Assessment of applicability of preformed particle gels for Perm region oil fields

Abstract

The application of preformed particle gels (PPG) in Russian oil fields is very limited. In this research the authors tried to find tools for primary screening of oil wells candidates for PPG application. For a fractured reservoir, the Warren-Rutt method was considered for estimating fracture sizes in injected oil wells. Taking into account the mechanical properties of the developed PPG, a powder fraction is recommended for starting treatment of oil wells. An express method for assessing the pressure index (PI) was considered for the primary selection of well candidates. PI provides information on reservoir heterogeneity. Using this method, the most promising candidates for the implementation of PPG technology were selected.
