Improving Oil Displacement Efficiency by Wettability Adjustment

Transactions of the AIME, 1959
Abstract Because of unfavorable wetting conditions much residual oil is left when a porous material is flushed by water. Methods suggested to change reservoir wetting to improve oil displacement efficiency are generally expensive.

Efficient Coding Scheme of Displaced Frame Difference

2009 Sixth International Conference on Fuzzy Systems and Knowledge Discovery, 2009
The improvement of video coding performances is depended on how to improve the coding performances of motion compensation prediction error information, which is also called Displaced Frame Difference (DFD). In this paper, a novel tree structure multiscale ridgelet dictionary based multi-atoms matching pursuit DFD coding scheme is proposed. Firstly, the

How Realistic is the Calculated Cementing Displacement Efficiency?

IADC/SPE International Drilling Conference and Exhibition, 2020
Abstract Primary cementing is a crucial task in the completion of oil and gas wells, as it is potentially meant to provide zonal isolation, and prevent uncontrolled flows and environmental hazards. Much research has been conducted to find the key techniques for obtaining the maximum displacement efficiency during cementing operations ...

Factors Influencing the Efficiency of Miscible Displacement

Transactions of the AIME, 1959
Published in Petroleum Transactions, AIME, Volume 217, 1959, pages 1–8. Abstract This paper presents results of an experimental investigation of factors that control the efficiency with which oil is displaced from porous media by a miscible fluid. The study was made to elucidate the relevant processes

Displacement efficiency of faults and fractures: Discussion

Journal of Structural Geology, 1987
Abstract Higgs and Williams present a kinematic classification of one-event faults. It is our contention that the new terms which they propose are misleading and that the conclusions drawn cannot be reconciled with the findings of earthquake seismologists.

Integrated Global Optimization of Displacement Efficiency in Hydrocarbon Reservoirs

SPE Latin American and Caribbean Petroleum Engineering Conference, 2003
AbstractIn this paper, an integrated numerical technique is presented to implement global optimization of displacement efficiency in hydrocarbon reservoirs. This technique chooses the net present value (NPV) as an objective function, which accounts for production- and injection- performance as well as reservoir performance.

An Efficient Gas Displacement Project Raleigh Field, Mississippi

Journal of Petroleum Technology, 1965
Abstract In the unitized Raleigh field, gas from separators, treaters and small gas reservoirs is being used for pressure maintenance of the larger oil pools. Sufficient gas has been available to maintain pressure within 90 per cent of original in two of the larger Lower Cretaceous Houston oil pools.

Energy Efficient Actuation Using Variable Displacement Hydraulic Control

SAE Technical Paper Series, 1985
<div class="htmlview paragraph">The use of variable-displacement hydraulic motors for advanced aerospace actuation can provide a 50 to 80 percent savings in average power consumption over conventional fixed-displacement devices. The characteristics of a variable-displacement hydraulic control system are discussed in relation to conventional fixed-
