Onshore/Offshore Facilities
This paper identifies opportunities and risks associated with repurposing an offshore oil and gas platform for green hydrogen production. Various technical scenarios were investigated for the case study platform, and their profitability was determined using economic calculations. In addition, all the submodels were compared with standard decommissioning costs for reco…
This paper documents the testing, integration, and field deployment of a metal expandable packer used as an openhole toe isolation plug in a deepwater well under high-pressure, high-temperature conditions.
This paper presents an approach for safe, efficient, and cost-effective legacy well reabandonment.

The fully remote inspection was conducted with an ROV to increase worker safety and security and reduce environmental exposure on an offshore platform. -
IOGP JIP33 plans to publish more than 30 specifications by the end of the year.
-
The paper describes options for hydrate and integrity management and the required modifications to both subsea and topside facilities to enable an operational philosophy change.

In 2015, the world’s first subsea multiphase gas compression system was installed offshore Norway. The system comprises two-off 5-MW machines configurable for serial or parallel compression. This system has now gained considerable and valuable operational experience.
-
Both operational experience and studies of future offshore gas-field developments are showing that subsea gas-compression systems not only reduce investment costs but also increase recovery significantly.

While it remains today only an idea, there are but a few barriers keeping an unmanned floater from being realized, according to one of the world’s leading offshore engineering firms.

Often it is too difficult to create the fault conditions necessary for training a predictive maintenance algorithm on the actual machine. A digital twin generates simulated failure data, which can then be used to design a fault-detection algorithm.
-
A multizone water-injection project has ultimately proved a method of using intelligent completion interval-control valves in place of traditional sand-control completions in soft sand reservoirs.

Repair work on the Gorgon LNG plant’s propane heat exchangers is underway. Planned maintenance on the Gorgon Train 2 was expected to end in July.
