Research on the applicability of pumping hydrocarbon solvent- thermochemical system for single-well treatment to enhance heavy oil recovery in Lower Miocene and Upper Oligocene of Rong field
Abstract
The paper presents the research results on the applicability of pumping hydrocarbon solvent-thermochemical system for single-well treatment to increase the oil flow and enhance heavy oil recovery in the Lower Miocene and Upper Oligocene of Rong field. The hydrocarbon solvent recommended for application is liquefied petroleum gas (LPG). The thermochemical system is based on NaNO2 and NH4Cl capable of generating heat and creating pressure. Experimental simulation results on the PVT device at a temperature of 95oC and pressure varying between 100 - 300atm show that LPG drastically reduces the viscosity of the renewable crude oil of Rong field.
