Deepwater Fields

Deepwater capital expenditure has nosedived since the oil-price crash of 2014 and has not quite recovered because of the high level of break-even prices required, but some oil companies maintained their interest in the sector and went ahead with big-ticket projects anyway. Most believe the sector has bottomed out.

Brazil’s presalt region is among the areas driving deepwater oil and gas development, while others struggle with costs and technical complexity. So, in a low-oil-price environment, are such deepwater projects viable?

The major players in the deepwater market have made significant efforts to minimize costs and increase efficiency, thus shaping 2019 capital budgets.

That means activity levels in 2019 likely will mimic those of 2017–18, with perhaps some small gains from small operators taking advantages and looking for opportunities in the current low-cost environment.

However, the situation is darkened by global market pessimism. Adding to this, operator project-execution decisions have been delayed and lack of commitment and direction has caused operators to delay deepwater projects and leave the pipeline of future work empty.

Even if operators do make decisions in late 2019 to go forward with these projects, the projects are unlikely to commence until late 2020 or even 2021.

Royal Dutch Shell is considering only the Gulf of Mexico in their strategic deepwater development going forward to 2020 and beyond, and, despite low oil prices, Shell is advancing its Kaikias, Appomattox, and Coulomb Phase 2 projects in the deepwater Gulf of Mexico, reducing break-even costs and cycle times.

Through the forecast period, Africa and the Americas will continue to lead the deepwater market, accounting for 79% of forecast expenditure.

Floating production, storage, and offloading vessels will continue to dominate the floating production and storage (FPS) market, with a total of 33 deepwater units (out of 41 FPS units in total) expected to be installed during the 2018–22 period, representing 78% of FPS expenditure.
