Abstract

Pluspetrol Peru Corporation took over the operation of the block 88: Camisea by December 2000. After the environmental impact assessment, the first field operation related to G&G disciplines was the acquisition of 800 km2 of 3D seismic to cover San Martin and Cashiriari structures. The objective was to improve the structural image, delineate the fluid distribution, resolve the internal bed geometry and recognize any reservoir heterogeneity. The field development contemplates the drilling of the wells from only two well pads in each structure. Consequently, these are high-angle extended-reach wells where the wellbore stability assessment has become mandatory on the preparation of the drilling program. Several proved and new technologies were applied in issues as drilling fluids, fracture and pressure gradient analysis and rock mechanical properties feeding a geomechanical model. To follow-up the well operations in such a remote area a real-time data transmission via web page was implemented. All authorized interested personnel from anywhere access all that data. The implemented welltest design resulted in a very precise tool to obtain the better performance of the well. A multi-compositional numerical simulator helps in improving recoveries and anticipates production. Several conceptual models were run to perform sensitivity analyses to different parameters and designs. Finally, with all these new technologies and concepts applied, the obtained results exceeded the expected and gave a good confidence to the future field performance. The first well San Martin-1001 was spuded on July 15th, 2002 reaching the final depth of 3002 mMD in 75 days with an offset of 1500 m. The Absolute Open Flow was estimated in 470 MMscfD of Gas.
