Title: Innovations by Qusai A Darugar in Lost Circulation Materials

Introduction

Qusai A Darugar is an accomplished inventor based in Houston, TX, known for his significant contributions to the field of oilfield operations. He holds four patents that focus on innovative solutions for reducing lost circulation in wellbore fluids. His work is particularly relevant in the oil and gas industry, where maintaining fluid integrity is crucial for operational efficiency.

Latest Patents

One of his latest patents is titled "Encapsulated Lost Circulation Materials Based on Shape-Memory Polymer Foam." This invention involves a particulate core that includes a compressed shape-memory polymer foam and a disintegrating agent. The disintegrating agent can be a phase change material or a gas-producing material, encapsulated within a shell. The method aims to reduce lost circulation by introducing this material into a subsurface wellbore fluid, where heating the disintegrating agent causes the shell to break, releasing the foam to fill voids or fractures.

Another notable patent is "Encapsulated Lost Circulation Materials Based on Swellable Elastomers." This method also involves introducing a wellbore fluid containing an encapsulated material with a core of elastomer and a disintegrating agent. Similar to the previous patent, heating the disintegrating agent leads to the release and expansion of the elastomer, effectively filling voids in the subsurface formation to minimize fluid loss.
