This paper presents the simulation results of field development optimization of low permeability carbonate reservoirs containing high viscous oil by the system of horizontal wells. The wells are located in special way to take into account the geological features of this field, the water injection at certain moments of time and all potential water breakthroughs from the WOC area. Multivariant reservoir simulation runs were performed in order to identify the optimal well density, the optimal length of horizontal sec...

This paper discusses the method of increasing the recovery rate when developing deposits of terrigenous sediments at a late stage by involving inactive wells into the field development using sidetracks covering undrained areas. In order to estimate the predicted flow rates of wells with horizontal sidetracks, calculations were carried out for seven wells using four analytical methods for wells which are in the pressure observation well stock, suspended well stock, inactive due to the reaching limit by water cut an...

This paper describes the results of the project which uses information from core lab studies in reservoir simulation in order to improve the quality of the forecasting ability. Samples of core were selected for each of the rock type in order to study wettability. Studies on the determination of the contact angle of wetting were carried out by the device, which allows determining the surface tension and contact angle in the formation conditions. The obtained values were applied for each of the five rock types for f...
