Definition - What does Geosteering mean?
Geosteering is a method that uses logging methods to steer the well in the indicated direction and within the pay zone.
Geosteering involves real-time use of logging tools such as logging while drilling (LWD) and measurement while drilling (MWD) to continually evaluate and place the horizontal wellbore in the optimal position.
It is a method of choice for drilling offshore and in deep water, as it maximizes efficiency due to increased reservoir exposure, increased production level and oil recovery, and helps offset the additional cost of an offshore drilling operation.
Trenchlesspedia explains Geosteering
Gesoteering can be used to improve the odds of success by remaining in the productive zone for longer drilling periods. The method is also great for optimizing horizontal wellbore positioning in the sweet spots within the reservoir.
It incorporates modern high-tech electronic equipment that is able to relay real-time approximation of the location of nearby geologic beds in relation to a wellbore or coordinate system.
The real-time information is obtained using MWD that steers the drill and LWD that generates logs representing various rock formation properties at depth.
Geosteering is a solution for meeting the demands of the energy industry while creating a lighter footprint for alleviating environmental concerns.
