Field-Development Case Study: Production Optimization Through Continuous Multidisciplinary Reservoir and Production Monitoring (SPE 103987)

Summary

16/30 BoroProp did not provide the expected productivity in the Priobskoye field.  Use of larger and higher conductivity proppant is yielding higher productivity indices.

Abstract

This paper presents a field-development case study of a low-permeability turbidite reservoir in Russia. The giant Priobskoye field contains 30ºAPI crude in laminated sandstones of 0.1 to 20 md at a depth of approximately 2,500 m. The complex geology, lack of reservoir information and lack of technology availability caused a 20-year gap between discovery and development.

The initial pilot development was halted after poor drilling success, thus the operator invested in 3D-seismic acquisition and an integrated, multidisciplinary reservoir modeling and simulation effort. The subsequent development was based on oriented waterflooding patterns and massive hydraulic fracturing, together with an artificial-lift system equipped with permanent pressure and rate monitoring for evaluation and real-time production enhancement.

The optimization of operational practices and introduction of fit-for-purpose technologies enabled a production increase from an intermittent hundreds of BOPD to more than 75,000 BOPD in a period of 3.5 years. The exploitation strategy of this pilot area demonstrated commercially sustainable production from the reservoir and will form the basis for full field development.
