Baker Hughes, a GE company, has a new site. Want to see how we’re inventing smarter ways to bring energy to the world?
Baker Hughes' Dual Inclination service enables you to reduce TVD uncertainty and better define your wellbore/fluid contact positions without additional rig time, BHA components, or significant cost. Knowing geometric fluid contact depths is essential to understanding reservoir reserves and production during the well life cycle.
TVD control is critical to the success of your high-angle, long-reach wells. The use of a second inclination sensor that is already in the BHA is a cost-effective solution, adding increased reliability when rig costs are high. This improves accuracy to a crucial measurement with no additional equipment, rigsite personnel, or rig time.
Ensure valid dual inclination
This is not an off-the-shelf solution. Modern drilling assemblies often may include a second inclinometer, in addition to the directional MWD tool, but a valid dual inclination service requires much more than just access to two inclination measurements.
Our Dual Inclination service was commercialized following an extremely rigorous process of development and appraisal with independent validation by an international consultancy firm. We also worked with two major international oil companies for further refinement and validation.
Drill ahead confidently
With the use of a near-bit inclination (NBI) and the survey inclination, we offer a weighted average inclination that is more accurate than the use of survey inclination only. By utilizing the additional set of accelerometer readings from the NBI—calibrated to the standard of our MWD sensors—we can reduce the vertical uncertainty in your high-angle wellbore by up to 28%.
We achieve the reduction with the use of multiple, independent measurements. If two individual measurements have equal accuracy, but are fully independent, the average measurement will have an accuracy that is approximately 28% better than the individual measurements.
Data processing and quality control are automated, rigorous, and intentionally conservative. You’ll receive valid results at the rigsite so you can drill ahead confidently without the need for real-time expert evaluation. Rigsite results are subjected to detailed QC by our Survey Management group.
