Title: April Shi and a Patent for Lost-Circulation Control

Introduction

April Shi is a woman inventor associated with Katy, Texas. Her patent work addresses lost circulation during reservoir drilling operations, a challenge in which drilling fluid escapes into formations rather than remaining in the wellbore.

Latest Patents

Shi is associated with 1 patent, titled “Biodegradable and Acid Soluble Materials for Control of Loss of Circulation in Reservoir Drilling Operations.” The patent describes a lost-circulation pill containing luffa fiber or sponge, sized carbonate or degradable synthetic material, and brine. The formulation is designed to help form a plug in a lost-circulation zone, while its biodegradable and acid-soluble materials support removal or degradation after use.

Career Highlights

The patent’s approach combines a luffa component with particles, flakes, or fibers made from carbonate or degradable synthetic material. The described method introduces the pill into a wellbore and forms a plug where circulation fluid is being lost.

Collaborations

Autumn Shepherd and Dorianne A. Castillo are identified as Shi’s coworkers. The provided information does not specify their roles in the patent or the extent of their collaboration.

Conclusion

April Shi’s patent focuses on a material-based method for controlling lost circulation in reservoir drilling operations, combining luffa, sized materials, and brine to form a plug in a wellbore.
