Colmatant acid-soluble carbonate

Acid-soluble colmatant is one of the most popularchemical reagents for drilling fluids.

In the oil and gas industry, when drilling wells, one of the most important tasks is to prevent water from seeping into the well cavity. This task is achieved by treating the walls of the well with a special reagent - an acid-soluble colmatant, as a result of which the pores of the walls of the well are clogged.

Acid-soluble colmatant basically consists of natural marble, which has passed several stages of grinding.

Advantages of using acid-soluble colmatants:

• Cementing and colmatation of borehole soils prevents the ingress of near-ground water and soil particles into the working drilling mud.
• Increases the efficiency of productive reservoirs and prevents their contamination.
• The colmating and crusting effect of the use of acid-soluble colmatants is stable over time and persists until the end of drilling operations.
• Eco-friendly and safe product
• After the completion of drilling operations, the soil is decolmated by treatment with hydrochloric acid, under the action of which the marble filler is dissolved by 98.9%, and the permeability of the near-collector soils is restored.

Main fractions of acid-soluble colmatants:

• 10-40 microns;
• 45-75 microns;
• 100-160 microns.

The Basis mineral powder plant produces acid-soluble colmatants according toTU 5711-013-33911171-2005, observing the appropriate storage and transportation conditions.

The most important quality of colmatant is its ability to dissolve in hydrochloric acid. Therefore, for colmatation, ground dolomite is not used, but only microcalcite-calcium carbonate, 98% soluble in mineral acids.

The plant of mineral powders "BASIS" warns: 

As a colmatant, the use of ground dolomite is not allowed, because it is much slower and does not completely dissolve in hydrochloric acid, which reduces the efficiency of oilfield services!
