Improvements for positioning subsea vehicles

iSURVEY will be using SPRINT to support a wide variety of multi-beam seabed surveys using deep-rated ROVs

Drive upgrade enhances thruster performance on seismic survey vessels

Upgrade improves the effectiveness and local ability of the ship board maintenance teams

Navigation system uses ring laser technology to provide reliable data

The latest addition to the TSS (International) range is its Orion Inertial Navigation System which uses ring laser technology and the latest TSS algorithms to provide highly accurate, reliable data in a compact and affordable package.

Mid-span cable attachment provides superior holding strength and bend

Towing multiple seismic arrays in the search for oil requires a reliable, high-strength, mid-span attachment point for paravanes and floats.

Portable transducers for marine surveys

The M162, from Airmar Transducers, is a dual frequency portable transducer used for marine survey applications.

Data processing and presentation

Clydeside Surveys’ processing suite has been designed to be portable and can be loaded both onto laptop PCs for field use, as well as larger PCs for final data presentation in the office.

Survey sounder model provides quality chart and digital depth information

The Innerspace Technology Model 456 Dual Frequency Hydrographic Survey Sounder provides survey quality electronic chart and digital depth information.

Mix and match profiling products

Applied Acoustics manufactures a variety of sub-bottom profiling products based on a component system configuration, so that the optimum package can be tailored for any particular application.

Oil prices hit US$100 a Barrel for the first time

In the first trading day of 2008, NYMEX crude oil futures traded at US$100/b for the first time ever, powered by renewed violence in Nigeria, supply concerns, and ongoing tension in the Middle East,

Interpreting seismic data may be a science, but it is also an art

Acquiring the seismic data is essentially taking acoustic pictures through the earth’s strata ­– rather like a camera that, for all the effort to create a precision machine capable of generating pin-sharp images, always delivers blurred results that then need correcting.

Hydrocarbon recovery: future is sea floor

Since the uptake of marine seismic methods by the oil industry in the mid-1960s ocean bottom seismic data acquisition has remained a minority

Climate change now adds an urgency to collecting oceanic data

Hydrographic survey is one of those disciplines that gives the impression of having been around forever. Wind the clock back to the days of William Bligh, Captain Cook and Fitzroy and the survey work carried out by the UK’s Royal Navy was headline-grabbing stuff, likewise early expeditions carried out around Antarctica and in waters to the north of Canada.

Time-lapse seismic now integral part of reservoir management

A measure of how important Time-lapse (or 4D) seismic has become is that in the order of 75 per cent of current seismic survey work on the North-west Europe Continental Shelf relates to 4D assessment

Navigation system which uses ring laser technology

ROVs enter the seismic market

Electric ROVs have seen a major shift in both size and work capability

Mid-span cable attachment provides superior holding strength and bend protection

Towing multiple seismic arrays in the search for oil requires a reliable, high-strength, mid-span attachment point for paravanes and floats

Internal and external inspection of submerged pipelines

Pipelines are used throughout the world to transport various substances, such as natural gas and oil, over long distances. While pipelines run both over land and sea, Thomas Petersson will focus on submerged pipelines.

The future is on the sea floor

Dr Chris Walker argues that the oil industry is about to witness a paradigm shift in the utilisation of both re-deployable and permanently installed ocean bottom data.

Panama canal expansion

Ron Kaufmann reports on geophysical investigation along critical portions of the expansion route for the Panama Canal
