Well Logging Interpretation and Old Wells Review in Block X of Talala Basin

Abstract

Block x is located in the Tarala basin on the continental shelf of the northern coast of Peru. The oilfield has a production history of more than 100 years, and its structure is complex. The main reservoir belongs to clastic rock reservoir with complex fault blocks, poor reservoir physical properties, weak edge and bottom water energy, large number of wells and simple logging suite. Aiming to the current situation of the study area, the responses of well-logging on zones with low pressure are studied. This paper develops a set of batch processing program on multiple well logging evaluation for the reservoir based on Geolog software, which effectively improves the efficiency of logging data interpretation and reduces the work intensity of interpretation personnel. On the basis of detailed interpretation, this paper review the production history of the reservoir in the study area, and reperforating on return O formation were recommended according to the current situation of insufficient development of O formation for many years. The treated wells have achieved good effects on incremental oil production, and our recommendation effectively guide the productivity construction of block X.
