20130241742 | Data Retrieval Device for Downhole to Surface Telemetry Systems - A data retrieval device for communicating between a downhole location within a wellbore ( | 09-19-2013 |
20100294491 | CLEANUP PRODUCTION DURING SAMPLING - Cleanup monitoring and prediction in real time targeting estimation of pumpout volume versus final contamination, including detecting breakthrough of formation fluid to a sampling tool and detecting transition of cleanup regime from a predominantly circumferential cleanup regime to a predominantly vertical cleanup regime. Similar workflow can be employed for estimating contamination at the end of cleanup production for a given pumpout volume. | 11-25-2010 |
20100127888 | USING POCKET DEVICE TO SURVEY, MONITOR, AND CONTROL PRODUCTION DATA IN REAL TIME - A system for real-time data surveillance in an oilfield operation includes a data collection system deployed at a well site for collecting oilfield data; an office-based computer system for storing and analyzing the oilfield data; a portable device, wherein the portable device includes at least one program for communicating with the office-based computer system, for surveying the oilfield data stored in the office-based computer system, and for causing the office-based computer system to perform a process implemented on the office-based computer system; and a communication system providing communication links among the data collection system, the office-based computer system, and the portable device. | 05-27-2010 |
20090038392 | SYSTEM AND METHOD FOR CORRECTING ERRORS IN DEPTH FOR MEASURMENTS MADE WHILE DRILLING - A method and system is disclosed for automatically correcting for depth errors in measurements taken from a drill-string during the drilling phase of the construction of a hydrocarbon wellbore. The correction is based on a stress profile which in turn is based on the states of the drilling rig, drill string description length spec, borehole description trajectory, friction factor and weight on bit. | 02-12-2009 |
