Oil Base and Synthetic Base Muds Nonaqueous Fluids Testing

Hpht Fluid Loss Testing Device

The field tests for rheology, mud density, and gel strength are accomplished in the same manner as outlined for water-based muds. The maindif-ference is that rheology is tested at a specific temperature, usually 120 F or 150 F. Because oils tend to thin with temperature, heating fluid is required and should be reported on the API Mud Report. Sand Content Sand content measurement is the same as for water-base muds except that the mud's base oil instead of water should be used for dilution. The...

Water Base Muds Testing

Mud Balance Used For Drilling

To accurately determine the physical properties of water-based drilling fluids, examination of the fluid is required in a field laboratory setting. In many cases, this consists of a few simple tests conducted by the derrickman or mud Engineer at the rigsite. The procedures for conducting all routine drilling fluid testing can be found in the American Petroleum Institute's API RPB13B. Density Often referred to as the mud weight, density maybe expressed as pounds per gallon lb gal , pounds per...
