Guralp Delivers Life of Field Micro-seismic Monitoring System to Kashagan

  Today Guralp Systems announced the delivery of a life of field seismic monitoring system to the Kashagan field. The Kashagan field is located in the Kazakhstan zone of the Caspian Sea and is one of the world’s largest discoveries in the last 30 years. Located in the northern extremities of the Caspian Sea, the water depth varies between 3m and 10m. The field is part of the North Caspian Sea Production Sharing Agreement (NCSPSA) operated by North Caspian Operating Company (NCOC) on behalf of a consortium consisting of KazMunayGas, ENI, Shell, ExxonMobil, Total, ConocoPhillips, and Inpex. A Shell / KMG joint venture, named NCPOC, has responsibility for NCSPSA production operations, of which the first phase will be from the Kashagan field. Guralp is to supply a life of field monitoring system to NCPOC, which comprises eleven CMG-3T borehole instruments. Each instrument houses a three component broadband seismometer capable of detecting low frequency seismic events down to 0.03Hz. Six instruments are located in boreholes close to the coast on the mainland of Kazakhstan, whilst the other five are located in boreholes drilled in the offshore artificial islands constructed specifically for producing the Kashagan field. All instruments are located approximately 100m below the surface. Mark Volanthen, Managing Director of Guralp’s Oil & Gas division stated, “I am delighted that NCPOC has selected Guralp equipment for Kashagan’s life of field monitoring system. Our broadband passive instrumentation delivers information that cannot be obtained using standard seismic equipment. Guralp’s oil & gas division continues to grow rapidly, fuelled by a demand for increased seismic monitoring for risk mitigation, production optimisation, exploration and legislative compliance.” The Guralp system operates continuously and detects passive seismic waveforms including both microseismic events generated in the field and more distant regional seismic events. Data from the instruments will be transmitted in real time to an operations centre. The Guralp system will be installed in the coming months. For more...

EAM now Automatically Saves its Configuration Settings

March 13  Many customers have asked for it, and our firmware team has now implemented it: Uploaded with the latest firmware (starting with Platinum build 12457) our Enhanced Acquisition Module, the EAM, is now capable of automatically backing up and storing its configuration. Every hour, the system scans itself for configuration changes, and if any are found, a new backup is created. Up to 50 automatic backups are kept by the system. As a user, you can also manually create a backup of your current configuration settings. This creates a history of changes to the EAM settings, which can be queried at any time. The response to such a query also includes a listing of the differences in settings between the various configurations. This archive can be called up using the web interface (see screenshot). Why is this feature important? As you set-up your EAM, you may want to try out several different configurations before you decide which settings are best. Instead of manually reprogramming everything, you can now just call up the archive and click on the configuration you want. Another reason is that sometimes changes to the configuration settings happen by accident. Instead of going through your field notes and trying to reconstruct the correct settings, you can now query the history and simply upload the previous configuration. The configuration archive can also be downloaded for storage at a central location. This will save a lot of time when many EAMs need to be programmed using exactly the settings. Also, if you need to exchange an EAM, simply download the current configuration setting from your repository and transfer it to the replacement equipment. An easy to use web interface allows you to store and retrieve various EAM configurations. To access this feature from EAM’s main menu go to “Configuration” and “Save/Restore”. For details on how to upgrade the firmware for your EAM and how to use this new “Save/Restore” feature, see the release notes.   For more information, contact  us at...

New borehole installations in Taiwan and Korea

New borehole installations in Taiwan and Korea January 21 With the recent installation of more than twenty borehole seismometers in Taiwan and Korea, Guralp Systems is continuing its role as the world leader in manufacturing and deploying seismic broadband instrumentation for both shallow and deep boreholes.  In early December two installation teams from our headquarters in the UK spent almost two weeks in Taiwan to deploy a total of ten instruments in boreholes with depths ranging from 200 to 400 meters.  These instruments consisted of six sensors each, a three component CMG-3TB broadband seismometer and a CMG-5TB tri-axial accelerometer.  All six sensors were combined into one borehole package with typical diameter of 89 millimeters.  The customer, Taiwan’s Central Weather Bureau (CWB), is using these borehole sensors to augment its extensive seismic monitoring network. The Korean Meteorological Administration (KMA) took a similar approach in ordering twelve CMG-3TB borehole seismometers for their existing network, which currently comprises more than 110 surface stations.  The first of these sensors was recently installed on the premises of an elementary school in the town of Okcheon in the central part of Korea in a 95 meter deep borehole (station OKCB). These two projects are part of a growing trend among institutions monitoring seismic activity.  More and more of them are starting to use borehole instruments in their respective networks.  The main reason for going below ground is that unwanted seismic noise decreases with depth.  Hence, adding borehole sensors to a network will usually increase its detection level.  Such a gain can be especially pronounced in densely populated countries like Korea and Taiwan. Both recent installations would not have been possible without the close cooperation with GSL’s partners and distributors, San Lien in Taiwan and Heesong Geotek in Korea.  Our partners not only negotiated the respective contracts with our customers, but they were also essential in organizing the drilling of the boreholes, building the necessary infrastructure and providing the all important logistical support during the installation procedure. Two very different installations Since its founding in 1985, Guralp Systems has been developing, building and deploying sensors and digitizers for installations in boreholes on land as well as on the seabed (Ocean Bottom Borehole Systems).  Our product families range from pure analogue sensors to systems combined with down-hole digitizers.  We also offer data transfer to the...
