Tesla Exploration Inc. was awarded a 3D/3C project to explore 90 sq. miles of the High Plains near Cheyenne, Wyoming. Known as Bear CreekSCAN, the project location encompassed open prairies, rolling hills and scattered, cultivated fields. Unpaved and two-track dirt roads provided reasonable access to the survey area, making deployment and shooting easier for Tesla crews in this terrain. Because of the size of this largescale cableless acquisition project, Tesla needed a system that could withstand rigorous field usage, provide optimal operational flexibility and offer wireless QC capabilities for increased crew productivity.
Tesla Exploration Ltd. was selected for the Willesden Green 3D/3C seismic acquisition project, a winter deployment covering 260 sq km (100 sq mi) near Rocky Mountain House in Alberta, Canada. The project area encompassed a working oil field production area and unpopulated terrain with rolling hills and patches of dense evergreen forest. Unpaved roads offered reasonable access, but Tesla crews also required snowmobiles in off-road areas for greater efficiency in deployment and acquisition QC.
Geophysical service providers rely heavily on equipment manufacturers such as INOVA for integrated solutions that can support the smallest 2D projects to the largest most complex 3D high productivity Vibroseis (HPVS) operations. BGP, a subsidiary of China National Petroleum Company and the world's largest land seismic contractor, continually seeks cutting-edge seismic technology to maintain their competitive edge for providing high quality data acquisition services. BGP's numerous seismic crews operate across the globe in all types of challenging terrains and extreme weather conditions, and require a stable, easy-to-use recording system that can perform in the toughest seismic programs.
Challenges across the industry are forcing operators to find innovative approaches and evaluate their acquisition technologies more closely. In order to compete in the land seismic industry, geophysical providers require equipment capable of overcoming a diverse range of operational demands and environmental obstacles. Surface infrastructure and obstructions add a myriad of challenges for crews who must achieve high levels of productivity while producing the data integrity their customers demand.
In many regions of the world, the majority of geophysical service providers continue to use cable-based acquisition technologies for conducting the simplest 2D to the largest, most complex 3D surveys. Crews have equipped themselves with the most advanced cable-based systems on the market to take advantage of their unmatched reliability and accuracy in providing real-time data acquisition. As the seismic industry demands higher quality data at lower operational costs, acquiring high-density sampling with High Productivity Vibroseis (HPVS) is becoming more favorable. However, these projects introduce extreme challenges in managing equipment, personnel, logistics, and achieving desired productivity levels.
G3i Overcomes Siberia's Harshest Subzero Temperatures Unscathed – The GeoGlobAll Group, a leading oilfield service provider in Russia, has been exploring the Russian republic of Yakutia for many decades. In 2012, OJSC YakutskGeofizika (YGF), a wholly owned subsidiary of GeoGlobAll, was awarded a contract to perform several 2D seismic surveys near the Arctic Circle. They needed a new acquisition system that was highly reliable, easily deployable and consumes minimal power to reduce battery changeouts. In Yakutia, temperatures below -50°C (-58°F) are common during the winter months, which makes the need for rugged and weatherized acquisition equipment essential. With temperatures this extreme, minimizing the time the crew was exposed to the elements was a priority during the seismic operatio
In December 2007, Global Geophysical Services, a geophysical service provider operating twelve land survey crews worldwide, began a five-month, 3D data acquisition in Oman. The acquisition specified an advanced vibroseis recording methodology covering approximately 2,793 sq km of relatively flat desert terrain for characterization of a target approximately 6,000 meters below the surface. With aggressive daily productivity parameters and simultaneously recorded offset separated shot points required by the E&P operator, Global sought a highly reliable vibroseis vehicle with faster acceleration that would provide greater energy input while minimizing the logistical quandary of mobilizing and coordinating multiple vibs per fleet.
