2024年1月23日 · Optimized tubing: Liners allow you to use larger tubing sizes for optimal production flow. Reduced wellhead load: Lighter liners mean less stress on your wellhead and surface piping. Heavy-duty solutions: Scab tie-back liners provide extra strength through demanding zones. Drilling flexibility: Use tapered drillstrings with ease thanks to liners.

Liner drilling is adding a bit to a shorter length of casing that has a modified liner hanger and running tools on top of it and continuing with drill pipe to the surface. Liner drilling does not require rig or BOP stack modifications. There are two major benefits to casing and liner drilling.

2021年3月18日 · The drilling casing liners allow deeper drilling & completion operations by isolating lost circulation zones & prevent Mud Losses / Lost Circulation Problem, high-pressure intervals, and sloughing intervals. Their use will also:

2017年12月10日 · In this article, we will provide detailed steps for Liner Hanger Setting & Cementing Procedures. The main two types of Liner Hanger are: Mechanical liner hangers require manipulation of the Drill Pipe (Check also: Drill Pipe Specifications) to engage the …

Liner drilling eliminated a dedicated liner run through a high-loss gassy salt zone and reduced rig time by multiple days in the deepwater Gulf of Mexico.

Drill and run liner confidently—in one trip. The SureTrak service combines a rotary steerable system with a liner. Running the liner while drilling keeps the wellbore stable and eliminates the need to pull the drillstring to run casing—reducing your risks and nonproductive time (NPT).

2023年5月23日 · The liner while drilling service is a sustainable technology which combines 4.75in rotary steerable system BHA (Bottom Hole Assembly) with various logging tools, 8.75in hole opener/reamer, a mud motor, and a 7in liner with 8.5in reamer bit to help overcome the challenges while drilling in zones with low formation pressure and unstable formations.

Liner drilling (LD) is a proven technology for addressing such drilling hazards as lost circulation, depletion, wellbore stability, and wellbore ballooning issues. Perhaps the most outstanding feature of LD is the fact that no rig modifications are required; the same surface equipment that is …

Casing/Liner while drilling is a very good option to precisely minimize the time invested in drilling and completion procedures. This study presents a Casing Design procedure for Casing/Liner while drilling. The selected casing would be able to withstand the …

Running liner strings in this scenario can potentially increase fluid overflow on the rig floor when auto-filling the string, which can increase the potential for health, safety, and environmental (HSE) risks. To address the challenges in this well section, Halliburton proposed the SuperFill™ surge reduction system.
