Challenge: Drill an S-shaped well at high
ROP, identify gas/oil contact (GOC), and land the well below GOC in a highly
deviated section without the use of a chemical nuclear source for logging.
Solution: Use NeoScope sourceless
formation-evaluation-while-drilling service for identification of GOC without a
chemical source and Orion II telemetry platform for faster data
transmission.
Results: Maintained high ROP, identified GOC
in the target sandstone at 5,454 ft MD in real time, and obtained high-quality
spectroscopy data for quantitative lithology to set the 7-in liner without a
chemical nuclear source.
