During the production phase of a reservoir, natural phenomenon, such as movement of fluids, changes in pressure and stress in and around reservoirs occur. In high-pressure reservoirs, pressure depletion during production is associated with compaction within the reservoir causing stretching or extensional stresses in the overburden and underlying formation. This causes variation in velocities and formation thickness, which can be observed as 4D time shifts between successive vintages. Tracking the movements of fluids due to production, for example, gives valuable information about the depletion of a field, and can indicate areas of bypassed oil or gas.

OTC Brasil 2013 – Tech Highlights: Marlin AUV

January 6, 2014

The Technical Program at the OTC Brasil 2013 was definitely one of the event’s major attractions. There we’re dozens of presentations and panels during each of the 3 days, and it was definitely hard to pick which to attend. I personally went to about 12 of these and not one disappointed me. I have to start somewhere, so I actually chose a presentation from the last day to begin this series. At this point I believe that just about everyone knows what an AUV is, but in case you don’t, it is the acronym for Autonomous Underwater Vehicle. These come in all sorts of shapes and sizes, having various capabilities and possible uses. I must admit that I was impressed with the Lockheed Martin Marlin® AUV. At first glance it resembles what you’d expect from any top of the line AUV.

Subsea Connection Systems - FMC's UCON System

Subsea oil fields are dependent on a large amount of connections between various kinds of subsea equipment in order to function. They allow umbilicals, flowlines, risers and rigid jumpers to connect to manifolds, x-mas trees, BOPs, pipelines and riser bases. These connections need to be absolutely safe and reliable as connection problems can cause a series of problems in operating subsea equipment which may affect exploration and production only a little or cause these to partially or completely stop. On top of that subsea connection failures may also cause oil spills or gas leakage in the environment in small or large amounts, driving operators and subsea service and equipment providers to invest heavily in research regarding ideal connection manufacture…
