Searching for the root cause of shale well rate variance: Highly variable fracture treatment response
TUĞAN, MURAT FATİH; Weijermars, Ruud (2022-03-01)
This case study highlights that shale wells drilled with tight well spacing in the same landing zone using the same fracture treatment plan, commonly show large variance in well productivity. Searching for the root cause(s...
Application of TGA-MS technique for oil shale characterization and kinetics
Kök, Mustafa Verşan; Varfolomeev, Mikhail A.; Nurgaliev, Danis K.; Kandasamy, Jayaraman (2022-03-01)
Thermal characteristics and model free kinetics of four different oil shale samples were studied using simultaneous thermogravimetry-mass spectrometer (TGA-MS) analysis performed at three different heating rates and under ...
Fluid-CO2 injection impact in a geothermal reservoir: Evaluation with 3-D reactive transport modeling
AKIN, TAYLAN; Baser, Ali; Saracoglu, Onder; Akın, Serhat (2022-01-01)
Geothermal energy is commonly recognized as an environmentally friendly source of energy. However, geothermal fluids have unusually high CO2 content, particularly, in carbonated geothermal reservoirs. An efficient method t...
Numerical Modeling of Waterflooding Experiments in Artificially Fractured and Gel Treated Core Plugs by Embedded Discrete Fracture Model of a Reservoir Simulation Toolbox
Kaya, Onur Alp; Durgut, İsmail; Canbolat, Serhat (2022-01-01)
© 2022, Society of Petroleum Engineers.The fluid flow dynamics of the matrix and fractures are significantly different from each other. Fractures are high-permeability flow channels that serve as the main flow units. On th...
Nanoparticle-stabilized CO2 foam to improve conventional CO2 EOR process and recovery at Bati Raman oil field, Turkey
Safran, S. Esra; Kök, Mustafa Verşan (2022-01-01)
(B.Raman), which is the largest oil field of Turkey's already existing CO2 injection system, does not produce at the desired efficiency due to the natural fracture characteristics. Therefore, this research is performed to ...
