... Abstract Recovery of frac-pack fluids is often poor in offshore operations. Large amounts of stimulation fluids left in the fracture may leak-off into the porous formation or block part of the proppant pack thus impairing hydrocarbon production. A typical frac-pack treatment fluid contains...

... fracturing fluids. The average molecular weight of treated fluids was measured by changes in intrinsic viscosity. Additionally, regain conductivity measurements were carried out. Results showed an 84% regain conductivity in proppant packs. Chlorophyll-treated cross-linked fluids showed a more than 90...

... Abstract Polymer gels used in hydraulic fracturing to generate fracture geometry and ensure proppant transport are also known to damage the proppant pack permeability, and this damage reduces the well production rate. As reuse of produced water and other highly saline water sources...

... viscosity must be reduced and the broken fluid flowed back through the proppant to the wellbore. This process should occur with minimal damage to the proppant pack so as not to restrict hydrocarbon production from the reservoir. Significant permeability damage to the proppant pack occurs if insoluble...

... into the target fractures, or creating operational issues if removal of the proppant from the wellbore is required. As another option, proppant can be coated with a tackifier polymer to maintain propped fracture conductivity by mitigating migration and intrusion of formation particulates into the proppant pack...

... based on a naturally low residue polymer that, when breaking, causes significantly less damage to the formation and proppant pack compared to conventional guar-based fracturing fluids. Since its introduction, guar-based fluid technology has grown to dominate the hydraulic fracturing industry because...

Selection of the appropriate proppant flowback control technology is made with consideration of engineering factors such as fluid compatibility issues, setting time, resistance to cycling stress-loading issues, and conductivity...

... or unconsolidated formation sands or loose proppant packs. Consolidation strengths and scanning electron micrographs of the treated formation sand or proppant packs were analyzed to identify the mechanisms behind the treatment fluids in providing cohesion between particulates and how the pore channels within a pack...

... Abstract Realistic laboratory simulation of fractures propped with sand, engineered ceramic proppants, and resin-coated proppants to determine the impact of temperature, stress, and stress cycling on proppant-pack structure and pack permeability is both difficult and expensive. Large...
