Offshore/subsea systems
Updates about global exploration and production activities and developments.
Once labeled “undrillable,” Brazil’s heavy-oil Atlanta field in the Santos Basin faced technical, financial, and logistical challenges. But through a phased approach, clever reuse of assets, and disciplined project execution, Brava Energia transformed a risky deepwater asset into a producing field with 172 million BOE in 2P reserves.
This paper describes the use of coiled tubing in a pilot project for carbon dioxide injection, enabling evaluation of the conversion of an existing oil field for CCS purposes and derisking storage-development uncertainties before having to cease hydrocarbon production.

Trials of the robotics company’s Hydronaut and Aquanaut system are expected in the third quarter of 2022 after the companies conducted a successful feasibility study.
-
Many hurdles for marinization of green hydrogen production already have been overcome in the offshore oil and wind sectors. A fresh set of challenges, however, will rise around developing and deploying hydrogen production facilities offshore.
-
The paper provides an approach to mitigating the adverse effects of mercury found in production fields, including treatment-facility requirements and suitable technologies for production fields and onshore facilities.
-
The paper describes a systems-engineering-guidance document currently being developed, and outlines the benefits associated with the use of formal systems-engineering processes when designing complex facilities.
-
The partnership of Subsea 7 and Flasc has a plan to use out-of-service pipelines as pressure vessels in a hydro-pneumatic energy storage concept.
-
The paper describes the components of an all-electric system, how it fits within a subsea application, and how it compares with traditional electrohydraulic systems.
-
The authors describe a joint industry project focused on collaboration and knowledge-sharing to improve the competitiveness of Australia’s oil and gas industry by addressing critical challenges associated with subsea-equipment failure.
