New Solutions for Well Test Analysis of Horizontal Wells

摘要: Horizontal wells are becoming popular for primary and enhanced oil recovery operations because of unique advantages horizontal in comparison to those vertical wells. For example, being used, at present, the heavy worldwide. They allow a larger reservoir exposure, which increases productivity, accelerate recovery, reduce coning tendencies. However, well testing is considerably more complex than testing. This work addresses new solutions test analysis With similar methods Ref. [1,2,3], taking as uniform line sink three dimensional space, by developing necessary mathematical analysis, this paper presents pressure drawdown buildup analyses single porosity with circular cylinder drainage volume. The obtained here based on models accurate two model equations literature. Simplified short long times that exhibit straight-line sections when plotted vs. time presented. Methods analyzing build-up data method allows characteristics, including permeability, skin be determined.
