R-Seal™

Seepage losses sealant for reservoir applications

Description

R-Seal™ is a versatile and highly effective blend of acid-soluble particles and sealing

agents, available in both Regular and Fine sizes. Designed to address and mitigate losses

in the production zone, R-Seal™ boasts a 97% acid-soluble formula, making it an ideal

solution for preventing and curing circulation losses during drilling operations. Whether

used as a sweeping agent or a spotting pill, R-Seal™ ensures optimal performance and

reliability.

Application

R-Seal™ enhances well ability to withstand higher mud weights, allowing better control of wellbore stability. A higher fracture pressure margin reduces the risk of lost circulation by enabling safe management of pressure surges during drilling and tripping operations. It also expands the operational drilling window, providing more flexibility in handling unexpected pressure variations and improving overall well control and safety. Ultimately, it contributes to efficient, safe, and cost-effective drilling operations.

Benefits

• Over 97% acid-soluble formula, ideal for reservoir losses.
• Easy and fast mixing.
• Compatible with all types of mud (water-based, oil-based, or synthetic-based).
• Does not affect rheological mud parameters.

Reservoir Protection: R-Seal™ provides effective reservoir protection by minimizing formation damage. Its acid-soluble nature ensures that it can be easily removed during well completion, preserving the integrity and productivity of the reservoir.

Treatment Recommendation

R-Seal™ can be used in several methods.
• Drilling Fluid Additive: 2-10 lbs/bbl of R-Seal™ added to the drilling fluid.
• Regular Sweeps: 10-20 lbs/bbl of R-Seal™ mixed in a slugging pit.
• Sever Loss Scenarios: 20-50 lbs/bbl of R-Seal™ for loss scenarios of 30 bbl/hr or more.
For complete loss of circulation, it is advisable to use DFT’s FRAKPLUG-RF™ along with an R-Seal™ spot for optimal results.
