The Mudgard™ workstring filter can be used in any drilling application to prevent debris-related hazards and reduce the likelihood of NPT. A cost-effective solution for BHAs that have impeller or modulated flow control, the Mudgard filter is a proactive measure in the protection of drilling assemblies from rock, scale, sulphates, carbonates, silicates, and any other insoluble material that may cause damage. This advanced tool has been engineered by studying computational fluid dynamics to maximize debris retention while assuring high volume throughput with minimal pressure drop. Its internal dual filter screen is highly resistant to erosion.

Mudgard filter can also be run in conjunction with other throughbore wireline-accessible drilling tools, such as the WELL COMMANDER™ ball-activated drilling circulating valve and the Magnoshield™ drillstring magnet. Designed with a single-piece collar carrying the dual-filter screen, the Mudgard filter is complete with a contingency central bypass that facilitates wireline chemical source recovery in a single trip. The central bypass has also been engineered to give overpressurization protection should the filter become overloaded with solids and debris.
