Modern production methods and environmental constraints demand chemical solutions. And
as oilfields age, the need for chemicals to ensure steady production increases. Production …

Fouling mitigation in underground reservoirs enhances the permeability and the flow
capacity of production or injection wells and is carried out by reservoir stimulation methods …

In‐situ gelled acids are used for acid diversion in heterogeneous carbonate reservoirs.
However, most of the gelled systems are based on anionic polymers that are difficult to clean …

Diversion in heterogeneous carbonate reservoirs plays the most important role to the
success of acidizing. Without the use of diversion, more acid preferentially flows into the high …

Polymer-based acids exhibit some viscoelastic properties. Therefore, the objectives of this
study are to determine the elastic and viscous properties of these acids, how these …

In-situ-gelled acids that are based on polymers have been used in the field for several years
and were the subject of many laboratory studies. These acids are used in stages to block the …

The use of in-situ cross-linked acids (ICAs) is common in stimulating oil and gas reservoirs.
However, their rheological models have not been widely incorporated into simulation …

In-situ gelled acids based on polymer have been used in the field for several years, and
were used in the field in stages between the regular acids. Literature survey reveals that …

Lab test of polymer-based in-situ gelled acids reveal that polymer and other additives
separate out of the acid when these acids are prepared in high salinity water. In coreflood …

Hydrochloric (HCl) acid is the most common stimulating fluid used in acidizing job due to its
strong acidic property and low cost to create or enlarge existing wormhole within the …
