New Directions in Foam and Aerated Mud Research and Development

Abstract

A review of foam and aerated drilling fluid technology is presented. The review includes an analysis of foam and aerated fluid rheology and flow-pressure loss models. Problems associated with the applications of current models are discussed. Suggestions for possible model modifications and needs for future research are offered. Recently, a new research initiative has been undertaken by the University of Tulsa to build an Advanced Cuttings Transport Facility (ACTF). Development and utilization of the ACTF will offer the industry an insight into the complex processes that govern fluid flow during drilling and production phases. The basic construction of the facility is in progress. The facility will eventually allow investigation of cuttings transport with incompressible and compressible drilling fluids at elevated temperature (200 °F) and elevated pressure (2000 psi). The design aspects of the ACTF and the scope of the project are discussed in the present paper.
