Pilot Retrievable Reseatable (MWD)

Our efficient, low-maintenance MWD System is designed for easy transportation and assembly. Built to perform in harsh environments, the MWD System can operate in temperatures up to 175ºC and under pressure up to 20,000psi.

Description

The positive-pulse tool accommodates a number of probe configurations, ensuring top performance in a variety of flow ranges and collar diameters from 3.5in outside tool diameter. This modularity, combined with the MWD System's rugged and retrievable design, minimizes rig downtime and reduces financial risk.

The superior technology of BlueStar's MWD System includes a reliable and efficient Directional Module. Straightforward to configure, it allows operators to avoid "hand decoding". The windows-based, full color graphics LCD screen of the Rig Floor Display can be readily viewed in normal rig operating conditions. In addition, the hardware selection is power efficient to reduce consumption and extend useful battery life. The MWD System's down linking capability also allows tool operation without tripping controlling instruments.

Additional resources include the onsite installation of a natural gamma ray sensor, a down hole memory, and hardcopy logs.
