Sustainable Hydrocarbon Recovery in Unconventional Reservoirs

The University of Kansas

The University of Kansas (KU) is launching a new Joint Industry Project (JIP) in Sustainable Hydrocarbon Recovery in Unconventional Reservoirs. Researchers from the Chemical & Petroleum Engineering Department (CPE), Tertiary Oil Recovery Program (TORP), Civil, Environmental, & Architectural Engineering Department (CEAE), and the Department of Geology (GEOL) are working together to develop novel technologies to address issues of critical importance for sustainable unconventional reservoir exploitation. The JIP will explore four Thrust Areas, each led by a Principal Investigator (PI).

Thrust Area 1: Produced Water Treatment

PI:            Dr. Karen Peltier (TORP) (kpeltier@ku.edu, 785-864-2912)

Co-PIs:   Dr. Steve Randtke (CEAE) (srandtke@ku.edu), Dr. Belinda Sturm (CEAE) (bmcswain@ku.edu), Dr. Edward Peltier (CEAE) (epeltier@ku.edu)

Team:      post-doctoral associate (1), field liaison engineer (1)

  • Removal of naturally occurring radioactive materials (NORMs) and scale-causing minerals using nanotechnology – using polyelectrolyte complexes as nanosized entrapment agents to target metals such as barium, strontium, and radium directly in produced water. Once formed, these nanoparticles can be separated from the produced water through filtration or gravity separation, and may be regenerated for additional use.
  • Application of fluidized bed biological reactors for organics removal – increasing contact between organic chemical contaminants and reactor components (microbes) using fluidized beds to increase the reaction rate, enabling the processing of large volumes in minimal space.

Thrust Area 2: Hydraulic Fracturing in Shale Formations

PI:            Dr. Reza Barati (C&PE) (rezab@ku.edu, 785-864-1232, http://people.ku.edu/~rezab/)

Co-PI:     Dr. Anil Misra (CEAE) (amisra@ku.edu), Dr. Jyun-Syung Tsau (TORP) (tsau@ku.edu)

Team:      graduate research assistant (2), undergraduate research assistant (1), field liaison engineer (1)

  • Nano-proppants for hydraulic fracturing of shale formations – using nano-proppants capable of packing micro-fractures to prevent fluid loss and improve both effective fracture length and productivity of the fractured wells.
  • Nanoparticle-stabilized CO2-foam as fracturing fluids – fluid loss and fracture cleanup properties of CO2-foam as fracturing fluid will be studied for different nanoparticles and chemicals to be used in optimization of fluid properties.
  • Effects of produced water composition on fracturing fluid efficacy – identifying the levels below which chemical contaminants need to be reduced in order for reuse to be attractive to the producer. This work will be performed in conjunction with our produced water treatment activities and will initially focus on fracturing fluids.
  • Improved fracture propagation model – developing robust models capable of modeling fracture propagation in a variety of litho-facies, including in brittle or semi-brittle formations with natural fractures.

Thrust Area 3: Enhanced Oil Recovery in Shale Formations

PI:               Dr. Jyun-Syung Tsau (TORP) (tsau@ku.edu, 785-864-2913)

Co-PI:         Dr. Reza Barati (C&PE) (rezab@ku.edu)

Team:         graduate research assistant (1), undergraduate research assistant (1), field liaison engineer (1)

  • Gas injection to enhance oil recovery from shale formations – studying the feasibility of using different gases with huff-n-puff process to improve oil recovery in tight shale formations. Preserved core samples from target shale formation will be used to examine key parameters to the effectiveness of the process.  Experimental investigation and computer modeling will be used to improve understanding of the complexity of phase behavior and the flow behavior in shale rock for optimization of the oil recovery. Initial focus will be on CO2 due to its favorable solvation property. Other gases will be evaluated later. 

Thrust Area 4: Reservoir Characterization and Simulation

PI:            Dr. Reza Barati (C&PE) (rezab@ku.edu, 785-864-1232,  http://people.ku.edu/~rezab/)

Co-PI:     Dr. Jyun-Syung Tsau (TORP) (tsau@ku.edu), Dr. George Tsoflias (GEOL) (tsoflias@ku.edu)

Team:      graduate research assistant (2)

  • Improved reservoir characterization – using improved correlations between seismic data and fracture properties, develop a more representative fracture network/property model for shale reservoirs capable of adjusting the fracture spacing based on the fracture characteristics of the reservoir
  • Reservoir modeling – developing a small scale model for production from a naturally fissured shale block that captures the full physics behind the shale gas or oil production. This model will then be extended to gas injection application and reservoir scale models
  • Production optimization for shale oil/shale gas-  investigating various drilling, fracturing and injection scenarios to improve production from ultra-tight, organic rich unconventional reservoirs
  • Seismic methods for production optimization – develop seismic technology for optimizing production of unconventional reservoirs. Assess surface seismic methods, multi-component, time-lapse and borehole micro seismic monitoring. Conduct pilot characterization study of the Chatanooga shale in South-Central Kansas.
