(2017-07-11)AlCl₃ has been long used as a retarding agent for mud acid, its applications studied in the lab and tested in the field. The theory and mechanism of AlCl₃ retardation have been investigated in many projects involving mud ...
-
(2011-05-09)This work proposes to survey new chemical knowledge, developed since 1984, on fluid additives used in matrix stimulation treatments of carbonate and sandstone petroleum reservoirs and describes one method of organizing ...
-
(2012-07-16)Matrix acidizing is a well stimulation technique used to remove formation damage in the near wellbore region. But it comes with an associated set of challenges such as corrosion of the tubulars and iron precipitation in ...
-
(2018-02-09)Asphaltene precipitation, flocculation, and deposition are vital problems that may cause serious damage to reservoirs, wells, and production facilities. Asphaltene precipitation may occur during primary depletion or acidizing ...
-
(2017-07-31)The viscoelastic surfactant (VES) is one of the newest chemicals that have been used as diverting agents to divert the acid to the desirable zones through directing the acid to the lowest permeability formations by building ...
-
(2014-04-30)Acid jetting is a well stimulation technique that is used in carbonate reservoirs. It typically involves injecting acid down hole at high flow rates through small orifices which cause high velocities of acid to strike the ...
-
(2014-05-01)Although fluoboric acid (HBF_(4)) has long been known as one of the low-damaging acid treatments for clayey sandstone formations, little is known of its chemistry which could explain the mixed results of fluoboric acid in ...
-
(2019-05-21)Reactive nature of steam and clay minerals may lead to formation damage and flow assurance issues. This dissertation presents experimental investigation of oil recovery and changes in petrophysical properties as a function ...
-
(2016-12-09)Carbonate rocks have complex heterogeneities that result from syn- and post-depositional stressors. These heterogeneities invariably affect the movement of fluid through the formation. When considering an acid treatment ...
-
(2009-06-02)Horizontal wells are drilled to achieve improved reservoir coverage, high production rates, and to overcome water coning problems, etc. Many of these wells often produce at rates much below the expected production rates. ...
-
(2013-05-07)In this study, the optimum conditions for wormhole propagation in horizontal well carbonate acidizing was investigated numerically using a horizontal well acidizing simulator. The factors that affect the optimum conditions ...
-
(2013-12-05)Fracture acidizing is a well stimulation technique used to improve the productivity of low-permeability reservoirs, and to bypass deep formation damage. The reaction of injected acid with the rock matrix forms etched ...
-
(2015-11-13)Acid stimulation is a widely used well treatment technique applied to enhance oil production by creating conductive channels through the formation, resulting an improved flow property. Viscoelastic surfactant (VES)-based ...
