...Sonic Scanner Logs Young's modulus and Passion's ratio were obtained from the sonic scanner log measurements ( El Sgher et al., 2021c ). Diagnostic Fracture Injection Test (DFIT) Instantaneous Shut-in Pressure (ISIP), Closure Pressure (P c ), Process Zone Stress (PZS) were determined...

... Abstract Slickwater-sand fracturing design is widely employed in Marcellus shale. The slickwater- sand creates long skinny fractures and maximizes the stimulated reservoir volume (SRV). However, due to the fast settling of sand in the water, lots of upper and deeper areas are not sufficiently...

...Orienting the lateral Horizontal well production benefits by orienting the well in a direction parallel to the minimum principal horizontal stress such that the induced hydraulic fractures grow parallel to the maximum horizontal stress during completion ( Zinn et al., 2011...

... Abstract Low injected fracturing fluid recovery has been an issue during flowback period that is highly impacted by the fracture closure behavior. Although existing flowback models consider fracture closure volumetrically, they do not represent the true situation of non-uniform fracture closure...

... The modern completions in the TMS have all been plug & perf completion designs. The explosive energy during perforating should induce micro-cracks from the perforations. When fracturing fluid is forced to go through the perforations, multiple fractures may be initiated from the micro-cracks...

... is constant and the temperature in the formation remains constant. Hydraulic fractures or micro fractures are finite conductivity and the flow within the formation or fracture observes the Darcy law. Wellbore storage and skin effect are considered. Abstract Due to the complexity of shale...

...Criteria for Selecting Candidate Reservoirs for CTTHF Abstract Complex Toe-to-Heel Flooding (CTTHF) is a short distance flooding technique developed by the authors for sandstone formations. CTTHF applied on horizontal wells and requires at least one barrier and injector hydraulic fracture...

... Benefited from the efficiency of hydraulic fracturing and horizon drilling, production of unconventional oil and gas has grown rapidly in the past decades, making a great contribution to hydrocarbon production in North America ( Boyer 2007 ; King 2010 ). Although EOR methods increased production...

... fracture(s). Additionally, helium was injected into the core samples at four different pressures (100 psi, 200 psi, 300 psi, and 400 psi) to determine the optimal pressure for porosity measurements. Complex Transient Method was employed to measure the permeabilities of the core samples. Ultrasonic velocity...

... Each fracture is modeled as a high permeability rectangular group of cells characterized by a fracture length and fracture height. The permeability and porosity of the blocks representing the fracture are derived so they are consistent with the specified fracture conductivity and porosity using...

... Abstract In the past ten years, hydraulic fracturing technology and strategies have made major improvements in the operational efficiency and economic performance of shale well completions. Much of this advancement was derived in the past three years as a response to the global downturn in oil...

The observation of crossflow among fractures has been...

... Abstract During the hydraulic fracturing process, the rough surface of fractures and the viscous proppant suspension flow bring great challenges to the distribution of proppants evenly at the fracture thin apertures. As a result, a detailed understanding of the effect of surface roughness...

... The process of fracturing requires thousands of gallons of water based fracturing fluid to be pumped into the formation and most of the time more than 70% of the fluid gets trapped in the reservoir and fracture matrix. This increases the irreducible water saturation in the matrix, reducing...
