Pressure Transient Analysis using Well-Head Pressures
Nathan Waldman,
Data Retrieval Corporation
Abstract:
Pressure Transient Analysis is the most important tool available to the engineer trying to characterize and manage the productivity of his reservoir. The PTA test has traditionally relied on data from down-hole pressure gauges which are expensive to run, risk tool loss in the well bore, and expose personnel to injury. Because of these factors, critical reservoir management decisions are often made without adequate PTA testing. Using surface pressures for PTA dramatically reduces costs, eliminates risk and allows frequent testing. However, pressure transient testing presents several technical challenges in conversion of surface pressure to reservoir conditions. This presentation discusses these challenges and presents examples of Pressure Transient Analysis from simultaneously acquired surface and down-hole pressures. The key idea to take away from this lecture is that it is possbile to perform non-intervention Pressure Transient Test on most naturally unloading gas wells using surface pressures.
Biography:
Nathan Waldman graduated from University of Cincinnati with a degree in Chemical Engineering. He received his Masters and Doctorate degrees in Polymer Physics at Virginia Polytechnic Institute. Waldman joined Dow Chemical Company in 1967 and worked in Research and International Business Development. Waldman left Dow in 1979 for the Presidency of Cathodic Protection Services (CPS) in Houston, Texas. While at CPS, Waldman became familiar with data acquisition procedures for Pressure Transient Analysis in oil and gas reservoirs. He recognized that this critically important technique failed tot take advantage of new computer technologies that could improve the quality and efficiency of the service. Based on that recognition, he founded Reservoir Dyanmics to introduce the latest electronic technologies to Pressure Transient Testing. Waldman then developed a process fo non-intervention reservoir testing and founded Data Retrieval Corporation to market that process which is the basis of this Distinguished Lecturer presentation.
