Seismic/geophysical data is acquired and used for oil and gas (O&G) exploration, reservoirmonitoring, academic research and seismic event monitoring. Although the mechanics of thesystems used are similar, the way data is processed & formatted has evolved independently.‘Life of Field’ (LoF) systems are semi-permanent seismic receiver arrays used to acquirefrequent 3D surveys over a reservoir. Such data are key to providing public accountability(e.g. BP’s Macondo, fracking), understanding more about reservoirs for more efficienthydrocarbon depletion and alerting operators of any unusual events (e.g. seismic activity).Similar requirements apply to industrial microseismic monitoring (i.e. passive observation anduse of small-scale seismic activity).Hence a need to merge these technologies and Data Sets for multi-purpose use has appearedand currently a statutory requirement in many countries (including the UK) exists for the datato be deposited into a national archive in a standard format developed by the Society ofExploration Geophysicists (SEG) for data exchange.However, ways of storing the data acquired (circa 1.5TB/day/reservoir), extracting/reportinginformation in the correct SEG format in near real time, managing the data to suit processingneeds and keeping the data transportable have not yet been fully developed. Also, seismic datais complex and prone to errors/data loss during its lifecycle, making currently available largedata streaming solutions difficult to use.To address these issues, Troika aims to develop a modular solution that automaticallyevaluates seismic events, organises these large volumes of data into discrete records,reformats the data, allowing for conventional seismic data processing and data storage intransportable magnetic tape or any other future media whilst ensuring constant quality control.Post R&D, Troika expects £3.5M increased revenue in the next 5 years, which would increaseexponentially due to growing demand.
