Primary recovery factor as a function of production rate: implications for conventional reservoirs with different drive mechanisms

Abstract

This study evaluates the dependency of production rate on the recovery of hydrocarbon from conventional reservoirs using MBAL simulator. The results indicated that the recoveries are sensitive to the production rate in almost all hydrocarbon reservoirs. It was also found that the recovery of volumetric gas drive reservoirs is not impacted by the production rate. In fact, any increase in the production rate improves gas recovery in weak and strong water drive reservoirs. Moreover, increasing the production rate in oil reservoirs decreases the recovery with a significant effect observed in the weak water drive reservoirs. The results of this study demonstrate the need for implementing an effective reservoir management in order to obtain a maximum recovery.

Spatial and temporal distribution of hydrocarbon production on the UK continental shelf

“…Rates of depletion in the form of maximum field rate and average cumulative monthly production are relatively low. This is because rates of depletion are deliberately slowed and managed in line with predetermined maximum efficient rates of depletion to avoid lower ultimate recovery at the end of field life (Bruce, 1976; Posner, 1972; Raza et al, 2019; Sukubo & Obi, 2018).…”

Stability and Rheological Properties of the Hydroxypropyl Methyl Cellulose-Based Graft Copolymer/Halocynthia roretzi Drasche-Based Cellulose Nanocrystal/Sodium Dodecyl Sulfate Dispersion for Enhanced Heavy Oil Recovery

“…In recent years, the supply and demand of petroleum have entered an unbalanced state with continuous oil exploitation and utilization. , Tertiary oil recovery technology (enhanced oil recovery) improves oil recovery significantly by regulating the interaction between oil and various injections, including the augment of reservoir pressure, the reduction of oil viscosity, and the modification of the reservoir state. , Polymer flooding technology is one of the chemical branches of tertiary oil recovery technology, which is a kind of valid approach to improve the sweep efficiency and recovery efficiency of reservoirs, and thus can increase the viscosity of the aqueous phase, adjust the oil/water mobility ratio, and stabilize the front of displacement. , …”

Effects of injection well operation conditions on CO2 storage capacity in deep saline aquifers

“…At low rates, the liberated gas segregates at the top of the reservoir and is produced rapidly, which as a result, depletes the reservoir energy and decreases oil recovery. Raza et al 28 presented a simulation study to evaluate the dependency of hydrocarbon recovery on production rate for gas and oil reservoirs of different drive mechanisms. The authors reported that oil recovery decreases with the increase of production rate for most drive mechanisms.…”
