Going with the grains

Drilling and completions practices have driven demand for frac sand to new highs and threaten shortages in some prime shale regions. But what qualities make a sand suitable for fracking, and where is the industry looking for solutions to supply chain challenges.

Digital sentry

More than 100 people may enter and exit a location during unconventional well completions. Information about personnel movement in the field may be as critical to outcomes as the data collected by surface and downhole sensors. Upstream Technology looks at a Houston company’s efforts to capture that missing element in operators’ big data.

FLNG reaches first major mileposts

After many years of tentative build-up, FLNG has just reached its biggest landmark yet. The world’s first such vessel has started up off Malaysia. We look at how the sector has been shaping up, not least through the difficult economic weather of recent times.

Seabed compression in a smaller package

Less than 18 months after pioneering subsea gas compression technology debuted at Statoil’s Aasgard field, the system’s engineers are ready to roll out a second-generation version that provides the same capacity and functionality in a much smaller package.

Depth charge

As the subsea industry moves toward more all-electric systems and components, electric ROVs are gaining ground on their hydraulic counterparts.

Inspection before connection

Subsea tie-backs to host platforms are an attractive option in the current offshore cost-cutting mode. A new remotely deployed inspection tool for J-tubes and risers helps ensure that existing infrastructure is up to the task.

Crossover appeal

Diversification is helping JDR weather a troubled offshore oil and gas market — and could leave the UK umbilical and cable specialist well positioned for a sector turnaround.

In their depths

The diving sector relies on the continual development of new technology, from the equipment used by divers themselves to the vessel that provides support.

Diving sector defies doomsayers

It would be easy to think that diving operations would have become somewhat superfluous, even redundant, in the deep-water era in offshore production. Not so, but an ageing workforce and industry slump present challenges.

Intervention invention

A new modular subsea well access system makes it possible to carry out work ranging from subsea tree installations to permanent plugging and abandonment operations without the expense of a rig.
