Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 47/09

US Classification:

16625012, 1662541, 1663051

Abstract:

The present disclosure relates to one or more apparatuses and methods to determine fluid movement within a formation. The apparatus includes a first packer configured to selectively engage a wall of a borehole of the formation, an outlet disposed adjacent to the first packer, wherein the outlet is configured to pump a first fluid therefrom and into the formation, and a detecting tool configured to detect the first fluid within the formation. Movement of the first fluid may be determined based upon the detection of the first fluid within the formation.

Abstract:

An apparatus, system, and method are provided for receiving requirements information from a user via a web browser. The request and the requirements information are received by a web server and forwarded to a correlation engine. The correlation engine is operatively connected to, among other things, a catalog database listing various products that are available to the user, a pricing database that contains price information for a plurality of the products, an advisor database that contains feature information about the products, and a client relationship manager that retains information about the user. The correlation engine correlates the data from the various database through appropriate function modules in order to determine which product best suits the user's requirements based on price, availability, and feature set. The user is presented with a coherent set of choices and is thus enabled to select one or more items from those choices to consummate a sale for the products.

International Classification:

E21B 43/24

US Classification:

166246, 1662723, 166 52

Abstract:

Embodiments of the invention described herein relate to methods and apparatus for recovery of viscous hydrocarbons from subterranean reservoirs. In one embodiment, a method for recovery of hydrocarbons from a subterranean reservoir is provided. The method includes drilling an injector well to be in communication with a reservoir having one or more production wells in communication with the reservoir, installing casing in the injector well, cementing the casing, perforating the casing, positioning a downhole steam generator in the casing, flowing fuel, oxidant and water to the downhole steam generator to intermittently produce a combustion product and/or a vaporization product in the reservoir, flowing injectants to the reservoir, and producing hydrocarbons through the one or more production wells.

Abstract:

Embodiments of the invention described herein relate to methods and apparatus for recovery of viscous hydrocarbons from subterranean reservoirs. In one embodiment, a system for recovering hydrocarbons comprises a downhole steam generator for coupling with a packer in an injector well, an umbilical device coupled to the downhole steam generator for lifting or lowering the downhole steam generator in the injector well, a first shear point disposed between the downhole steam generator and the packer, and a second shear point disposed between the umbilical device and the downhole steam generator, wherein the first shear point has a shear strength that is different than a shear strength of the second shear point.

Assignee:

World Energy Systems Incorporated - Forth Worth TX

International Classification:

E21B 44/00

US Classification:

16625001, 166 53

Abstract:

A system and method of measuring and controlling the operation of a downhole steam generator. The system may include surface and/or downhole control systems for sending and/or receiving control and measurement signals. The control systems may also communicate with and control surface and/or downhole equipment for supplying process fluids, gasses, and/or mixtures to the downhole steam generator. The control system may control operation of the downhole steam generator by storing, processing, and/or analyzing measured data corresponding to one or more downhole steam generator operations and/or one or more field, formation, reservoir, or other operating objective.
