EM Survey North of Shetlands
PetroMarker AS, a marine EM specialist oil and gas exploration service company based in Stavanger, Norway, has been awarded a contract for an EM survey in the frontier West of Shetland area by Faroe Petroleum (UK) Ltd. Following a competitive invitation to tender, PetroMarker has been selected to carry out the survey on the Grouse prospect, which is located in UK License P1853, about 200 km north of the Shetland Islands, a promising area for future developments. Grouse is a large structural and stratigraphic post-basalt prospect of Upper Eocene age, on the southern flank of the Pilot Whale Anticline, part of a new exciting exploration play in this remote area. The survey will be executed with the newly mobilized ‘Normand Baltic’.
PetroMarker’s EM technology is based on the unique, fully-patented, vertical electric method, TEMP-VEL, which offers better accuracy, high sensitivity and deeper penetration, depending on local geology. The company’s activities range from feasibility studies prior to offshore investigation, preparation of the offshore surveys in terms of survey configuration and planning, acquisition and processing of the data, to finally interpretation and recommendation to oil companies.
Challenges and Opportunities
Challenges for today, opportunities for tomorrow: the tantalizing theme for the second Arctic Technology Conference (ATC) due to be held in Houston, Texas, on December 3–5 this year. This highly focused international conference addresses the cutting-edge technologies and innovative practices needed for exploration and production in the Arctic. Part of the Offshore Technology Conference portfolio of events and managed by the AAPG, ATC brings together a dozen professional societies and associations to create a comprehensive technical program which features hundreds of technical presentations and posters. There are also a number of topical panel discussions covering subjects ranging from Arctic production to oil spill preparedness and specialist technology. And new for 2012: the Spotlight on Arctic Technology awards, with exhibitors competing for top honors.
The inaugural event last year attracted 1,300 attendees from 23 countries and was deemed a great success and this year’s conference is expected to be even bigger. From pipelines to flow assurance, environmental regulations to vessels – you will see it or hear it at ATC.
Onshore Canning Basin Reprocessing
Searcher Seismic Pty Ltd has recently commenced a major onshore multi-client reprocessing project in the Canning Basin, Australia, which will tie-in over 60 wells and deliver approximately 40,000 km of high-quality reprocessed seismic data. The magnitude of the Onshore Canning Super-Tie™ Reprocessing Project means that a multi-phased approach has been implemented, and phase 1 has now commenced, with priority lines expected to be delivered to participating companies in Q4 2012.
The Onshore Canning Basin has been generating increasing levels of interest recently due to a combination of conventional exploration success and recognition of huge unconventional resource potential in the basin. Recent bid rounds and acreage uptake reflect this trend and have been highly contested with increasingly aggressive work program commitments required to secure acreage.
Searcher, which designs, manages and markets 2D and 3D non-exclusive seismic, is uniquely placed to tackle such a large project, having recently completed reprocessing over 80,000 km of similar data offshore Australia.
1,000 Fugro Surveying Courses
At the end of June 2012, the Fugro Academy delivered its 1,000th surveying course. The Academy is an internal organization which was created to support corporate and divisional initiatives relating to training of Fugro staff at all levels. Courses range from induction modules to technical and professional training and management development, and in addition to surveying they cover everything from health and safety and office software applications to leadership and interpersonal skills. Courses are delivered by either Fugro trainers or external providers and can be traditional instructor-led training, online e-learning or virtual classroom sessions.
Fugro Academy, created in 2006, has been delivering survey training since then and the 1,000 survey courses were undertaken by over 7,600 staff, representing about 35,000 days of training. Survey courses are developed to support the training and development of Fugro’s surveyors, engineers, geophysicists and data processors. Training starts with basic induction to and familiarization with the company and offshore survey operations, leading to technical courses in systems and processes used by Fugro, plus supervisory and management training for senior staff as they take on relevant positions in offshore operations. Almost 50 different courses are available to Fugro staff to help them develop the experience and competence required to perform their roles. A dedicated team of experienced survey professionals with many years of experience design, develop and deliver these courses.
Third European Shale Gas Conference
European shale gas exploration could be said to still be in its infancy, but interest in the resource continues to increase and to date, shale gas exploration is underway in Poland, Sweden, Austria, the UK and Germany, among other countries.
Poland is considered Europe’s hot spot, although some estimates suggest that shale resources in France may be as big as Poland’s – if they choose to develop them. Romania is also considered to hold significant potential. It is appropriate therefore that Warsaw in Poland is due to host the 3rd annual Shale Gas World Europe conference at the end of November, 2012. Over 80 speakers from across Europe and beyond will be presenting their ideas, covering a range of related but diverse issues, such as regulatory frameworks, drilling technology, water management and geophysical advances.
Improving Reservoir Evaluation
To more accurately pinpoint the extent and location of hydrocarbons in a reservoir, operators have relied on pulsed-neutron measurements for more than 40 years. The industry’s increasing interest in gas production from both conventional and unconventional reservoirs over the past decade has prompted the need for such tools to provide a heightened level of sensitivity and accuracy to formation evaluation behind casing.
Weatherford’s pulsed-neutron, cased-hole evaluation system known as the Raptor™ Pulsed-Neutron Tool was designed specifically to fulfill this need. With the industry’s first five-detector array that incorporates unique lanthanum bromide detectors and a fast-neutron detector, the technology yields a more sensitive measurement of the neutron-gamma transport field in gas-filled formations. These features, combined with the tool’s calibration system, enhance accuracy, spectral processing, signal-to-noise ratios and logging speeds, ultimately providing operators a higher degree of confidence in the data in a shorter period of time.
Interpretation software includes algorithms for determining shale and mineralogy effects in carbon-oxygen and formation gas saturation measurements, which replace operator intuition with quantitative petrophysical processes. In addition, new computer-based characterization techniques can distinguish previously indistinguishable wellbore and reservoir conditions in all-gas formations, in formations and boreholes with varying oil and water properties and in multi-tubing strings.
The new technology has been successfully field-tested in more than 40 wells in the United States, Middle East, Europe and the Caribbean in both unconventional and conventional gas reservoirs.
