This collaboration between technology and operational expertise allowed the team to overcome the drilling challenges, ensuring continuous placement within the target...

... wells. Despite advancements, cement plug placement in wells continues to present challenges. One major concern is the potential for stuck drillpipe caused by differential pressure in a lost-circulation zone. Another critical issue is cement plug contamination with mud, which compromises isolation...

... Abstract Cementing is a key project connecting drilling and production. The prerequisite for ensuring the safety of cementing job is to accurately design the thickening time and remain slurry unset during placement. Circulating temperature is an important factor in cement slurry design...

... drilling (MPD) equipment against a check valve inside the drill pipe. The backpressure schedule and pumping rate was optimized to avoid influx or losses during cement placement. High slurry contamination was expected inside the pipe without any mechanical separators. At the surface, after verifying...

... Abstract Navigating thin carbonate reservoirs (3-5 ft thick) with significant dip variations poses a major challenge in achieving accurate well placement and maximizing reservoir contact. Close-to-the-bit measurements are essential for the early detection of formation changes, enabling...

... of directional flexibility and navigation control as compared to conventional OH MSFs, which have very strict limitations for dogleg and inclination citing risk of deployment complexities with the stiff completions string. Having no OH packers eliminates the need to record open hole logs for packers placement...

... Abstract Ultra-deep electromagnetic (EM) technology has been used for over a decade for well placement operations. As the measurement primarily responds to resistivity variations around the wellbore, it has been used to map lithological boundaries and fluids enabling geosteering the well path...

... environmental issues and cost effects. Instead, LWD-NMR combined with Deep Azimuthal Resistivity tools emerges as the optimum solution to evaluate the formation and optimize well placement in the best reservoir quality. NMR is utilized for accurate porosity because it is independent of lithology. The T2...

... LWD sensors usually measure formation properties around the well trajectory, Deep azimuthal electromagnetic (EM) tools are often used to map boundaries further away from the wellbore to improve well placement. The resistivity of the surrounding formation and resistivity contrast with the adjacent...
