Hydraulic fractures have become a common stimulation application in the oil and gas industry, especially in tight formations. Published models assume the hydraulic fractures are vertical and symmetric. However, recent studies have shown that fractures are asymmetric and inclined with respect to the vertical direction and the axis of the wellbore. ...

Introduction In 1989 the EPA promulgated the Surface Water Treatment Rule (SWTR) in response to the 1986 Amendments to the Safe Drinking Water Act (SDWA). The overall goal of the SWTR is to protect consumers from pathogens. The SWTR recommends a multiple-barrier approach including source water protection, filtration and disinfection when surface ...

Directional Technologies Is The Expert At Horizontal Soil Vapor Extraction   A horizontal soil vapor extraction well and two horizontal air sparge wells rapidly remediate contamination in situ under a research and development facility. These horizontal wells were installed by environmental directional driller Directional ...

Introduction Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. These ...
