20080201080 | DETERMINING FLUID AND/OR RESERVOIR INFORMATION USING AN INSTRUMENTED COMPLETION - To determine fluid flow information associated with a well, data from plural discrete temperature sensors in zones without radial fluid flow in the well are received. The fluid flow information associated with the well is derived by combining the received data from the plural discrete temperature sensors with reservoir data that is independent of the fluid flow. That information can be further enhanced by monitoring the changes of temperature data over time. | 08-21-2008 |
20080236837 | COMMUNICATING MEASUREMENT DATA FROM A WELL - To communicate measurement data from a well, data corresponding to measurement data collected by multiple sensors in a well is transformed downhole and passed to an intermediate communications device, which device in turn passes a subset of that data to a destination communications device. The destination communications device applies a second transformation to the data received from the intermediate communications device. The first and second transformations are designed such that meaningful data can be recovered at the destination communications device even though only a subset of the original transformed data has been received. | 10-02-2008 |
20090066535 | ALIGNING INDUCTIVE COUPLERS IN A WELL - An apparatus that is usable with a well includes a first equipment section that includes a first inductive coupler and a second equipment section that includes a second inductive coupler.
