, the FASB issued FASB Interpretation No. 47, "Accounting for Conditional Asset Retirement Obligations" (FIN No. 47). This interpretation clarifies that the term "conditional asset retirement obligation" as used in Statement No. 143 refers to a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity incurring the obligation. The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and/or method of settlement. Thus, the timing and/or method of settlement may be conditional on a future event. Accordingly, an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated. Uncertainty about the timing and/or method of settlement of a conditional asset retirement obligation should be factored into the measurement of the liability, rather than the timing of recognition of the liability, when sufficient information exists. FIN No. 47 will be effective for the Partnership at the end of the fiscal year ended December 31, 2005. The Partnership has not yet determined the final impact on the Partnership's financial position or results of operations of the application of FIN No. 47, however the Partnership does expect to record an unfavorable cumulative effect of change in accounting principle within the statement of operations before year end. Such effect may be material to the financial statements.

Disclosure Regarding Forward Looking Statements

This Form 10-Q contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). All statements other than statements of historical facts included in and incorporated by reference into this Form 10-Q are forward-looking statements. These forward-looking statements are subject to certain risks, trends and uncertainties that could cause actual results to differ materially from those projected. Among those risks, trends and uncertainties are the Managing General Partner's estimate of the sufficiency of its existing capital sources, its ability to raise additional capital to fund cash requirements for future operations, the uncertainties involved in estimating quantities of proved oil and natural gas reserves, in prospect development and property acquisitions and in projecting future rates of production, the timing of development expenditures and drilling of wells, and the operating hazards attendant to the oil and gas business. In particular, careful consideration should be given to cautionary statements made in the various reports the Partnership has filed with the Securities and Exchange Commission. The Partnership undertakes no duty to update or revise these forward-looking statements.

When used in the Form 10-Q, the words, "expect," "anticipate," "intend," "plan," "believe," "seek," "estimate" and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Because these forward-looking statements involve risks and uncertainties, actual results could differ materially from those expressed or implied by these forward-looking statements for a number of important reasons, including those discussed under "Management's Discussions and Analysis of Financial Condition and Results of Operations" and elsewhere in this Form 10-Q.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

Market-Sensitive Instruments and Risk Management

The Partnership's primary market risk exposure is commodity price risk. This exposure is discussed in detail below:

Commodity Price Risk

The Managing General Partner utilizes commodity-based derivative instruments as hedges to manage a portion of its exposure to price risk from its oil and natural gas sales. These instruments consist of NYMEX-traded natural gas futures contracts and option contracts for Michigan production, and CIG-based contracts traded by JP Morgan for Colorado production. These hedging arrangements have the effect of locking in for specified periods (at predetermined prices or ranges of prices) the prices the Managing General Partner will receive for the volume to which the hedge relates. As a result, while these hedging arrangements are structured to reduce Partnership's exposure to changes in price associated with the hedged commodity, they also limit the benefit the Partnership might otherwise have received from price changes associated with the hedged commodity. The Partnership's policy prohibits the use of oil and natural gas future and option contracts for speculative purposes.

Disclosure of Limitations

As the information above incorporates only those exposures that exist at June 30, 2005, it does not consider those exposures or positions which could arise after that date. As a result, the Partnership's ultimate realized gain or loss with respect to commodity price fluctuations will depend on the exposures that arise during the period, the Partnership's hedging strategies at the time and commodity prices at the time.

Item 4. Controls and Procedures

Under the supervision and with the participation of the Managing General Partner's management, including the Managing General Partner's Chief Executive Officer and Chief Financial Officer, the Managing General Partner has evaluated the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Exchange

Act Rule 13a-15(e)) as of the end of this fiscal quarter, and, based on their evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that these disclosure controls and procedures are effective in all material respects, including those to ensure that information required to be disclosed in reports filed or submitted under the Securities Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the Commission's rules and forms, and is accumulated and communicated to management, including the Managing General Partner's Chief Executive Officer and Chief Financial Officer, as appropriate to allow for timely disclosure. There have been no significant changes in our internal control over financial reporting or in other factors that have materially affected or are reasonably likely to materially affect these controls that occurred during the Partnership's last fiscal quarter and subsequent to the date of their evaluation.
