2007 02 27 Fiber Optic Sensing Systems for SAGD & Reservoir MonitoringTuesday, February 27, 2007 Nexen Annex (+15 level) InvitationLxSix Photonics Inc. along with PTAC Petroleum Technology Alliance Canada, and event co-sponsor Nexen invite you to attend a Technical Information Session to review the specifics of a project for the development of best practices for improved reservoir production efficiencies using the LxIQ™ fiber optic sensing systems. The project includes the capture of temperature measurements from permanently installed LxIQ™ sensors and the analysis of this information through the use of third party reservoir management software to perform the following tasks;
BackgroundIt has been generally recognized that fiber optic DTS-"Distributed Temperature Sensing"-technology offers a great potential for field applications in the oil industry. However, it also has some severe limitations in high temperature SAGD applications due to its limited power budget and dynamic range. In the hydrogen rich and high temperature environment of SAGD reservoirs, fiber degradation results in high losses making conventional DTS fiber fail prematurely. This results in the operator having to replace the DTS fibers often. In contrast to this, LxSix has developed the LxIQ™ optical fiber Bragg grating (FBG) temperature measuring system, which measures and compensates for the hydrogen darkening effects. Laboratory aging studies have predicted that the LxIQ™ will operate in harsh environments for up to 7 years. This translates to enormous operational savings as well as the benefits from accurate temperature measurement, which can result in up to 20% recovery improvements from the well. This multipoint fiber optics based sensing cable for SAGD applications is designed to provide continuous temperature measurements in harsh environments and up to temperatures of 275°C. The early-time performance and rapid heating of the near-wellbore region to allow gravity drainage are essential operational aspects of SAGD. The goal of any early-time procedure in SAGD should be to heat the near-wellbore area as uniformly as possible. After these conditions have been initiated, the SAGD process allows for continuous steam chamber growth and oil production. The LxIQ™ as an in-situ, multi-point temperature measurement system is an effective reservoir tool providing real time temperature data to optimize efficiency and production rate, as well as to ensure improved early-time performance (heat-up phase) through the use of uniform temperature management. CALL FOR PROJECT PARTNERSLxSix is interested in field testing and maturing this exciting technology, and wishes to collaborate with interested SAGD operators, reservoir modeling software developers, engineering and consulting firms, as well as service and field installation companies. It is expected that the partnering companies will provide test wells, equipment, know-how and/or manpower to instrument a SAGD well with the LxIQ™ system. The ultimate goal of this project is to jointly develop best practices and on-line operating models to optimize the efficiency of SAGD operations-particularly the Steam Oil Ratio and other relevant parameters including the reduction of the steam chamber operating pressure. The project will include the following steps:
The project to capture, analyze and to develop the optimal recovery formula should be completed within 2 years. THE OPPORTUNITYThe participants' fee will include an upfront amount of $50,000.00 or in-kind contributions of equipment and/or manpower for field testing. LxSix will provide to the Operators who make this up front financial contribution a credit towards the purchase of the OMG™ optical fiber cable. The knowledge acquired and the best practices developed from the project will be shared with all partnering participants. Who Should Attend
