The high costs surrounding deepwater developments and the low price of oil are a challenging combination for operators and service companies today.
Considering transportation, services, qualifications, permitting, and infrastructure costs, capital-expenditure costs for deepwater developments are much higher than they are for onshore developments. Similarly, operating in remote locations, where risk must be low and safety and preparedness must be high, operating-expenditure costs are also much higher for deepwater projects than they are for those onshore.
Industry has recognized that, even at USD 100/bbl, the costs of some deepwater developments were not sustainable, and, when it comes to USD 30/bbl oil, it is obvious that the operator cannot justify this capital and operating cost.
During the first decade of the 2000s, escalating oil and gas prices were the rising tide that lifted all boats. It essentially bailed out many floundering projects, masked poor project performance, and bred profligacy and complacency.
In addition, operators were able to justify designing operations that were more flexible and could respond to a greater number of scenarios. However, this resulted in complex designs, which involved more engineering and greater costs.
However, in the current cost environment, the operator must now work with the service companies to discuss what acceptable specifications are. If deepwater operations are to survive going forward, the luxury of unnecessary customization of facilities and individual company specifications of components must cease; industry needs to develop a more-cost-effective “good enough” mind set.
By simplifying, standardizing, and industrializing deepwater technologies, 25–30% reductions in lead time and costs are possible, but there are limits to how much this can save.
The resources we are developing no longer come from massive fields, which limits the economic and cost-saving potentials. Second, the industry cannot create a commodity industry like the automotive industry.
These issues may be overcome with the willingness of the deepwater industry to continue investing in technology developments, and, in particular, technology and constant innovation are what will bring us acceptable economic profitability, which will allow us to continue deepwater development.
