Title: Innovations by Dongkeun Lee in Coiled Tubing Operations
Introduction
Dongkeun Lee is an accomplished inventor based in Sugar Land, TX (US). He has made significant contributions to the field of coiled tubing operations, holding a total of 2 patents. His work focuses on optimizing the efficiency and effectiveness of cleanout operations in hydrocarbon-bearing formations.
Latest Patents
Dongkeun Lee's latest patents include innovative systems and methods for estimating the position of solid fills and optimizing their removal during coiled tubing cleanout operations. These systems facilitate coiled tubing operations by generating a depth of solids origin (DSO) guess that represents the depth location of solids in a wellbore. The method utilizes a calibrated flow model to predict the amount of solids at a surface location of the wellbore based on the DSO guess. By comparing the predicted amount of solids to the measured amount at the surface, the DSO guess can be adjusted to match the actual DSO within the wellbore. This process allows for the adjustment of operational parameters to reduce the amount of solids at the DSO.
Another notable patent involves methods for real-time optimization of coiled tubing cleanout operations using downhole pressure sensors. This method includes acquiring downhole data via sensors within the coiled tubing system and identifying a density profile of fluids in the wellbore. The processing and control system interprets this density profile to estimate the reservoir pressure prior to cleanout operations, enhancing the overall efficiency of the process.
