... and a least amount of proppants flowing back, optimization of a chock valve in operations is investigated. Furthermore, effects of a proppant size and well types including vertical and horizontal wells on chock valve adjustments are presented. A chock is adjusted by gradually increasing its diameter...

... for the basin that result in a significant reduction in the cost per bbl of oil produced. While geological parameters have been found to matter greatly for the production success of DJ horizontals, completions matter as well. The high GOR areas of Inner Core Wattenberg benefit most from jobs with more proppant...

... Abstract The key in unlocking unconventional reserves is to create massive fracture surface area. During the fracturing treatment, a huge volume of fracturing fluid is pumped to generate fractures and then followed with a large amount of proppant to provide enough conductivity for reservoir...

... model while a cohesive zone model is adopted to simulate the fracture propagation. A viscoelastic model is used to simulate the time-dependent fracture conductivity change due to proppant embedment. The synthetic cases are grouped into two categories: refracturing in existing perforations and in newly...

... behavior of fracture aperture due to changes in stress, resulting from rock stiffness and uneven distribution of proppants within primary and induced fractures, is investigated. Fractures are divided into three types, each with its own dynamic response to changes in stress. The impact of matrix...

Friction-reduction performance, proppant settling, viscosity, and coreflood studies were conducted with the following objectives: (1) investigate...
