..., and pumping schedule, uneven distribution of fluid and proppant among fractures connected to different perforation clusters can be defined by wellbore proppant transport hydrodynamics, fracture propagation mechanics, or a complex interplay of both. A modeling case study exploring strategies to mitigate...

... Abstract Downhole imaging technology has been widely utilized in recent years to help diagnose proppant distribution during hydraulic fracturing operations. Abrasion leading to entry hole enlargement provides strong evidence of proppant placement into individual perforations, and treatment...

... proppant flowback control. Improved fracture geometry and proppant flowback prevention were identified as key elements for the success of the fracturing campaign in these mature fields. Fracturing channel technique was implemented to generate higher fracture conductivity in a low reservoir pressure...

... erosional pattern observed in the field is presented. Throughout this work, six different hydraulic fracturing completion parameters are investigated to determine the respective roles in perforation erosion. The six parameters include proppant size, proppant concentration, proppant sphericity, fracturing...

... variation in the perforation entry hole by establishing uniformity in gun clearance and angle of incidence of the perforation jet at the wall of the casing, oriented perforating has been shown to minimize the tendency of proppant to separate from the fracturing fluid while travelling across the perforated...

... Abstract Unlike high-viscosity fluids, proppant transport with slickwater inside fractures is complex, but most fracture models do not adequately describe it. These models solve proppant transport based on simplified continuity equations. They assume that the average proppant velocity...

... Abstract Our goal in this paper is to quantify the impact of proppant settling in the wellbore on the efficiency and distribution of proppant into perforation clusters. This phenomenon has been experimentally studied on the lab scale in the past but no field-scale simulations have been...

... Abstract The American Petroleum Institute testing Standard 19-D (2008) is the current industry standard for conductivity testing of proppants used in hydraulic fracturing. Similar to previous standards from both the API and ISO, it continues the practice of measuring a "reference" conductivity...

.... N2 fracs are uncommon in modern completions but provide numerous benefits for operations in the San Juan Basin. Benefits of N2 foam fracs include reduced water usage, less proppant settling (improved carrying capacity of proppant), and less parent/child interference. The N2 fluid is high-viscosity...

... of microproppant in the fracture design, which was deployed in a multi-well field study and shown to improve production, and is the subject of this paper. As the industry continued to move to smaller size proppant, microproppants have been introduced as another potential improvement in the fracture design...

... Abstract A growing number of hydraulic fracturing stimulation treatments rely solely on the deployment of 100-mesh (i.e. 150μm) proppant. Further, these may be preceded by post-pad injection of microparticles (i.e. 5-75μm) with the intent of activating natural fractures. The objective...
