Rising to the Challenge – How to Successfully Perform Hydraulic Fracturing in Tectonically Stressed Conditions

J. Chavez1, N. Aamri1, and C. Zerbst1



Petroleum Development Oman LLC (PDO) has recently begun appraisal drilling and testing of a recent exploration tight gas discovery. The discovered reservoirs are in previously undrilled, deep formations, with high temperatures, unknown pressure regimes, and uncertain fluid fill and composition. The unique geological properties of this type of reservoir require different strategies and technology deployment to make them viable and sustainable.

The development of tight gas accumulations requires the use of hydraulic fractures as part of the sand face completion. In the Sultanate of Oman, fracturing under High Pressure and High Temperature (HPHT) conditions can take the implementation of this technology to its limits. The challenges are increased due to stress regime variations that are strongly influenced by tectonics in this part of the country.
