Waterflood monitoring using borehole self-potential data
A cross-hole imaging technique is developed to follow the evolution of an oil-water encroachment front over time during the water flooding of an oil reservoir. I simulate borehole electric potentials associated with a two-phase flow between two wells in a heterogeneous reservoir. The flow of the …

Investigation of a three-dimensional analog model for waterflood predictions
Includes bibliographical references (pages 48-50).

Using waterflood performance to characterize flow-units in a heterogeneous reservoir
Simulation of waterflood performance is used to verify the characterization of flow-units in a heterogeneous reservoir. BOAST98 software was used for simulation of waterflood performance. Two adjacent five spot patterns in the Stringtown field in West Virginia were selected to be evaluated in this …

A streamline model application for the waterflood performance of NZ-OF-HRL carbonate reservoir
The NZ-OF-HRL Carbonate reservoir had produced only 3.07 per cent of the oil in place, mainly by internal gas drive, when the pressure had declined from the original pressure of 4,781 psig to 4,009 psig to 8,750 feet. As a result of such rapid change in pressure and due to the fact that energy …

Simultaneous Multiple Plane to Plane Waterflooding in Fractured Tight Reservoirs
Waterflooding is common in conventional reservoirs, but efforts to apply waterflooding to unconventional tight oil formations have not met much success. The purpose of this research is to investigate the effectiveness of a novel 3-well pattern using horizontal wells (one injector and two producers, …

Improvement of Carbon Dioxide EOR in Water-Wet Reservoirs by Using Active Carbonated Water
… residual oil in water-wet reservoirs. After waterflood, a slug of carbonated water is pre-flushed before CO2 flood, followed by an extended waterflood. A series of parallel tests are performed to compare the recovery efficiencies of tertiary floods. Additionally, the slug size of carbonated …

Improving the simulation of a waterflooding recovery process using artificial neural networks
The waterflood performance of the dual five-spot pilot project in the Stringtown oil field, situated in West Virginia, has been studied. A numerical simulator, called BOAST98, was used for the simulation purposes, after developing a reservoir description.;The producing horizon in the field is the …

Theoretical and experimental investigation of oil recovery by the electrothermic technique
… from a five-spot laboratory model by cold waterflood and the electrothermic technique. The experimental data were compared with the numerically calculated responses. Agreement between calculated and experimental responses supports the assumptions of the mathematical model and the numerical …

Rheology and Flow Behaviour of Non-Newtonian, Polymeric Fluids in Capillaric and Porous Media: Aspects Related to Polymer Flooding for Enchanced Recovery of Heavy Oil
… oil in place (OOIP) after primary recovery and waterflooding. Many of these fields are operated at high producing water/oil ratios (WORs) only marginally above their economic limit due to additional production, handling, and treatment expenses that can average $3/m3 of water. Depending on timing …

Finite difference modeling of oil recovery by waterflooding using horizontal well injectors
Waterflooding is the most commonly used injection method for secondary recovery of oil reservoirs. The selection of a horizontal well or a vertical well as an injector is an important issue in waterflooding because these two types of wells can behave differently due to their orientation in the …

Improved reservoir characterization by incorporating geodetic data in a western Kazakhstan oilfield
… to enhance pressure maintenance and improve waterflood effectiveness. Also, further geomechanical and InSAR comparison suggests the presence of a weak edge aquifer influx behavior in the area of study flowing north to south. In summary, the combination of reservoir simulation, geomechanical …

Application of dynamic optimization methods for foam floods in stratified reservoirs
… very technically challenging, even when applying waterflood, gasflood, or WAG (water-alternating gas) processes. To date, relatively few field or pilot applications of foam flooding have been conducted due to an incomplete understanding of how foam will behave in the field. The reservoir of …

Particle Detachment in Single-Phase and Two-Phase Flows in Porous Media
Hereby I present a PhD thesis by publications. This thesis includes seven journal papers, of which six have already been published in peer-reviewed journals and one has been submitted for publication and is presently under review. This thesis shows that the commonly used single particle-single …
