Effects of resident water and non-equilibrium adsorption on the primary and enhanced coalbed methane gas recovery.
(2006)
This study presents an experimental and theoretical procedure to investigate the effects of the resident water and time-dependency of the sorption process on coalbed and shale gas primary and enhanced recovery by simultaneous ...
Rheological and Flow Characteristics of Drag Reducing Surfactant Solutions in Straight Pipes and Annular Ducts
(2014)
Surfactants are well-known as effective drag reducers and viscosifying agents. The macroscopic properties of surfactants are dictated by the surfactant type and the condition of the solvent in which the surfactant is ...
Fluid dynamics of well-bore bottom-hole cleaning /
(1983)
A comprehensive series of tests were run on the University of Oklahoma drilling research laboratory rig investigating the variables which influence the rate of cutting removal. No rock cutting or penetration was done in ...
UNDERSTANDING THE FUNDAMENTAL DRIVE MECHANISMS FOR HUFF-N-PUFF ENHANCED OIL RECOVERY IN TIGHT FORMATIONS
(2019-12-13)
Unconventional oil and gas resources have recently become the major source of produced hydrocarbons in the US. The change in the energy landscape follows nearly two decades of technological breakthroughs including horizontal ...
A coupled model for the prediction of interformation flow through an abandoned well.
(1998)
Application of the model is demonstrated in a computer program which is used to evaluate hypothetical field cases of varying producer/injector combinations and user defined abandoned well location and conditions. The results ...
Numerical simulation of heterogeneous fractured gas reservoir systems with turbulence and closure stress effects.
(1982)
Although techniques for designing a fracture treatment are available, the intended results of these techniques are often not attained. The evaluation of fracturing treatments on low permeability gas wells is required to ...
Techniques for evaluating and improving the performance of the iron oxides used as barite substitutes in oil well drilling fluids.
(1982)
Barite is the main weighting agent for drilling fluids because it has the required advantage of high specific gravity together with chemical inertness, and it is non-abrasive. Barite is frequently contaminated with alkaline ...
Interpretation of horizontal well performance in multi-layer reservoirs by the boundary element method.
(1998)
The developed algorithm is applied to generate the dimensionless pressure and the dimensionless pressure derivative for a horizontal well in eight different systems whose analytical solutions are not available. These cases ...
PREDICTIONS OF CRITICAL GAS RATES IN HORIZONTAL AND DEVIATED WELLS
(2015-05)
The author’s intent through this work is to shed light on the current methods of predicting the onsets of liquid loading and to clarify that there is a difference in critical gas rate predictions between horizontal and ...
