during the Pennsylvanian and early Permian The Spraberry Trend, which includes the Wolfcamp interval, is located in the Midland Basin of the Permian Basin It was discovered in 1948 and commenced production in 1949 It contains 40 BBO in-place in Spraberry-Dean interval − Much more oil in-place in deeper zones of Wolfcamp, Strawn, Atoka and Mississippian 12 – Spilled into main depocentre to south forming distal fans – Saddles between atoll mounds acted as conduits for clastics Spraberry formation was a mud-rich fan complex – High transport efficiencies allowed extensive network of muds,

In this presentation, Pioneer includes estimates of quantities of oil and gas using certain terms, such as “resource,” “resource potential,” “oil in place,” “EUR” or other descriptions of volumes of reserves, which terms include quantities of oil and gas that may not meet the SEC’s definitions of proved, probable and possible reserves, and which the SEC's guidelines strictly prohibit Pioneer from including in filings with the SEC. These estimates are by their nature more speculative than estimates of proved reserves and accordingly are subject to substantially greater risk of being recovered by Pioneer. U.S. investors are urged to consider closely the disclosures in the Company’s periodic filings with the SEC. Such filings are available from the Company at 5205 N. O'Connor Blvd., Suite 200, Irving, Texas 75039, Attention Investor Relations, and the Company’s website at www.pxd.com. These filings also can be obtained from the SEC by calling 1-800-SEC-0330. 50
