Highly Compressible Drilling Fluids Highly compressible fluids are generally associated with underbalanced drilling. They have densities ranging from 6.95 ppg, with back pressure, down to 0 ppg. They are comprised of gasses, mists, foams, and aerated liquids with high gas to liquid ratios. Conventional drilling motors are not designed for use in compressible fluids and have problems including shortened life, stalling, and runaway. INTEQís ADM incorporates a special design that employs much larger chamber volumes to give lower output rotational speeds for a given flow rate and lower pressure drops than conventional motors. This provides the advantages of improved motor efficiency, fewer stalls versus conventional motors, and reduced chances of overspeed. They can be used with the entire range of compressible fluids and liquid drilling fluids as well.

The PERFFLOWÆ fluid system is one of INTEQís Drilling Fluidsí drill-in fluids. The system uses polymers for viscosity and fluid loss control and incorporates sized calcium carbonate for bridging off the pore throats of the production formation. The fluid loss additives and bridging agent are designed to minimize fluid invasion and form an easily removable filter cake. PERFFLOWÆ systems can be made up with fresh water or a brine depending on fluid density requirements.
