Successful field evaluation of the efficiency of a gas gravity drainage proces by applying recent developments in sponge coring technique in a major oil field

摘要

This paper describes the application and integration of new technologies and recent developments in Sponge coring and presents the methodology used to carry out successfully the various phases of well designed Sponge coring project, including the coring phase, the on-site measurements and the full evaluationof the Sponge core samples. A field case is presented where a Sponge coring project was accomplished to obtain accurate fluids distribution and evalute the gas gravity drainage efficiency in one of the Arab D sub-reservoirs of a major oil field offshore Abu Dhabi.
