MWD System
Ease of maintenance, flexibility and reliability, thereby providing greater availability is why most customers worldwide are moving from the collar integrated systems to our probe based systems. These systems are designed for easy transportation, ideally suited to the Nigerian environment. Our directional module operates on a windows based full color graphics LCD screen, allowing for easy viewing and interpretation. Long battery life is also guaranteed due to high end electronics that consume minimal power at all times. Down linking capability allows the tools operation to be modified without a cost trip out of hole, thereby saving thousands of dollars in rig time to our customers.
