20100018303 | PERMANENTLY INSTALLED IN-WELL FIBER OPTIC ACCELEROMETER-BASED SENSING APPARATUS AND ASSOCIATED METHOD - Embodiments of the present invention include a fiber optic seismic sensing system for permanent downhole installation. In one aspect, the present invention includes a multi-station, multi-component system for conducting seismic reservoir imaging and monitoring in a well. Permanent seismic surveys may be conducted with embodiments of the present invention, including time-lapse (4D) vertical seismic profiling (VSP) and extended micro-seismic monitoring. Embodiments of the present invention provide the ability to map fluid contacts in the reservoir using 4D VSP and to correlate micro-seismic events to gas injection and production activity. | 01-28-2010 |
20100078164 | PERMANENT DOWNHOLE DEPLOYMENT OF OPTICAL SENSORS - The present invention involves methods and apparatus for permanent downhole deployment of optical sensors. Specifically, optical sensors may be permanently deployed within a wellbore using a casing string. In one aspect, one or more optical sensors are disposed on, in, or within the casing string. The optical sensors may be attached to an outer surface of the casing string or to an inner surface of the casing string, as well as embedded within a wall of the casing string. The optical sensors are capable of measuring wellbore parameters during wellbore operations, including completion, production, and intervention operations. | 04-01-2010 |
20110280103 | SONIC/ACOUSTIC MONITORING USING OPTICAL DISTRIBUTED ACOUSTIC SENSING - Methods and apparatus for performing sonic well logging within a wellbore based on optical Distributed Acoustic Sensing (DAS) are provided. A sonic well logging system based on DAS may be capable of producing the functional equivalent of tens, hundreds, or even thousands of acoustic sensors. In this manner, the emplacement of the sonic well logging system based on DAS may not be nearly as complex or expensive as emplacing a sonic well logging system based on traditional methods. Furthermore, multiplexing may be simpler, downhole electronics need not be used, and the sonic well logging system may be used in extreme, high temperature environments. | 11-17-2011 |
20120092960 | MONITORING USING DISTRIBUTED ACOUSTIC SENSING (DAS) TECHNOLOGY - Methods and systems are provided for performing acoustic sensing by utilizing distributed acoustic sensing (DAS) along a length of a conduit, such that the sensing is performed with the functional equivalent of tens, hundreds, or thousands of sensors. Utilizing DAS in this manner may cut down the time in performing acoustic sensing, which, therefore, may make acoustic sensing more practical and cost effective and may enable applications that were previously cost prohibitive with discrete acoustic sensors. | 04-19-2012 |
20120111104 | FIBER OPTIC CABLE FOR DISTRIBUTED ACOUSTIC SENSING WITH INCREASED ACOUSTIC SENSITIVITY - Methods and apparatus for performing Distributed Acoustic Sensing (DAS) using fiber optics with increased acoustic sensitivity are provided. Acoustic sensing of a wellbore, pipeline, or other conduit/tube based on DAS may have increased acoustic sensitivity through fiber optic cable design and/or increasing the Rayleigh backscatter property of a fiber's optical core. Some embodiments may utilize a resonant sensor mechanism with a high Q coupled to the DAS device for increased acoustic sensitivity. | 05-10-2012 |
