(2015-12-14)Acid fracturing is a widely used stimulation technique for carbonate reservoirs, and more efficient both technically and economically compared with propped fracturing. However, the performance of acid fracturing is hard ...
-
(2019-05-16)Most wells in conventional carbonate reservoirs are stimulated with acid, either by acid fracturing or by matrix acidizing. Both methods can result in effective stimulation in carbonate reservoirs, but currently there is ...
-
(2019-07-10)Closed-fracture acidizing (CFA) is a well stimulation technique that can be applied to stimulate carbonate reservoirs at the end of acid fracturing treatment to enhance the connectivity between the acid-fracture and the ...
-
(2020-07-27)Modeling acid fracturing process is challenging because of the coupled complex effects of flow through porous medium and fracture, chemical reaction in a geostatistic base, wormhole propagation and reservoir heterogeneity. ...

(Texas A&M University, 2008-10-10)Emulsified acids have been extensively used in the oil industry since 1933. Most of the available research and publications discussed mainly the application of emulsified acid in the field. A fair number of the published ...
-
(2015-12-01)Acid fracturing techniques have been widely practiced to enhance well productivity and ultimate recovery for low permeability carbonate reservoirs. The success of an acid fracturing treatment is evaluated based on the ...
-
(2013-05-01)Acid fracture conductivity and the effect of key variables in the etching process during acid fracturing can be assessed at the laboratory scale. This is accomplished by using an experimental apparatus that simulates acid ...
-
(2009-05-15)Success of acid fracturing treatment depends greatly on the created conductivity under closure stress. In order to have sufficient conductivity, the fracture face must be non-uniformly etched while the fracture strength ...
-
(2010-10-12)Success of acid fracturing depends on uneven etching along the fracture surfaces caused by heterogeneities such as variations in local mineralogy and variations in leakoff behavior. The heterogeneities tend to create ...
-
(2014-06-05)The acid fracturing process is a thermal, hydraulic, mechanical, and geochemical (THMG)-coupled phenomena in which the behavior of these variables are interrelated. To model the flow behavior of an acid into a fracture, ...

(2019-11-25)In this study, we conducted laboratory experiments of acid fracturing using San Andres dolomite downhole sample cores and regular HCl acid 15%. These samples have variation of anhydrite content from 1% to 43% based on XRPD ...
