Title: Zongcai Feng and Seismic Imaging Innovation.

Introduction.

Zongcai Feng is an inventor based in Houston, Texas, whose patent work addresses seismic imaging for subsurface analysis at wellsites. His disclosed invention focuses on producing high-fidelity, high-resolution seismic images to support wellsite decisions.

Latest Patents.

Feng is associated with 1 patent, titled “Methods and Systems for Seismic Imaging.” The method receives seismic data from equipment at a wellsite and uses it to recover an initial estimate of an earth model. It then performs a depth-migration workflow, which may use least-squares full-waveform-inversion-derived reflectivity (LS-FDR), and revises the initial model based on the workflow’s results. The resulting optimal earth-model estimate is used to generate a seismic image that can be displayed to a user, who may use it to guide a wellsite action.

Career Highlights.

Feng is associated with Schlumberger Technology Corporation. His patent describes a workflow that combines seismic data, earth-model estimation, and depth migration to improve subsurface imaging.
