... and retention time within the rock formation. It is well known that proppant is considered as one of the main additives in simulating unconventional wells, and its primary function is to maintain a conductive fracture during well production. Beyond that, it can serve as a matrix to deliver chemicals deep...

.... Meanwhile, the addition of 1.0 wt% AOS reduced the apparent viscosity of the hydraulic fluid to 0.56 cP. Higher viscosity is crucial to ease the flow of the hydraulic fracturing fluid to create the fractures and bring the proppant into the fractures created. The flow loop test showed that the hydraulic...

... Abstract Screenout of micro-proppants in narrow fractures is a significant issue for this emerging stimulation technique, however the predictive tools currently used in hydraulic fracturing simulators are inadequate. This work investigates screenout using numerical simulations. Data from...

... Abstract Hydraulic fractures can enhance well productivity from stress sensitive naturally fractured reservoirs such as coalbed methane or coal seam gas (CSG) reservoirs. Graded proppant injection (GPI) has been proposed to enhance long-term, far-field interconnectivity between the created...

... Abstract Clean water fracturing, where clean water is used as fracturing fluid, has the advantages of low damage and low cost. The proppant carrying capacity is a key factor for successful clean water fracturing treatment. Although a lot of experimental work has been carried out, the proppant...

Pumping data such as treating pressures, injection rates, and proppant concentrations were used to determine, in real-time, the number and type of fractures created during the hydraulic fracture treatment. This allowed for operational adjustments to be made to optimize pumping rate and proppant...

Despite this general trend, operators are constantly assessing the optimization of completions design to find the optimum stimulation and completion applications. This paper utilizes 3782...

... Abstract Hydraulic fracturing conductivity relies greatly on settled proppant size distribution and coverage area of the fracture. In low viscosity fluid systems, such as water or slickwater, dune structures are frequently deposited inside the fracture with proppant injected first landing near...

.... At a known pH, the results of stability were validated with the proppant pack glass column test and further verified with microscopic images. It was observed that adding SDBS to the hydraulic fracturing fluid keeps the coal fines well-dispersed in the post-hydraulic fracturing flow back and prevents coal...
