Oilfield drilling

The drilling operations demand a high knowledge of characteristics of the drilling muds, that contains many additives.

Their complex composition can modify the fluid density, rheology, or alkalinity. Magnesium can allow to master

these parameters.

Magnesium controls fluid density, rheology, or alkalinity

– In brine drilling mud, it plays the role of a scouring agent, used to keep the annulus clean. It also helps neutralize

acid gases released by the drilling process.

– Fluid alkalinity can be controlled by the use of Magnesium, particularly in clay-free polymer based fluids.

– To manage the rheology of drilling mud, Attapulgite can also be used. Combined with small quantities

(approximately 2% by weight) of Magnesium oxide, it allows an higher fluid viscosity.
