... Abstract A case study has been conducted on 90 gas wells in West Texas and 3 gas wells in northern Alberta to improve fracture, conductivity and post fracture productivity. This study shows the effectiveness of various treatment designs and breaker systems. These wells have shown improved...

... a propped fracture with adequate fracture conductivity. The fracture conductivity is influenced by the reservoir environment following a hydraulic fracturing treatment. Many years of field experince have shown that it is usually necessary to used a gelled fluid to create fracture width and suspend...

... parameters. These factors are: effect of clean-up of fracturing fluid, tail- in, changing conductivity inside the fracture as function of position and time, fracture height, and low fracture conductivity. Effect of producing time is also discussed. Numerous field examples are cited, pre- senting both...

... convenient to use. Synthetic and field examples are given to illustrate the utility and limitations of this method. Fracture half-length and fracture conductivity are determined from the post-fracture buildup when formation permeability or initial pressure is known. Introduction The theory of fluid flow...
