(2022-03-02)Utilizing fluids in oil and gas drilling operations is unavoidable. Chemical properties of the fluid are critical, as they directly affect drilling performance and most importantly, formation damage in production zones. ...
-
(2014-12-09)Clay swelling and fines migration can cause formation damage of hydrocarbon bearing zones and prevent economic realization of oil/gas wells. Identification and management of clay particles in the formation is a necessary ...
-
(2013-08-07)Viscoelastic surfactants (VES) have been widely used in acidizing and acid fracturing. They are used as diversion agents during matrix acid treatments and leakoff control agents during acid fracturing. At high temperatures, ...
-
(2021-01-11)Solids found in drilling fluids, particularly weighting materials, can cause significant formation damage due to plugging of pores. This study investigates formation damage caused by using an oil-based drilling fluid system ...
-
(2012-10-25)Carbon dioxide (CO2) sequestration is defined as the removal of gas that would be emitted into the atmosphere and its subsequent storage in a safe, sound place. CO2 sequestration in underground formations is currently being ...
-
(2012-02-14)Iron control during acidizing plays a key role in the success of matrix treatment. Ferric ion precipitates in the formation once the acid is spent and the pH exceeds 1-2. Precipitation of iron (III) within the formation ...
-
(2013-01-18)Clay stabilizers are means to prevent fines migration and clay swelling, which are caused by the contact of formation with low salinity or high pH brines at high temperature. Previous clay stabilizers including: Al and Zr ...
-
(2019-02-27)Removing oil-based drilling fluid (OBDF) filter cake is a difficult task. Low removal efficiency of filter cake may result in pay zone damage, including drilling fluid filtrate incompatibilities with reservoir fluids, fines ...
-
(2020-11-24)Hydraulic Fracturing (HF) is an effective technique for hydrocarbon extraction from low-permeability shale reservoirs. It involves injecting a mixture of pressurized water, sand, and small amounts of chemicals into wells ...
