Compass’ own Slim Hole MWD System is capable of providing Directional and Gamma Ray services in many types of wells, including short radius wells, at build rates not previously available through conventional MWD technology. It is the perfect tool for re-entry of wells where small production strings are used. For deeper drilling applications, the tool will facilitate keeping pressure losses to a minimum and flow to a maximum, for better cleaning and cooling. The tool has a long downhole life and is low maintenance, which is complemented by its long battery life and low power consumption. It is fully retrievable and increases efficiency by saving time and money by eliminating pipe trips.
