Prof. HAN Dehua, director of Rock Physics Laboratory form the Geo-technology Research Institute at University of Houston was invited by the Ultrasonic Physics and Exploration Laboratory (UPEL) of the Institute of Acoustics for academic exchanges on July 3.

9:00 a.m., XU Delong, the academic secretary of UPEL, presided over the seminar and introduced Prof. HAN to the attendees. Prof. HAN is an internationally famous geophysicist, having graduated from the Standford University and been working on rock physics for more than 40 years.

And then, Prof. HAN started his presentation “Seismic Characterization of Reservoir Shale” with “Shale gas will rock the world”. His lecture focused on seismic rock physics: rocky and fluid properties and integrating rock properties into seismic for reservoir exploration, evaluation, characterization, and monitoring.

In the beginning of Prof. HAN’s lecture, he intruded the background and meaning of reservoir shale, “Shale gas will revolutionize the industry and change the world in the coming decades”. And then he reviewed the history, trend and potential of the reservoir shale. Afterwards, he recommended the technologies such as horizontal drilling, new hydra-fracking technology and better completion, which can be used to develop the shale gas. At last, he emphasized the contributions of rock physics to the shale gas in details, including the evaluation of resources, TOC and maturation, porosity, saturation, pressure, producibility, permeability and frac-bility. During the lecture, many vivid examples illustrating the applications of rock physics to reservoir shale were demonstrated.

After the lecture, Prof. HAN had a warm discussion with the attendees and visited the high temperature and high pressure tri-axis rock physics laboratory of UPEL.
