... a slight increment in ΔP and relatively stable across 60 PV. Discussions Development of a successful improved recovery technique after a reservoir is flooded with water (secondary recovery) will hugely depend on the outcome of waterflood implementation. It is imperative that the mechanisms...

... Abstract This paper focuses on using a timeseries neural network to forecast the oil recovery of a mature oil reservoir undergoing tertiary CO 2 water alternating gas (WAG) enhanced oil recovery (EOR). Estimating future oil recovery is a necessity for planning an effective EOR strategy...

... Abstract Low permeability rock usually holds a large amount of residual oil after flooding. The two most important mechanisms for residual oil recovery are interfacial tension (IFT) reduction and wettability alteration (WA). There is confusion around the coupled effect between the two...

... Abstract Accurate modeling of CO 2 /CH 4 competitive adsorption behavior is a critical aspect of enhanced gas recovery associated with CO 2 sequestration in organic-rich shales (CO 2 -ESGR). It not only improves the ultimate recovery of shale gas reservoirs that satisfies the increasing...

... In this study, the recovery characteristic of a heavy crude oil from Edward County, Texas, USA was tested through steam and solvent-steam injection methods. Physical properties of initial oil sample is reported in Table 1 . Accordingly, this crude is a heavy oil since the API gravity is between...

... effects, and we delve into the characteristic behavior of oil during primary production and pressure depletion. Following the depletion, we will discuss the nature of the residual oil in the organic material and discuss how to enhance the recovery using ethane (C 2 H 6 ) and comparing that recovery...

... was found to be the most sensitive variable when maximizing gas recovery. 3 ABSTRACT The Sterling B4 sands is a reservoir underlain by an aquifer located on the Kenai Peninsula of Alaska. This dry gas-on-water reservoir, holding approximately 13.9 billion cubic feet (Bcf), has experienced...

..., high oil-price differentials and well costs have made it difficult for drilling to remain profitable. The core of the DJ basin (Wattenberg) has one of the lowest break-even prices in the region, and rig count continues to increase as operators start seeing signs of recovery in the market. The Uinta...

... Abstract Recovery of bypassed oil banked against non-conductive faults in heavily-faulted and stress-sensitive reservoirs such as the Wilmington and Kern River fields of California can raise concerns of fault destabilization. Here, we investigate the effects of well configuration and well flow...

... simulation with CrunchFlow Multicomponent Reactive Flow and Transport Software. For core saturated with high viscosity oil (Core2), flooding with HS water at 25°C resulted in an ultimate oil recovery (UOR) of 48% OOIP, and flooding low viscosity oil core (Core1) with HS water resulted in a similar UOR of 50...

... Abstract In this study, a novel technique of low salinity hot water (LSHW) injection with addition of nanoparticles has been developed to examine the synergistic effects of thermal energy, low salinity water (LSW) flooding, and nanoparticles for enhancing heavy oil recovery, while optimizing...

... Abstract It is difficult to produce oil from diatomite due to unique rock properties such as low permeability, high porosity, fine laminations, and fractures. Steam injection is a promising enhanced oil recovery method for diatomite, but the generation and injection of steam may lead to large...

Accordingly, this paper reviews the evidence for and against three doctrines in current use to develop depletion plans: (i) optimal recovery is obtained using a voidage replacement ratio (VRR) of 1, (ii) the Buckley-Leverett formulation...

... Abstract Steam injection is the most successful oil recovery method for heavy oil and oil sands exploitation. In some cases, solvents are added to steam when steam by itself fails to provide satisfactory recovery factors. In other instances, the use of solvents is justified on the basis...
