The main components of drilling mud are sodium bentonite and water. Maintaining the rheological properties of the mud during drilling is crucial for smooth drilling operations. When drilling through sandy or fragmented formations, water from the mud can be absorbed by the formation, causing filtration and resulting in fluid loss. This filtration alters the mud’s rheological properties, slows circulation, allows cuttings to accumulate around the drill bit forming a filter cake, and disrupts the pressure balance of the wireline drill string. These effects can lead to drill string sticking or wellbore collapse, slowing or even halting drilling operations. To prevent fluid loss, always use our fluid loss additives, which preserve mud rheology, prevent filtration, and are selected according to the chemical properties of the formation being drilled.
