... to the surface. The process operates in a gravity stabilised manner by restricting drainage to a narrow mobile zone. This causes the flow of mobilised fluids to enter directly into the exposed section of a horizontal production well. The process can be operated on primary production, as a new technology...

.... The methods were ranked based on a set of criteria including logistics and engineering challenges of water treatment and processing in the arctic, environmental regulations, costs of installation, operations and maintenance. We conclude that surface discharge by use of ground sprinklers is not acceptable...

Introduction The CSS process as operated by Imperial Oil is described in the application (1) to the Alberta Energy Utilities Board (EUB) for expansion of the Cold Lake Project which was submitted in February 1997...

... with steam from the early period of a SAGD operation. This is because most of the injected gas gathers at the upper part of the leading edge of the steam chamber and prevents the growth of steam chamber there, which results in a reduction of ultimate oil recovery. However, if the gas injection is initiated...

... Abstract The Wizard Lake D-3A Pool has been undergoing a tertiary hydrocarbon miscible flood (HCMF) since 1983 after completing primary production (1951–1967) and a secondary HCMF (1969–1983). The operation is comprised of three solvent injectors, four push gas injectors and 42 production...

... Abstract A procedure is described that allows an operator to identify artificial lift wells which are operating inefficiently. A logical sequence of steps is presented for acquiring performance data such as casing annulus fluid level, casing pressure, bottomhole pressure, dynamometer analysis...

The prototype system was tested over a broad range of operating parameters, and it was found the Gas Recovery/Recirculation System appears to be technically and operationally feasible...
