Risk Analysis
As the industry has moved from drilling in 1,000’ of water depth to greater than 10,000’ of water
depth, Baker Hughes Drilling Fluids has developed new systems and processes to meet the increasing
challenges. Solutions developed include advanced systems and specialized fluid additives, new
laboratory and field instrumentation, and a complete rigsite management program.
Changes in environmental regulations, coupled with more demanding well profiles, led to the
widespread development of “Pseudo-Oil” muds. An understanding of kinematic viscosities and
temperature effects on rheological properties led Baker Hughes Drilling Fluids to introduce a
Synthetic Fluid, with an Isomerized Olefin (20) base, in 1994. This was the first deployment of an
IO, which subsequently became the industry standard in the Gulf of Mexico.
