Cuttings Transport With Foam Under Simulated Downhole Horizontal Conditions

The use of drilling foams is increasing because foams exhibit properties that are desirable in many drilling operations. A good knowledge of cuttings-transport efficiency under downhole conditions is essential for safe foam drilling. Previous cuttings-transport studies with foam were limited to low-pressure and ambient-temperature (LPAT) conditions. An experimental study of cuttings transport with foam in a horizontal annulus was performed under simulated downhole conditions.
