Speaker:    Dr. Asadollah Hayatdavoudi



Dr. Asadollah Hayatdavoudi is Professor of Petroleum Engineering and Research Professor of Engineering at the University of Louisiana-at-Lafayette. He holds a BS degree in Petroleum Engineering from the University of Southwestern Louisiana (now University of Louisiana at Lafayette) and MS and PhD in Mining Engineering and Mineral Engineering (Geochemical  Engineering), respectively, from the University of Wisconsin-Madison. He is a 1993 recipient of the regional SPE Service award, a former SPE short course instructor, a practicing Registered Professional Petroleum Engineer in Louisiana and the 1990 Distinguished Professor of the UL Foundation. Over the past four decades, during his industrial consulting and academic teaching and research, Dr. Hayatdavoudi has worked extensively in the areas of Formation Damage Control, novel Drilling systems (with two consecutive world records in drilling), Casing Handling Systems, Solids Control, Petrophysics, Theoretical Seismology, Formation Evaluation, Well Completion, Production, Geochemical, Mining, and Geotechnical Engineering. As principal inventor, he holds more than 20 US and International Patents and has published more than 50 papers in various SPE, SME, ASME, SPWLA symposiums, journals, and trade publications.


Pickling the Shale Gas

We have been conducting shale research for more than four decades. Since the late 1960s, our work has dealt with troublesome shale as a source of well bore instability. We quickly found that the shale issues must be addressed by simultaneously taking into account the combined chemical, physical, and mechanical properties of the shale. To accomplish this, we introduced the thermodynamic properties of the shale based on its specific percentage of clay content. This technique, along with sound and practical petroleum engineering practices, guided us to successfully design the mud systems tailored for drilling long sections of troublesome shale and resolve the issues of well bore instability, ultrafine contamination, lost circulation, slow drilling, and many others. In addition to considering shale as a source of hazard, since the mid 1970s, we have been involved with research that considers shale gas/liquid as a viable economic source and how to best extract these natural energy resources from shale that could be categorized as “troublesome shale.” In this talk, regarding the extraction of natural energy sources, we share our recent findings related to the following questions:

1. At what specific sites is the shale gas stored within the shale mass? 2. For how long, at a minimum, should we shut-in the well after hydraulic fracturing for best gas production results? 3. How do the micro-fracture networks grow? 4. What kind of fractures develop in these networks? 5. At what specific sites do these micro-fracture networks initiate? 6. Why do not these micro-fractures develop in some samples that have almost the same type and concentration of clay minerals? 7. How many types of gas flow behavior can we expect from a “pickled” shale gas? 8. Is the gas flow from the “pickled” shale gas cyclic within a short time or steady over a long period? 9. Could there be any relationship between the activated sites of “free gas,” which may result in the development of localized “pore pressure” in the “pickled” shale mass, and the appearance of the fault within the same sample? 10. Is the fault appearing in the “pickled” shale sample strictly a normal fault? 11. Is there any water in the shale gas that appears seemingly dry? 12. And many others…
