Analysis of results the use hydraulic fracturing modeling on Kome oil field in the republic of Chad
Results of the analysis of geological and physical characteristics and indicators of the Kome development oil field in the republic of Chad. The following characteristics were confirmed: highly permeable reservoirs, heavy oil, high temperatures. Operations to increase the productivity index of this field have been a conducted for seven years. This work is based on the use of different applications of hydraulic fracturing. The efficiency of the fracturing depends on the amount of fluids. It also depends the fluid-sand carrier (proppant); precisely on its concentration, on its sequence of entry into the cracks and finally on the rate of injection process during the hydraulic fracturing. A block diagram of the choice of hydraulic fracturing technology has been proposed. The most effective TSO hydraulic fracturing has been identified. Moreover, it has been noted that the most effective fluid-sand carriers for hydraulic fracturing are the water-based, time adjustable gels. For this reason, we recommend research on enhancing hydraufrac TSO technology be oriented to the experimental study of process liquids and to the modeling of key parameters which take into account the minimum values of leaks in the reservoir rock.
