... of 750 m horizontal well projects will start late 1999. The SAGD process is a simple process. It consists of two horizontal wells, an injector placed directly above a producer. Both wells are at first heated by steam circulation. When a communication between two wells is established, steam...

... Abstract It is a well-known fact in the petroleum industry that thermal treatment (wellbore heating) could result in significant benefit to the producing wells by remedying fluid related problems. Recently, it bar been shown in the literature that thermal stimulation also improves fluid flow...

... of Colorado shale near a cased wellbore due to heating. The temperature, pore pressure and stresses response in Colorado shale near a cased wellbore due to heating are analyzed using a coupled thermal-mechanical-hydraulic solution. The possibility of failure or fracturing of the shale due to heating...

...-56-2W4) and one horizontal well (16D-25-56-2W4) where connected electrically and heated. This paper presents an overview of electrically heating a horizontal well with vertical wells, the design of the electrical heating system, operational experience, test data, and a discussion on the successes...

... Abstract Gravity flow plays an important role in thermal oil recovery under a variety of conditions. These include cyclic steam stimulation, conduction heating and formation heating in a fractured system. This paper addresses first the problem of steam heating of a naturally fractured...

... Abstract Near well-bore electromagnetic heating is a relatively new process designed to reduce oil viscosity and result in improved well productivity. To date most of the tests have been conducted in widely spaced vertical wells. The Texaco Frog Lake Project will determine the applicability...

... Abstract In an effort to develop a novel recovery technique for tar sand reservoirs of Ugnu in Alaska, electromagnetic heating using horizontal well is proposed. One of the bigger technical problems with thermal injection on the' North Slope is the large permafrost region. The permafrost...

... following each other without heating of the oil bearing layer start temperature of high velocity oxidation in this mixture was 30 ° C. For heterogeneous reservoirs a single slug mixture, combined with low heating rate was investigated. The combined ignition technology was studied in radial model of the near...

... economically against this projected price scenario for natural gas heating. These economic comparisons were made on a consistent present worth basis for several solar system designs against a conventional natural gas heating system. The results indicate a clear economic advantage continues for conventional...
