Over the past four decades, during, his industrial consulting and academic teaching and research, Dr. Hayatdavoudi has worked extensively in the areas of Petrophysics, Theoretical Seismology, Formation Evaluation, Formation Damage Control, novel Drilling systems (with two consecutive world records in drilling), Casing Handling Systems, Solids Control, Well Completion, Production, Geochemical, Mining, and Geotechnical Engineering. As principal inventor, he holds more than 22 US and Interna- tional Patents and has published more than 80 papers in various SPE, ARMA, ISRM, SME, ASME, SPWLA symposiums, journals, and trade publications.

Rustam Nizamutdinov is senior undergraduate student in the petroleum engineering department at University of Louisiana at Lafayette. He plans to graduate in December 2016. Among his accomplishments prior to graduation is winning the first place prize among the major participating schools in Inaugural Student Paper competition of 56th SPWLA symposium in Long Beach, California held on July 19, 2015. Furthermore, he is a co-author with Joseph Kravets and Dr. Hayatdavoudi in paper presented in the 2015 - 49th ARMA symposium held in San Francisco, California. Additionally, he placed 3rd in SPE regional Student Paper competition held on April 26, 2015 at Pennsylvania State University in State College, Pennsylvania.


Abstract: “Increasing Pierre shale reser- voir volume using heat”

Pierre shale is soft and difficult to frac. This is because of its high clay content. To increase the chances of a successful standard frac, we find that shale of this nature could be fractured by using a heat medium. Previous research has shown that a small increase in temperature of frac fluid or water vapor creates a great number of micro fractures in shale, thus increasing the networks of interconnected gas and oil passageways in the shale mass. Use of any heating medium to enhance the production of standard fracking requires documentation of Pierre shale fundamental thermodynamic properties. A set of experiments were designed to find the specific thermodynamic and associated strain properties of Pierre shale that are crucial to Frac design. Specimens of shale were prepared and coated with a film of random paint particles for digital image correlation and strain measurement. Steam was used as a heat medium at alternating temperature and steam quality to create micro fractures in the shale with time. A compression machine was also used to apply load to a specimen, while the strain camera measured the strain across a face of the specimen in order to calculate Poisson’s ratio and Young’s modulus and other mechanical properties. The results of analysis of data showed that the specimen contracted in the X direction but expanded in the Y direction under applied uniaxial, compressive load. In this case, lateral strain is about 10% of the longitudinal strain. This is because it is easier to split the specimen parallel to its fissility planes than planes perpendicular to them. However, under the heat load, we observe that shale specimens exhibit two types of properties one auxetic and the other pseudo-elastoplastic properties. One particular example of an auxetic behavior is the prevalence of negative Poisson’s ratio. With the application of heat, it is possible to identify the progression of time and heat that converts the clays in the shale from one type to another. Another important lesson learned here is that alternating (cyclic) temperature and steam quality supplied to the specimen create a fatiguing effect, which makes fracture initiation and propagation processes faster. The graph of strain data versus time shows how the heat wave passes through the shale with specific frequencies as the specimen is exposed to heat load. Heating a water-saturated specimen creates heat transfer and measurable frequencies throughout the specimen. These frequencies buildup until the specimen’s fissility planes split apart, creating two and three dimensional fractures and micro fracture networks within the shale mass. This is, for example, similar to the lithotripsy technique used by physicians for breaking a kidney stone. Most importantly, we find that when two materials with a large difference in thermal conductivity like chert and clay are placed next to each other a great number of micro fractures develop at the boundary of the material with the highest thermal conductivity, i. e. chert. This is similar to observing loss circulation zones occurring at the contact boundaries of the sand and shale formations in drilling operations. We have calculated the resonance frequency of Pierre shale to be 1800Hz-2000Hz. Based on Fourier analysis of strain data, it is possible to create a model of frequency buildup behavior, which leads to fracturing of the shale. All of the data collected will be used as a basis for calculating porosity, permeability, and water saturation using heat energy as the input parameter.
