20100276197 | MEASUREMENTS WHILE DRILLING OR CORING USING A WIRELINE DRILLING MACHINE - A drilling system and method for drilling underground boreholes is provided. The drilling system comprises a tool body, a downhole motor, a drill bit mounted on the body to be driven by the motor, a mechanism for driving the tool body axially along the borehole so as to apply weight on the drill bit when drilling, and an electrical cable extending from the surface to the tool body to provide power for the drilling motor. The tool body includes a conduit connected to the drill bit such that drilled material passes from the drill bit through the conduit, and sensors are provided in the conduit for measuring properties of the drilled material. | 11-04-2010 |
20110060572 | DYNAMIC SUBSURFACE ENGINEERING - An example system includes interconnected modeling modules that share knowledge to create a unified earth model dynamically representing a subsurface site. The system models and may simulate subsurface operations associated with, for example: hydrocarbon production and stimulation, natural gas storage, carbon capture and storage, aquifer maintenance, geothermal energy production, and in-situ leachable ore processing. The system integrates a reporting module, and also an economic module to evaluate cost versus benefit of each subsurface operation. A related example method for performing subsurface engineering includes generating a model of a subsurface site including a geological horizon, obtaining an offset relative to the geological horizon, and locating an operation based on the offset. When field data update the model in real time, positions of 3D objects and 3D surfaces are dynamically updated in the model, including the positions of the modeled operations. | 03-10-2011 |
20120297928 | HEAP LEACH OPERATIONS - A method of heap leaching including forming a heap lift, installing a horizontal solution collection system between the heap layers including a horizontal tubing with a wireline data collection tool disposed therein, providing a heap leach model for modeling the heap leach operation including a solvent formulation and a irrigation setting, obtaining collected data from the wireline data collection tool while irrigating the heap lift, the collected data including in-situ material parameters of the heap layers and in-situ solution parameters of the solution flowing in the heap layers, modeling the heap leach operation using the collected data based on the heap leach model to generate a result, and adjusting the heap leach operation based on the result. | 11-29-2012 |
