NEWS – December, 2007 EnSoCo performs Forensic GIS for IHS Energy As a demonstration of GIS capability for IHS Energy, EnSoCo was able to identify georeference and digitize well data based on a geodetically unidentified structure map in the Tampico production area of Mexico. The resulting deliverable was a fully digitized set of well data, including well ID, type and quantified WGS-84 location tied to high resolution satellite imagery. EnSoCo provided IHS with an ArcViewtm 9 map project, including well data and support culture. A Powerpoint presentation was generated outlining the processes performed, geodetic confidence and statement of well accuracy. An example of this project and before and after imagery is shown under Forensic GIS. NEWS – November, 2007 EnSoCo completes sale of its Geodetic Utilities to GXT Technology GXT Technology purchased two licenses of EnSoCo’s Geodetic Utility Suite of software. GXT follows sales to CGGVeritas, Seismic Exchange Incorporated (SEI) and Devon Energy as new licensees in 2007. A description of the utilities can be read and downloaded at EnSoCo Geodetic Utilities or by visiting the products page. John Conner ends a successful year as Chairman of the Americas Petroleum Survey Group Following a year (2006) as Vice-Chairman under Jim Cain, John served as Chairman of the organization in 2007. APSG, whose goals include education and best practice relating to geodesy and surveying in the oil and gas industry is supported by EnSoCo. John will continue to be involved in the APSG as a member of the technical advisory committee (TAC). John’s efforts in 2007 were aimed at increasing membership and involvement in APSG. EnSoCo awarded multiple OBC projects. EnSoCo is currently re-processing multiple legacy OBC projects for ExxonMobil. The projects involve surveys dating to the early 1980s and as recent as the mid 1990's. EnSoCo is applying direct arrival seismic picking technology to improve the accuracy of these older surveys. These surveys are follow on from a highly successful pilot project conducted in 2006. NEWS - June, 2007 EnSoCo completes position processing project for CGGVeritas Alaska. EnSoCo has just completed work for CGGVeritas in Alaska. EnSoCo provided personnel and processing capabilities for an OBC survey. EnSoCo provided position processing using its SRLS software for a combined marine and land survey. EnSoCo increases its office space. EnSoCo has recently added another 1500 sq. feet of office space adjacent to its current offices. The space was acquired to allow for continued growth in its GIS services business. Additionally EnSoCo has also been adding GIS personnel. EnSoCo has also entered into a marketing arrangement with Dave Clayton (DAC Consulting), who will provide marketing and business development guidance. Dave has been in the seismic industry for many years and recently retired from Input Output Corporation. EnSoCo awarded multiple legacy re-processing contracts. EnSoCo has recently completed two major legacy marine navigation re-processing projects for Veritas in the Gulf Of Mexico. EnSoCo incorporated its First Break picking technology to produce strengthened front end positioning as well as utilization of its proprietary pseudo compass streamer modeling. Approximately 25,000 sail kilometers of multi-vessel data were processed. EnSoCo have just been awarded two marine re-processing projects by Esso Australia involving a series of vintage surveys from the 1980's and early 1990's. These are follow up surveys to another project completed earlier this year. EnSoCo will apply enhanced editing, FBP technology and pseudo compass modeling to improve the accuracy on these older surveys. In addition to marine surveys, we have processed a number of legacy OBC and Bay cable surveys in the past year. EnSoCo continues to develop new processing technology to address legacy land, marine and transition zone positioning accuracy issues. To date EnSoCo have re-processed numerous legacy navigation surveys for improved imaging and for 4D baseline usage. EnSoCo offers GIS mapping and QC services. EnSoCo continues to expand its GIS services in support of Seismic positioning data management. EnSoCo is under long term contract with Devon Energy to provide positioning QC services of its navigation and positioning information from legacy land, marine seismic and well location data. EnSoCo has also been providing similar services under a joint venture project with Iron Mountain now in its fifth year on behalf of Anadarko Petroleum. These services also include large format digitizing and georeferencing of land, marine and TZ map data. Utilizing ESRI software, combined with proprietary EnSoCo software, we can provide extensive digital and hard copy analysis and translation of positioning data resulting in a fully QC'd and standardized data set ready for archive, processing or workstation usage. EnSoCo has completed development of a suite of Geodetic utilities aimed at the seismic and oil and gas industries. The utilities are Windows 2000 and Windows XP based and are fully compliant with the European Positioning and Survey Group (EPSG) codeing and naming conventions, while supporting bi-directional x,y to x,y with full single pass datum shift capability. Included are coordinate transformation and datum shift capabilities in both interactive and batchable file form. There is support for most industry positional exchange formats in and out, including SEG-P1, UKOOA P1 and SPS. This software is intended to be competitive with the Blue Marble suite of geodetic software at a competitive price. EnSoCo have developed these utilities over the past 25 years of its processing business. Beta releases of the utilities are being provided to select companies for comment and feedback. If you are interested in a more detailed description of the utilities or wish to be considered for Beta testing, please contact us. If you plan to re-process an older survey for purposes of enhanced seismic techniques, to perform time lapse, or for merging with adjacent or overlapping surveys please read the following: EnSoCo have considerable experience using new technologies to enhance the improvement of older 3D marine navigation surveys. Based on our knowledge in re-processing vintage surveys, as well as performing significant studies in degrading newer surveys to match earlier configurations we can and have dramatically improved the positioning for many surveys. By picking and incorporating seismic direct arrival data along with specialized vessel and in-sea dynamics modeling, we see improvements ranging from 15 to 30 meters at source and near trace. We have successfully incorporated direct arrivals in single cable surveys, removing offset and stretch uncertainty. Our psuedo compass modeling of compass data dramatically improves free-modeling of the streamers and reduces errors in mid and far trace positioning. Added to the solution algorithms are a vast array of batch and interactive editing and filtering tools which have been developed from over 20 years of processing marine towed streamer and more recently, ocean bottom seismic data. Combined with overwhelming support for proprietary and vintage recording formats, we can offer extremely fast turnaround in processing and at significant cost savings. We have a core group of staff with an average experience level of 15 years directly involved in processing navigation data. We offer this service for both towed streamer and ocean bottom seismic (cable and buoy) surveys. Please call or e-mail for a detailed write-up on the benefits of re-processing navigation data, which includes several examples of how we can improve the positioning and the seismic imagery. If the seismic is worth a second look, so is the navigation! |
