Exhibit 99.1 Clayton Williams Energy Announces 2006 Third Quarter Results MIDLAND, Texas--(BUSINESS WIRE)--Nov. 9, 2006--Clayton Williams Energy, Inc. (NASDAQ:CWEI) reported net income for the third quarter of 2006 of $5.3 million, or $.48 per share, as compared to a net loss of $2 million, or $.19 per share, for the third quarter of 2005. Cash flow from operations for the third quarter of 2006 was $39.4 million, as compared to $50.4 million during the same period in 2005. For the nine months ended September 30, 2006, the Company reported net income of $26.7 million, or $2.38 per share, as compared to a net loss of $1.1 million, or $.10 per share, for the same period in 2005. Cash flow from operations for the nine-month period in 2006 was $116.5 million, as compared to $126.6 million during the same period in 2005. Oil and gas sales for the third quarter of 2006 totaled $61.5 million compared to $65.7 million for the same quarter in 2005. Of the $4.2 million decrease in oil and gas sales, lower oil and gas prices accounted for a decrease of $2.2 million and lower oil and gas production volumes accounted for the remaining $2 million decrease. Oil production for the third quarter of 2006 dropped slightly to 532,000 barrels, or 5,783 barrels per day, from 537,000 barrels, or 5,837 barrels per day in the 2005 quarter. Gas production decreased 4% to 3.7 Bcf, or 40,630 Mcf per day, from 3.9 Bcf, or 42,359 Mcf per day in the 2005 quarter. Average realized oil prices in the third quarter of 2006 increased 12% from $59.95 to $67.27 per barrel, while gas prices decreased 22% from $7.98 to $6.26 per Mcf. Average realized prices for 2006 and 2005 exclude the effects of any gains or losses realized on commodity hedging transactions since those derivatives were not designated as cash flow hedges and have been reported in the Company's statements of operations as gain/loss on derivatives under applicable accounting standards. For the third quarter of 2006, the Company reported a $26.7 million net gain on derivatives, consisting of a $28.4 million non-cash gain to mark the Company's derivative positions to their fair value on September 30, 2006 and a $1.7 million charge for cash settlements during the quarter. For the same period in 2005, the Company reported a $28.8 million net loss on derivatives, consisting of a $20.8 million non-cash mark-to-market loss and an $8 million charge for cash settlements. Exploration costs related to abandonments and impairments were $19.7 million during the third quarter of 2006, of which $8.1 million was attributable to the Apache Louisiana Minerals 73-1 (Abigail) in South Louisiana, $5.9 million was attributable to two exploratory wells on the Focus Ranch unit in Colorado, $2.9 million was primarily due to acreage impairments in West Texas and $2.1 million was attributable to the Weyerhaeuser #1 (Frazier Creek) in North Louisiana. The Company's exploration costs were $13.9 million in the third quarter of 2005. The Company recorded a non-cash charge during the third quarter of 2006 of $12.9 million for an impairment of proved properties pursuant to Statement of Financial Accounting Standards No. 144 "Accounting for Impairment or Disposal of Long-Lived Assets." The impairment, which applied to two areas in West Texas and one area in South Louisiana, was required to reduce the carrying value of these proved properties to their estimated fair market value.

Notes to tables and supplemental information (a) Hedging gains (losses) are only included in the determination of the Company's average realized prices if the underlying derivative contracts are designated as cash flow hedges under applicable accounting standards. The Company did not designate any of its 2006 or 2005 derivative contracts as cash flow hedges. This means that the Company's derivatives for 2006 and 2005 have been marked-to-market through its statement of operations as other income/expense instead of through accumulated other comprehensive income on the Company's balance sheet. This also means that all realized gains/losses on these derivatives are reported in other income/loss instead of as a component of oil and gas sales. (b) The accompanying consolidated financial statements include the accounts of Larclay JV, a drilling rig joint venture formed with Lariat Services, Inc. ("Lariat") in April 2006 to own and operate twelve new drilling rigs. Although the Company and Lariat own equal interests in Larclay JV, the Company meets the definition of the primary beneficiary of Larclay JV's expected cash flows under Financial Interpretation No. 46R, "Consolidation of Variable Interest Entities - an interpretation of ARB No. 51 (as amended)" ("FIN 46R"). Accordingly, the Company is required to include the accounts of Larclay JV in the Company's consolidated financial statements. Lariat's net equity in the assets, liabilities and operations of Larclay JV are reflected as minority interest accounts in the Company's consolidated financial statements. The Company's intercompany accounts with Larclay JV have been eliminated in consolidation. (c) In May 2006, the State of Texas adopted House Bill 3, which modified the state's franchise tax structure, replacing the previous tax based on capital or earned surplus with a margin tax (the "Texas Margin Tax") effective with franchise tax reports filed on or after January 1, 2008. The Texas Margin Tax is computed by applying the applicable tax rate (1% for the Company's business sector) to the profit margin, which is generally determined by total revenue less either cost of goods sold or compensation, as applicable. Although House Bill 3 states that the Texas Margin Tax is not an income tax, the Company believes that Statement of Financial Accounting Standards No. 109 "Accounting for Income Taxes ("SFAS 109") applies to the Texas Margin Tax. Accordingly, the Company has computed its consolidated deferred tax liability based on its current interpretation of the Texas Margin Tax, resulting in a reduction of deferred tax expense during the nine months ended September 30, 2006 of $4.1 million. The Company's effective federal and state income tax rate for the nine months ended September 30, 2006 of 22.4% differed from the statutory federal rate of 35% due to reductions in the tax provision related to the adoption of the Texas Margin Tax and statutory depletion, offset in part by certain non-deductible expenses.
