Evolution of a Hybrid Fracture/Gravel-Pack Completion: Monopod Platform, Trading Bay Field, Cook Inlet, Alaska (SPE 19401)

Summary

In Australia, post-frac PTA and production data analysis indicated that future treatments should be designed to further increase fracture conductivity, despite the use of 20/40 sand and 16/20 HSP tail-ins.

Abstract

Some low permeability reservoirs in Central Australia require successful hydraulic fracture stimulation of production and injection wells to enable economic development. The techniques available to determine the created fracture properties include post-fracture pressure transient analysis and production post-fracture pressure transient analysis and production performance history matching. The results of such evaluation performance history matching. The results of such evaluation will indicate the design changes required for optimum future treatment efficiency.

The methodology of detailed well test analysis for a number of fractured weds in an oil reservoir is described. Type curves and specialized plots for individual flow regimes are used in the analysis. Post-fracture pressure transient behaviour for these wells is generally bilinear flow dominated. The analysis results are validated by production history matching and indicate that future cumulative production for most wells in this reservoir could be further increased by improvements in created fracture conductivity.
