Details

Replacing an oil-based drilling fluid system with the HydraGlyde high-performance water-based drilling fluid system enabled a Permian operator to drill a 2-mi lateral in less than 5 days. The system eliminated the need to run a contingency liner and prevented NPT caused by water flow. The operator achieved a cost savings of 59%.

High-Performance Water-Based Drilling Fluid System Eliminates NPT and Water Flow Challenges

Permian operator drills 2-mi lateral in less than 5 days using HydraGlyde system

The operator's goal: drill lateral using water-based fluid

A 19,000-ft well in Martin County, Texas, presented complex curve and lateral geometry next to a recently hydraulically fractured well. Torque and wellbore inhibition challenges required the lateral to be drilled using water-based fluid.

Initial attempt: replace fluid system after contamination of oil-based mud

The operator initially used an oil-based drilling fluid system until a freshwater flow dropped the oil/water ratio to 52:48 and resulted in contamination of the oil-based mud (OBM) in the hole. The only potential solution was to run a contingency liner to shut off the flow. Running this extra string of casing would have caused delays in the delivery of the well, overspending of the AFE, and a continued risk of OBM contamination in the lateral.

Schlumberger solution: overcome water flow challenges

The HydraGlyde system is an efficient, flexible drilling fluid solution that reduces torque and drag and delivers oil-mud-comparable ROP, exceptional hole cleaning, and wellbore stability in long-lateral sections while reducing restrictive costs and decreasing environmental impact.

Result: reach TD on schedule

The operator replaced the oil-based drilling fluid system with the HydraGlyde water-based system for the curve. The system tolerated losses and water flows while drilling and negated the liner run in the curve. The operator drilled a 2-mi lateral in less than 5 days to TD with no bit trips. The average ROP stayed at just over 2,000 ft/d. The solution helped the operator achieve a cost savings of up to 59% in the lateral section, with zero diesel additions, zero OBM costs associated with lost fluid, and reduced disposal costs from using a water-based system.

I would like to express my gratitude toward the effort that the M-I SWACO team put out when facing this unusual technical challenge and their flawless execution of the plan. The system was built on location in such a short notice, and it was maintained to enable the team to drill the well to TD with no issues. The team displayed outstanding technical knowledge, a professional attitude, and a commitment to support of drilling operations.
