THE HOT WATER OIL EXPULSION TECHNIQUE FOR GEOTHERMAL RESOURCES : A SUGGESTION FOR BATI RAMAN OILFIELD OF TURKEY

Alperen Şahinoğlu

Abstract

With the rapid development of Turkey?s petroleum industry, oil production, the way of burning crude oil to produce steam, need to change. Heavy oil reservoir with thin layer or edge water is unsuitable for thermal recovery. Electric heating leads to considerable electrical consumption. Low injection water temperature decreases reservoir temperature and increased crude oil viscosity. The prolonged temperature difference break up reservoir pore throat cement and framework minerals. To improve high-capacity channel communication, we proposed geothermal oil recovery. Broad-sense abundant geothermal resources and existing injection water technique equipment are used. Deep-seated high temperature liquid (oil-gas-water mixture) draws geothermal warming flowing layer to transit heat upward, decreases viscidity and increases fluidity. Reservoir temperature offers different geothermal fountain. Practicability of the process is analysed. Statistical analyses and reservoir temperature variation analysis of Bat? Raman Oilfield, Turkish Petroleum, was made. Flow-chart concept for geothermal oil recovery has been designed to suggest drilling multi-branch well in heavy oil reservoir. While drilling an injection-well, at the same position of geothermal fountain well, using free-pressure pump to inject hot liquid directly to aimed oil layer, made oil recovery in surrounding wells. We proposed that geothermal oil recovery forerunner test should be first conducted in favourable blocks.
