... Abstract Plug failures, sub-optimal stage design and variable proppant distribution across multi-cluster stages are common issues experienced during plug and perforate hydraulic fracturing. When one or more of these problems occur production potential can be significantly reduced. This case...

... the lack of hydraulic width were considered: increase in gel loading, increase in pumping rate, optimizing pad volume, changing completion strategy, reducing job size, reducing proppant concentration, etc. After thorough consideration, it was found that removing the larger proppant might be an optimum...

... with the initial post-frac performance during the cleanup period, consistent with the effect of multi-phase non-Darcy flow. Resin Coated Proppant (RCP) was used in two of the wells, and may have had a negative effect on the initial production (choke or mechanical skin effect) as described in a previous publication...

... exposed the equipment and material to aggressive environment. Hydraulic fracturing operations were carried out smoothly with the support of a dedicated frac vessel reaching up to 10,000 psi at wellhead and more than 12,000 psi at bottomhole. The total amount of proppant pumped into formation was one...

Extensive reviews were done using multi-disciplinary approach to assess the feasibility of proppant frac treatment in tight carbonate reservoirs. Integration of FMI data, geo...

... Abstract In proppant stimulation treatments, when high fluid leak-off and low fluid efficiency is encountered, typically the first measure taken in job redesign is to increase the PAD volume and pumping rate to mitigate fracture width reduction. These measures will adversely affect the job...
