(2014-04-28)Seawater is the only viable water source for many offshore wells with dolomite formations. For these wells it is important to use compatible fluids when stimulating to avoid damaging the formation with calcium sulfate ...
-
(2015-03-25)Hydrochloric acid (HCl) is the most commonly used stimulation fluid for high-temperature wells drilled in carbonate reservoirs due to its high dissolving power and low cost. However, the high corrosion rate of HCl on well ...
-
(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 ...
-
(Texas A&M University, 2006-10-30)Well stimulation techniques are applied on a regular basis to enhance productivity and maximize recovery in oil and gas wells. Among these techniques, matrix acidizing is probably the most widely performed job because of ...
-
(2010-07-14)In matrix acidizing, the goal is to dissolve minerals in the rock to increase well productivity. This is accomplished by injecting an application-specific solution of acid into the formation at a pressure between the pore ...
-
(2012-10-19)A solid breaker is used to reduce the viscosity of the gel at pH range of 4-5 for in-situ gelled acids with Zr4 cross-linkers utilize. However, the literature survey confirmed that solid breakers caused a premature reduction ...
-
(2018-03-27)In carbonate acidizing, wormhole development is crucial to the stimulation result. The acid reactivity and injection rate both play important roles in this process. Because the reactivity of HCl with carbonate is high, it ...
-
(2019-07-03)Since the inception and use of matrix acidizing to stimulate wells, the oil and gas industry has continued to develop new and improved fluids and materials for chemical diversion. However, the effects of chemical diversion ...
-
(2012-12-10)Core flooding is a commonly used experimental procedure in the petroleum industry. It involves pressurizing a reservoir rock and flowing fluid through it in the laboratory. The cylindrical rock, called a core, can be cut ...
-
(2017-10-17)One of the factors for the success of matrix acidizing of carbonate reservoirs is the selection of appropriate stimulation fluids. Till date, the most common acid for carbonate stimulation is HCl due to ease of its ...
-
(Texas A&M University, 2008-10-10)Design of matrix acidizing treatments of carbonate formation is still a challenge although extensive research has been done on it. It is necessary to estimate acid distribution along the wellbore. This estimation is very ...
-
(2012-07-16)The goal of this work was to evaluate matrix acidizing treatments of vertical and horizontal wells in carbonate reservoirs. Twenty field cases for acidizing treatments were analyzed by evaluating the skin factor evolution ...
