“We recognise the significance of this opportunity with Shell and look forward to the execution of this project work.”

The global offshore well intervention market is set for a period of extended growth in light of stable oil prices forecast in the short-term, maintained oil demand in the medium- and possibly long-term, and ever-increasing environmental pressures.

Globally, spending on well intervention is on the rise with Rystad Energy predicting an increase by almost 20% in 2023 to take the total tally to US$58bn. This is just the start of a forthcoming surge with 17% of wells predicted to go through the intervention process by 2027.

North America accounts for 64% of the total wells ready for intervention by 2027, according to Rystad, giving rise to the dramatic potential of the market in the Gulf of Mexico. According to BSEE, there are approximately 1,885 active production platforms on the OCS with more than 60% older than 25 years.

This is leaving operators grappling with the need to maintain production rates while also dealing with ever-ageing infrastructure, with mounting regulatory pressure increasing the need to address decommissioning obligations. In facing this conundrum, an increasing amount of well intervention activity is highlighting the importance of this service as a means to address both sides.

As new technological innovations become more viable and the understanding around methods such as light well intervention build, the market will only advance in stature, suggesting it will finally meet the potential it has promised for so long, creating a tantalising future for the crowd of service and equipment providers offering their assistance.

Fervo Energy, one of the leaders in next-generation geothermal technology, has announced the successful completion of its well test at its full-scale commercial pilot project, Project Red, in Nevada.

The successful test confirmed the commercial viability of Fervo’s drilling technology and further established Project Red as one of the most productive enhanced geothermal systems (ESG) to date. The 30-day well test achieved a flow rate of 63 litres per second at high temperature, which enabled 3.5MW of electric production, setting new records for both flow and power output from an EGS.

Fervo is the first company to successfully drill a horizontal well pair for commercial geothermal production, achieving lateral lengths of 3,250 ft, and reaching temperatures of 191°C. Data collected through the course of this pilot prohject will enable rapid advancement in geothermal deployment, with Fervo’s next horizontal well pair planned to achieve more than double the power output of the pilot design.

Tim Latimer, Fervo Energy CEO and Co-Founder, said, “By applying drilling technology from the oil and gas industry, we have proven that we can produce 24/7 carbon-free energy resources in new geographies across the world. The incredible results we share today are the product of many years of dedicated work and commitment from Fervo employees and industry partners, especially Google.”

Fervo and Google signed the world’s first corporate agreement in 2021 to develop next-generation geothermal power. The end goal for the partnership is to power Google’s Cloud region in Las Vegas with an ‘always-on’, carbon-free resource that will reduce the company’s hourly reliance on fossil fuels.

Results from Project Red indicate that geothermal energy could supply more than 20% of US power needs and compliment wind and solar in order to reach a fully decarbonised grid.  

Trendsetter Engineering, a provider of specialised subsea hardware and offshore service solutions from exploration drilling through to abandonment, has announced the recent completion of two deepwater well stimulation campaigns for major operators in the Gulf of Mexico.
