Drilling Highly Depleted Formations with Engineered Particle Non-Aqueous Fluids (EP-NAF): South China Sea

A new fluid system (EP-NAF) has been utilized in the Malay Basin of the South China Sea to drill through highly depleted<br>sands with a non-aqueous fluid at elevated densities. The fluid contains sized particles to both bridge and prop open fractures<br>as they occur during actual drilling operations. Formation integrity is gained immediately and does not require additional<br>critical path rig time.
