Sercel Delivers 508XT Acquisition Systems
Sercel has announced the successful delivery of five of its state-of-the-art 508XT seismic acquisition systems to India’s national oil company, ONGC.ONGC selected Sercel’s cross-technology (X-Tech) solution to conduct various 3D surveys for a total of 40,000 channels across India in challenging environments, from jungle to steppe plain and even desert.The specific challenges faced across these terrains make the 508XT system a natural choice. Sercel’s renowned robust build quality ensures minimal downtime even when operating in the harshest conditions.
Sercel Launches DAS Seismic Solution
Seismic equipment and reservoir monitoring instrument manufacturer Sercel has launched its first distributed acoustic sensing (DAS) seismic solution.SigmaWave, designed in partnership with DAS specialist Fotech Solutions, integrates Fotech’s fiber optic monitoring technology into Sercel’s seismic acquisition systems. The result, Sercel says, is the first integrated distributed acoustic solution designed exclusively for borehole seismic applications.DAS are a photonic sensing technology that convert an optical-fiber into a linear array of discrete vibration sensors.
Sercel Extends Capability of 508XT Seismic Acquisition System
CGG announced that Sercel has launched a transition zone version of its state-of-the-art 508XT seismic acquisition system. Seismic crews will now be able to deploy the 508XT solution in marsh zones and water depths of up to 25 m.Designed with reinforced hardware to withstand the complex challenges of operating in shallow water environments, the new 508XT transition zone system also benefits from Sercel’s unique fault-tolerant X-Tech cross-technology architecture, featuring local storage and automatic rerouting to maximize survey productivity.
CGG Completes Perdido Subsalt Survey for Pemex
CGG has completed ahead of schedule an 11,500 sq km wide-azimuth (WAZ) survey on behalf of Pemex in the deepwater Perdido area. This new survey has been acquired perpendicularly to existing WAZ data and the combined Imaging of this first large-scale orthogonal WAZ data set is expected to provide significantly enhanced subsalt imaging results. A fast-track TTI RTM image for the first block of approximately 5,200 sq. km was delivered earlier than planned, helping to guide the client’s drilling operations. This landmark survey…
CGG Launches Shallow Reservoir Imaging Solution
CGG announced at ONS 2016 the launch of TopSeis, the latest evolution in offshore broadband seismic, specifically designed to overcome the intrinsic lack of near offsets inherent in 3D towed-streamer seismic. Exacerbated by the use of progressively wider spreads to meet the industry’s quest for greater efficiency, the lack of near offsets leads to an inability to image shallow geological features, such as faults, gas pockets, channels and stratigraphic pinch-outs, effectively. By overcoming this shortcoming, TopSeis enables…
Offshore Oil & Gas: Brazil’s Northern Frontier
In an effort to spread out oil and gas production to other parts of the country and increase overall oil production, Brazil has finally intensified hydrocarbon exploration along its northeastern and northern coasts. These are some of the poorest regions in the country and infrastructure for oil and gas exploration is minimal, yet significant discoveries and seismic indicators of large reservoirs are tantalizing and have attracted major local and foreign investors. Potential for oil discoveries in the area is proven, yet players will be faced by many challenges offshore and on land in order to uncork reservoirs at the Northern Frontier.
