A vessel-deployed mechanical cutting device reduces the cost of offshore wellhead removal.

Unique snubbing unit cleans out long section of decommissioned pipeline in one trip

Bobby Bray, Charles C. Overstreet

Using an innovative snubbing/hydraulic workover unit, in conjunction with a semisubmersible well intervention vessel, enabled an operator to clean out 5½ miles of decommissioned deepwater GOM pipeline in an environmentally safe and cost-effective manner.

Shared values and integrated technologies optimize well abandonment operations

Glenn (GT) Iversen

A synergistic approach to finishing responsibly goes beyond traditional barrier placement for P&A and helps the operator to achieve the best possible environmental and financial results.

Driving toward safer, environmentally conscious offshore operations: Moving chemical storage to the seabed

Julie Lund

Subsea systems offer flexible offshore storage of oil and condensate. NOV has developed the technology further into a safe, eco-friendly option for the subsea storage and injection of chemicals.

FiGS changing the course of the industry once again

Sissel Richardsen

Innovative technology and new ways of working are changing the way firms think about cathodic protection surveys and optimisation, increasing both the efficiency and efficacy, while reducing the carbon footprint.

Assessing industry performance in America’s great Lower Tertiary play

Chuck White, Roy Shilling, Vamsee Achanta, Jeremy Walker, Terrance Ivers

This first of two articles following up Frontier Deepwater’s February 2020 World Oil article clarifies how and why industry’s efforts to develop the massive Wilcox Lower Tertiary trend in the ultra-deep waters of the Gulf of Mexico with subsea hub-spoke systems and strategies have failed commercially.

Novel flexible pipe overcomes challenges in pre-salt subsea developments

Andre Macedo, Mauricio Brandao

An innovative technological solution has overcome flexible pipe corrosion cracking in high CO2 content fields, including Brazil’s pre-salt offshore developments. The new pipe system is verified to extend service life by at least 50%, compared to standard flexibles.


U.S. operators working down DUC backlog

Craig Fleming

Despite a modest reduction in the DUC inventory, there are still 7,086 wells waiting on completion. With the industry in disarray, it has become increasingly likely that many of these horizontal boreholes may never be completed.

Machine learning for predicting stochastic fluid and mineral volumes in complex unconventional reservoirs

Fred Jenson, Chiranjith Ranganathan, Shi Xiuping, Ted Holden

A machine learning workflow can quickly, and accurately, predict mineralogy, porosity and saturation in multiple wells to better understand productive layers in unconventional oil reservoirs.

How COVID-19 accelerated the cloud adoption future in oil & gas

John Tully

The need to digitally transform — by taking actions such as streamlining and automating business processes, managing data across the organization and overseeing remote workers — is only greater in the face of COVID-19 developments.

For ESG investors, ‘Clean Fracs’ could mitigate environmental impacts

Mason Anderson

As regulatory requirements and ESG reporting and transparency increase to address gas flaring, “clean fracs” could be one solution for upstream oil and gas companies towards an energy transition.

Improving the bottom line in the Permian

Connor Docherty

One way to reduce frac fleet costs in the Permian is to decrease the rate of seat replacements by utilizing new carbide technology.

Keeping offshore environments safe: The power of remote medical teams

David Thompson, Eric Darcy

As a global medical and occupational healthcare provider, Remote Medical International (RMI) has been battling Covid-19 offshore for the past year. Through its work mobilizing “Covid Copters,” as well as providing specialist medical support to some of the world’s most remote locations, RMI provides unique insight into activities since the pandemic first hit.

An Internet of intelligent things for more sustainable operations

Abuzar Manager, Gian-Marcio Gey

Edge computing, AI and machine learning, and IIoT technology serve as key enablers to deliver safer and more environmentally sustainable operations by reducing human and carbon footprints, while increasing operational efficiency and productivity.


Saving billions with bots

Craig Fleming

The combination of artificial intelligence, machine learning and the industrial internet of things is enabling remote operations and automation capabilities, leading to greater adoption and proliferation of intelligent oilfield operations.
