At Chinook, the large majority of our geosteering geologists are former wellsite geologists, intimately familiar with all rig operations and comfortable with the constant communication and flow of information needed for this type of work.
Focusing on multiple aspects of the drilling process, our geosteering geologists provide:
Our geosteering geologists have experience navigating reservoirs based on MWD/LWD parameters, gas ratios and proximity data (ranging). Navigating the reservoir is most often done by correlating MWD or LWD curves recorded over the lateral section with log profiles from control wells (stratigraphic wells or pilot holes). By overlaying curves on a TVD scale, geosteering geologists pinpoint the location of the drill bit in the structure, and can point the wellbore to the desired target within the reservoir with extreme accuracy.
Successful geosteering is done when the data used is streamed in real time, supervision is continuous while drilling, and a specialised software is used for precise interpretation.
Geosteering approaches can vary:
