The future of offshore: fully subsea?

Offshore developments will change dramatically in the 2020s, eliminating new production platforms in favour of fully subsea solutions. The opportunity can increase a typical project’s NPV by 50%, reduce its breakeven by one-third and effectively eliminate upstream CO2 emissions. We have reviewed 1,850 patents to find the best-placed operators and service providers, versus others that will be disrupted. Overall, the theme supports the ascent of low-carbon natural gas, which should treble in the energy mix by 2050. This 22-page note presents the opportunity.


The offshore oil and gas industry’s progress towards ‘fully subsea’ developments, without any platforms or surface infrastructure being necessary, is reviewed in detail in pages 2-5, covering key projects and milestones from 1985-2000.

30% economic savings in both capex and opex are quantified line-by-line, across c50 cost lines, in pages 6-9.

1.5x NPV uplifts and 4pp IRR uplifts are quantified by modelling a representative fully greenfield gas-condensate project on pages 11-12.

CO2 emissions can be virtually eliminated by a fully subsea development solution. Pages 12-13 add up the impacts of higher efficiency, power from shore, fewer materials and the elimination of PSV/helicopter trips.

The key engineering challenges for fully subsea systems, which remain to be resolved, are summarized on page 14.

Who benefits from the trend toward fully subsea systems, is described from page 15 onwards after reviewing 1,850 patents around the industry. This includes both the leading service companies and operators (primarily Equinor, but also TOTAL, Shell).

The leaders in subsea compression technology are assessed on pages 16-17.

The leaders in subsea power systems are described on pages 18-19.

The leaders in next-generation subsea robotics are assessed on pages 20-21.

Others are disrupted, as is described in detail in page 22.

Covered service companies in the report include ABB, Aker, Eelume, GE, Kraken, Oceaneering, OneSubsea, Saipem, Siemens, Technip-FMC, Wood Group, the PSV and helicopter sector, and c20 early stage companies in next-generating subsea robotics.

Guyana: carbon credentials & capital costs?

Prioritising low carbon barrels will matter increasingly to investors, as they can reduce total oil industry CO2 by 25%. Hence, these barrels should attract lower WACCs, whereas fears over the energy transition are elevating hurdle rates elsewhere and denting valuations. In Guyana’s case, the upshot could add $8-15bn of NAV, with a total CO2 intensity that could be c50% below the industry average.


Pages 2-3 introduce our framework for decarbonisation of the global energy system. Within oil, this requires prioritising lower carbon over higher carbon oil barrels.

Pages 3-6 outline the economic value in Guyana, which is now at the point where it is hard to move the needle with further resource discoveries.

Pages 7-8 show how lower WACCs can be trasnformative to resource value, even more material than increasing oil prices to $100/bbl.

Pages 9-17 outline the top technologies that should minimise Guyana’s CO2 emissions per barrel, including flaring policies, refining quality, midstream proximity, proprietary gas turbine technologies from ExxonMobil’s patents and leading digital technologies around the industry.

Our conclusion is that leading companies must deepen their efforts to minimise CO2 intensities and articulate these initiatives to the market.

Patent Leaders in Energy

Technology leadership is crucial in energy. It drives costs, returns and future resiliency. Hence, we have reviewed 3,000 recent patent filings, across the 25 largest energy companies, in order to quantify our “Top Ten” patent leaders in energy.


This 34-page note ranks the industry’s “Top 10 technology-leaders”: in upstream, offshore, deep-water, shale, LNG, gas-marketing, downstream, chemicals, digital and renewables.

For each topic, we profile the leading company, its edge and the proximity of the competition.

Companies covered by the analysis include Aramco, BP, Chevron, Conoco, Devon, Eni, EOG, Equinor, ExxonMobil, Occidental, Petrobras, Repsol, Shell, Suncor and TOTAL.

Mero Revolutions: countering CO2 in pre-salt Brazil?

The super-giant Mero field in pre-salt Brazil is not like its predecessors. While prolific, it has a 2x higher gas cut, of which c45% is corrosive and environmentally unpalatable CO2. Hence, Petrobras, Shell, TOTAL and two Chinese Majors are pushing the boundaries of deepwater technology. Our new, 16-page note assess four innovation areas, which could unlock $2bn of NPV upside. But the distribution of outcomes remains broad. $4bn is at risk if the CO2-challenges are not overcome.


Page 2 provides background on pre-salt Brazil, especially the flagship Lula project, which a new super-giant, Mero, is trying to emulate.

Page 3-4 contrast Mero to Lula, based on data from flow-tests. Mero has a 2x higher gas-cut and c8x higher CO2.

Page 5 reviews Petrobras’s own internal concerns over CO2-handling at Mero, and how they are expected to sway the decline rates at the field.

Page 6 outlines our valuation of the Mero oilfield, testing different CO2-handling scenarios. Our full model is also available.

Pages 7-8 review Mero’s FPSO design adaptations, to handle the field’s higher gas and CO2. These will be 2-2.5x larger FPSOs than Lula, by tonnage.

Pages 8-10 illustrate pipeline bottlenecks facing pre-salt Brazil. After considering alternative options (re-injection, LNG), we argue more pipelines may be needed.

Pages 10-12 describe riser innovations, which may help handle the risks of CO2-corrosion at Mero. One option is overly complex. The other is more promising.

Pages 12-16 cover the holy grail for Mero’s CO2, which is subsea CO2 separation. This would be a major industry advance, and unlock further billion-barrel resource opportunities. Upcoming hurdles and challenges are assessed.

Pages 15-16, in particular, cover Shell’s industry-leading deepwater technology, which may be helpful in maximising value from the resource, longer-term.

New Risers for pre-salt Brazil?

Petrobras has patented next-generation riser designs, to handle sour-service crude from pre-salt Brazil. This is needed after prior cases of riser-failure, e.g., at Lula. Its new solution could also support development of higher-CO2 fields, such as Libra. But complexity is an order of magnitude higher. A simpler alternative is the growing potential from thermo-plastic composite pipe, which resists corrosion and is 45% more economical than conventional risers.

Can Technology Revive Offshore Oil?

The appetite to invest in new offshore oil projects has been languishing, due to fears over the energy transition, a preference for share-buybacks, and intensifying competition from short-cycle shale. So can technology revive offshore and deep-water? This note outlines our ‘top twenty’ opportunities. They can double deep-water NPVs, add c4-5% to IRRs and improve oil price break-evens by $15-20/bbl.


Pages 9-18 of the note outline each of our ‘top twenty’ focus areas, after reviewing 1,500 patents and 300 technologies across the industry. In each case, we outline which companies are most advanced.

Our work shows it is essential to invest with – or have your resources managed by – technology leaders. The industry must also keep improving, to re-excite investment.
