Czy nie raczej o coś takiego chodzi?

Branżowego terminu też nie znalazłem, ale zapewne o to chodzi, jak sugeruje P. Jarosław Bartkowiak.

materiał do regulacji zasobów wody

Tak strzelam na podstawie fragmentu podanego w referencjach poniżej

What is regulated is flow of fluid media.

Full quote
As used herein, the term “spotting fluid” refers to fluids or slurries used downhole during spotting operations, and can be any fluid designed for localized treatment of a downhole region. In one example, a spotting fluid can include a lost circulation material for treatment of a specific section of the wellbore, such as to seal off fractures in the wellbore and prevent sag. In another example, a spotting fluid can include a water control material. In some examples, a spotting fluid can be designed to free a stuck piece of drilling or extraction equipment, can reduce torque and drag with drilling lubricants, prevent differential sticking, promote wellbore stability, and can help to control mud weight.

As used herein, the term “water control material” refers to a solid or liquid material that interacts with aqueous material downhole, such that hydrophobic material can more easily travel to the surface and such that hydrophilic material (including water) can less easily travel to the surface. A water control material can be used to treat a well to cause the proportion of water produced to decrease and to cause the proportion of hydrocarbons produced to increase, such as by selectively binding together material between water-producing subterranean formations and the wellbore while still allowing hydrocarbon-producing formations to maintain output.

Definition:

Spotting Fluids
Operators know they are working against time when differential sticking stops their drill pipe. By applying our spotting fluids within six hours of an occurrence, the drill team stands a fighting chance of seeing the fluids penetrate the filter cake to break it up - thereby freeing the pipe.
