... 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...

Paper Number: SPE-180243-MS
... 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...

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...
