... Abstract A 3-D physical model has been developed to investigate the Combustion Override Split-Production Horizontal well (COSH) process. The 3-D model was rectangularbox with I8 cm by 54 cm by I2 cm dimensions. The vertical well was used as anair injection well and top horizontal well was used...

... conformance in injection wells. Acid stimulations have been used since the 1940's as a means of improving production, with the first acid fracturing treatments being pumped in the late 1980's. Beginning in I996, these two technologies were combined in an attempt to successfully increase oil production from...

... such as petroleum hydrocarbons are most suitable for treatment with bioventing (5). Bioventing systems vary depending on unique site and contaminant conditions. The simplest layout is composed of an air injection well only. Other systems may include an air injection well into the contaminated soil...

Introduction Steamflood operators are using insulated tubing in an increasing number of steam injection wells to reduce heat loss or in some cases to protect low grade casing from excessive thermal stress. Wells in Canada the United States and Venezuela are now equipped with over 400,OOO feet of insulated...
