Seismic Survey
optimise their field development and well planning processes.
Te solution comes with a user-friendly
interface and dynamic capabilities that together help to create quick models and move projects forward. Extensive quality controls ensure a greater level of accuracy in both conventional and unconventional geological settings. Integration with CGG’s PowerLog solution offers well analysis for even more insight. Petrophysicists and geologists can compute multiple curves and run a variety of modelling scenarios to better understand their reservoirs. Asset teams and service companies can also use EarthModel Builder to supplement and leverage their current modelling solutions for which they may hold a limited number of licenses. After quality checking and building quick models to assess the information, companies can move the models into their existing technology for reservoir characterisation. Sophie Zurquiyah, senior executive vice
President of CGG’s geology, geophysics & reservoir division, said: “With EarthModel Builder, all E&P stakeholders are now able to build the most up-to-date rock property models. Tis new software offers clients an affordable, exciting and dynamic solution for building and updating models across the life of the field.” In other CGG news, the company has signed an exclusive agreement with Baker
Hughes for RoqSCAN technology. Tis is a real-time, fully portable, quantitative and automated rock properties and mineralogical analyser. Developed by Robertson, a CGG
company, and Carl Zeiss Microscopy, RoqSCAN delivers highly quantitative compositional and textural mineralogical data from drilling cuttings or core pieces, revealing the mineralogical DNA of the reservoir. Tis service can be provided at the wellsite during drilling operations, or later in core stores, field offices and laboratories. Baker Hughes will include RoqSCAN in its shale reservoir evaluation services as part of the Shale Science Alliance with CGG. Te agreement further strengthens the strategic relationship between the two companies, which is designed to help operators better understand shale plays and predict ‘sweet spots’ based on the combination of seismic attributes and accurate wellbore measurements. “RoqSCAN acts as an innovative bridge, delivering important geologic information to our integrated geoscience offering with Baker Hughes and providing a ground truth for our predictive reservoir models. It allows us to properly characterise the geological factors behind sweet spots and optimise the completion design and fracturing to maximise production and reduce costs in these shale play operations,” explained Zurquiyah. l
The RT System 2 is comprised of the following components: wireless remote units (WRU); wireless infrastructure to transmit seismic data from the distributed modules to the central repository; a backhaul system to ensure secure data transportation; a central data management, display, storage and control system.
The RT System 2 scales to tens of thousands of channels.
Seismic contractors no longer need to sacrifice real-time data return and risk compromising the quality and the security of their data to get access to a high channel-count, cable-less system.
RT System 2 takes advantage of highly-efficient radio technologies, instead of bulky, heavy, unreliable cables and by overcoming the data QC, collection, transcription, and security limitations of ‘blind’ nodal systems.
TGS expands electromagnetic data coverage in the Barents Sea T
GS and Electromagnetic Geoservices have agreed to further expand the companies’ previous cooperation
agreement in the Barents Sea. TGS will partner with EMGS to acquire electromagnetic (EM) data over four additional blocks in the Hoop area of the Barents Sea to bring its total joint ownership of multi-client EM data in this area to 21 blocks. In addition the companies will jointly invest in EM data acquisition over 14 new blocks in the south- eastern Barents Sea.
Te new 3D EM data will be acquired by the M/V
Atlantic Guardian. Data will be available to clients through both EMGS and TGS. “TGS and EMGS are pleased to expand their cooperation
in the Barents Sea,” commented Stein Ove Isaksen, senior vice president Eastern Hemisphere for TGS. “We believe that high quality, integrated EM and seismic data will be
very valuable for oil companies participating in the 23rd Norwegian licensing round.” TGS has also announced the expansion of multi-client
2D surveys offshore Eastern Canada with plans to acquire more than 30,000km of seismic data, in partnership with PGS, utilising two vessels during the 2014 acquisition season. TGS says this project will provide valuable data covering expected areas of interest to be released by Canada’s Newfoundland and Labrador Offshore Petroleum Board as part of the new land tenure system announced to the industry on 19 December 2013. Tis new data will also complement TGS’ existing 47,600km of 2D data acquired during the 2011, 2012 and 2013 acquisition seasons in this region. Data processing will be performed by TGS and final data will be available to clients Q3 2015. l
