(A West Virginia Limited Partnership)



Notes to Financial Statements

(Unaudited)





1.	Accounting Policies



Reference is hereby made to the Partnership's Annual Report on Form 10-K for 2003, which contains a summary of significant accounting policies followed by the Partnership in the preparation of its financial statements.  These policies were also followed in preparing the quarterly report included herein.



2.	Basis of Presentation



The Management of the Partnership believes that all adjustments (consisting of only normal recurring accruals) necessary to a fair statement of the results of such periods have been made.  The results of operations for the six months ended June 30, 2004 are not necessarily indicative of the results to be expected for the full year.



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 which will be determined at year end by an independent petroleum engineer, Wright & Company, Inc.  If a determination is made that an exploratory well has not discovered economically producible reserves, then its costs are expensed as dry hole costs.



4.	Revenue Recognition



Sales of oil and natural gas are recognized when the rights and responsibilities of ownership pass to the purchaser and are net of royalties.



5.	Derivative Instruments and Hedging Activities



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 production. These instruments consist of costless collars and option contracts traded on the CIG (Colorado Interstate Gas Index).  The costless collars and option contracts hedge committed and anticipated natural gas sales generally forecasted to occur within a 24 month period. The Managing General Partner does not hold or issue derivatives for trading or speculative purposes.

6.     New Accounting Standards



A reporting issue has arisen regarding the application of certain provisions of SFAS No. 141 and SFAS No. 142 to companies in the extractive industries, including oil and gas companies. The issue is whether SFAS No. 142 requires registrants to classify the costs of mineral rights (leases) associated with extracting oil and gas intangible assets in the balance sheets, apart from other capitalized oil and gas property costs, and provide specific footnote disclosures. Historically, the Partnership has included the costs of mineral rights associated with extracting oil and gas as a component of oil and gas properties. If it is ultimately determined that SFAS No. 142 requires oil and gas companies to classify costs of mineral rights associated with extracting oil and gas as a

(Unaudited)





separate intangible assets line item on the balance sheet, the Partnership would be required to reclassify the historical cost of approximately $219,125 of mineral rights associated with developed oil and gas properties as of June 30, 2004 and December 31, 2003 out of oil and gas properties and into a separate intangible mineral rights assets line item. The Partnership's total balance sheet, cash flows and results of operations would not be affected since such intangible assets would continue to be amortized and assessed for impairment.  There is a proposed FASB staff position issued that clarifies that reclassification will not be necessary under the exception to SFAS No. 142 but the comment period is still open.  Final resolution is expected by the end of the Partnership's third quarter.



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



Liquidity and Capital Resources



The Partnership was funded on September 3, 2003 with initial Limited and Additional General Partner contributions of $17,345,901 and the Managing General Partner's cash contribution of $3,772,733 in accordance with the Agreement.  After payment of syndication costs of $1,821,320 and a one-time management fee to the Managing General Partner of $433,438 the Partnership had available cash of $18,863,666 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, 2003.  Twenty-six wells have been drilled, all of which have been completed as producing wells.   No additional wells will be drilled.



The Partnership had net working capital at June 30, 2004 of $1,307,187.



Operations are expected to be conducted with available funds and revenues generated from oil and gas activities.  No bank borrowings are anticipated.

Results of Operations

Three months ended March 31, 2004

Oil and gas sales for the three months ended June 30, 2004 were $1,525,070.  For the three months ended June 30, 2004, the Partnership sold 230,694 Mcf of gas and 14,456 barrels of oil at average prices of $4.62 and $31.84, respectively.  The Lifting cost per Mcfe for the three months ended June 30, 2004 amounted to $.71.    While the Partnership experienced a net income of $651,895, depreciation, depletion and amortization is a non-cash expense and therefore the Partnership distributed $1,590,242 to the partners for the three months ended June 30, 2004.

Six months ended June 30, 2004

Oil and gas sales for the six months ended June 30, 2004 were $3,671,758.  For the six months ended June 30, 2004, the Partnership sold 451,268 Mcf of gas and 46,379 barrels of oil at average prices of $4.61 and $34.31, respectively.  The Lifting cost per Mcfe in the first six months of 2004 amounted to $.64.  While the Partnership experienced a net income of $1,717,220, depreciation, depletion and amortization is a non-cash expense and therefore the Partnership distributed $2,753,935 to the partners for the six months ended June 30, 2004.



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 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 Partnership's financial condition and results of operations and require management's most subjective or complex judgments.  The policies are as follows:



Revenue Recognition.  Sales of natural gas are recognized when the rights and responsibilities of ownership pass to the purchasers and are net of royalties.



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.



Depreciation, Depletion and Amortization



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



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



The judgments used in applying the above policies are based on management's evaluation of the relevant facts and circumstances as of the date of the financial statements. Actual results may differ from those estimates. See additional discussions in this Management's Discussion and Analysis.

Item 3.	Quantitative and Qualitative Disclosure About Market Rate 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



Natural gas and oil prices have been unusually volatile for the past few years, and the Partnership anticipates continued volatility in the future.  Currently, the NYMEX futures reflect a market expectation of gas prices at Henry Hub close to or above record prices per million Btu's (mmbtu). The CIG price index has historically ranged from 80% to 90% of the NYMEX price.  These prices look strong for 2004 although natural gas storage levels are near normal levels following a period when storage levels had been at a five-year low. The Partnership believes this situation creates the possibility of both periods of low prices and continued high prices.



Because of the uncertainty surrounding natural gas prices the Managing General Partner used hedging agreements to manage some of the impact of fluctuations in prices for the Managing General Partner and its various limited partnership's share of production. Through October of 2005 the Partnership has in place a series of costless collars and option contracts. Under the collar arrangements, if the applicable index rises above the ceiling price, the Partnership pays the counterparty, however if the index drops below the floor the counterparty pays the Partnership. For the period from April 2004 through October 2004, the Partnership has floors in place in a range from $3.20 to $4.17 on 20,647 Mmbtu of monthly production and ceilings in place at $4.70 on 10,323 Mmbtu of monthly production.

PDC 2003-B LIMITED PARTNERSHIP

Notes to Financial Statements

(Unaudited)







Open option contracts maturing in the next twelve months are for the sales of 103,234 Mmbtu of natural gas with an average ceiling price of $5.17 and for the sale of 206,467 Mmbtu of natural gas with an average floor price of $4.11 and a fair value of $(120,396).  The maximum term over which the Partnership is hedging exposure to variability of cash

flows for commodity price risk is 16 months.  For the period from November 2004 through March 2005, the Partnership has floors in place at $5.04 on 16,517 Mmbtu of monthly production and ceilings in place at $6.00 on 8,259 Mmbtu of monthly production.  For the period April 2005 through October 2005, the Partnership has floors in place at $3.10 on 13,764 Mmbtu of monthly production and ceilings in place at $4.43 on 6,882 Mmbtu of monthly production. As of June 30, 2004 the Partnership had total option contracts for the sale of 130,763 Mmbtu of natural gas with an average ceiling price of $5.01 and for the sale of 261,525 Mmbtu of natural gas with an average floor price of $3.90.  The fair value of these floors and ceilings on natural gas as of June 30, 2004 is $(58,920).



As of June 30, 2004 the Partnership had total open oil future contracts on 19,326 barrels of oil with a total contract amount of $611,291 and a fair value of $(106,327).  All of the oil future contracts mature within the next twelve months.



Disclosure of Limitations



As the information above incorporates only those exposures that exist at June 30, 2004, 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-14(c)) 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 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.
