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 (rock mechanics) 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 Engineer in Louisiana and Alabama and the 1990 Distinguished Professor of the UL Foundation. Over the past several decades, during his industrial consulting work and academic teaching and research, Dr. Hayatdavoudi has worked extensively in many areas of Petroleum Engineering including but not limited to Hydraulic Fracturing, Fluids (Design of Frac Fluid, Cleaning the Produced water, design of Completion Fluids, Novel Drilling Fluid Additives, Formation Damage Control), and Drilling systems (with two consecutive world records in drilling), and novel Solids Control Systems, and Casing Handling Systems, etc. Recently with his colleagues he discovered DNA in crude Oil which could have a significant impact on exploring for Oil and Gas and characterizing the extent and quality of the reservoirs. As principal inventor, he holds 20 US and International Patents and has published more than 70 papers in various SPE, SME, ASME, SPWLA symposiums, journals, and trade publications.
Topic : Biopetrophysics
A novel, sensitive technique for bacterial DNA fingerprinting – denaturing gradient gel electrophoresis (DGGE) of PCR amplified 16S rRNA genes – has been used to identify and classify bacteria found in six crude oil samples obtained from an operating company. The samples were taken from two separate wells, presumably drilled in the same reservoir. The procedure of fingerprinting bacterial communities present in the oil samples was as follows: DNA extraction from oil, DNA concentration, PCR amplification of 16S rRNA gene fragments from DNA isolated from oil, separation of the fragments by DGGE, sequencing DNA bands present in the gels, and finally identification of bacteria to which the these bands correspond. The existence of bacterial DNA in all the crude oil samples was proven after DNA concentration. Based on the bacteria identified from the two wells, it appears that one well drained oil from a fresh water environment associated with grasslands, whereas the second well drained oil from a coastal marine environment. This finding is in a sharp contrast to Chromatograms (fingerprints) which indicates both oil samples are the same. Other than fingerprinting the origin of oil, the bacterium in the reservoir fluids generally modifies the surface of pores and causes changes in permeability and rock wetability.
