Fluid Loss Control
Fluid loss control additives
Fluid loss control additives limit how much liquid escapes from a drilling fluid into permeable rock, and help it lay down a thin filter cake on the wall of the hole. Galaxy Drilling Fluids Pvt Ltd supplies 7 of them: 4 for water-based mud and 3 for oil-based mud.
Why fluid loss matters
Filtrate entering the formation can swell reactive shale and damage the reservoir, while a thick filter cake raises the risk of stuck pipe. Controlling the loss protects the hole and the rock around it, and the need grows as temperature and pressure rise.
The chemistry in this range
For water-based mud, sulphonated asphalt and liquid gilsonite seal the wall of the hole, an aluminium complex plugs fine pores in shale, and resinated lignite controls water loss at high temperature. For oil-based mud, natural asphalt is the conventional choice, GS Trol L is a liquid high-temperature alternative with no powder to handle at the rig, and GS Trol PD 700 is a polymer for high-pressure, high-temperature wells.

Products in this range
Water Based 4
-
Gel Asphatex
Sulphonated asphalt
Sulphonated asphalt. Seals the wall of the hole and steadies shale.
-
GS Aqua Gil
Liquid gilsonite
Gilsonite in liquid form. Seals the hole wall, and no dust when adding it.
-
GS Hexaplex
Aluminium complex
Aluminium complex. Plugs tiny pores in shale so pressure cannot push into it.
-
GS RX
Resinated lignite
Resin-treated lignite. Controls water loss at high temperature and keeps the mud thin.
Oil Based 3
-
GS Trol L
High-temperature liquid fluid-loss controller
Liquid high-temperature fluid-loss control – no black powder to handle at the rig.
-
GS Trol PD 700
Polymeric HPHT fluid-loss control application
Polymer fluid-loss control for high-pressure, high-temperature wells.
-
GS Trol / GS Trol HT
Natural asphalt
Natural asphalt. Controls fluid loss and steadies shale. HT grade for hot holes.
Frequently asked questions
What does a fluid loss additive do?
A fluid loss additive reduces the volume of liquid that passes from the drilling fluid into permeable formations, and helps form a thin, low-permeability filter cake. Galaxy Drilling Fluids Pvt Ltd supplies asphalt, gilsonite, lignite and polymer grades for both water-based and oil-based mud.
Which fluid loss additive suits HPHT oil-based mud?
In this range, GS Trol PD 700 is the polymer grade for high-pressure, high-temperature wells, GS Trol HT is the natural asphalt grade for hot holes, and GS Trol L is a liquid high-temperature option. Galaxy Drilling Fluids Pvt Ltd can recommend a grade from the section, mud weight and temperature.
