Radial Jet Drilling technology is known to enhance onshore geothermal as well as oil and gas production. DHRTC research shows that it can also increase production in the Danish North Sea, although more technology development is needed.
Radial Jet Drilling (RJD) technology has the potential to increase oil and gas production from most of the existing wellbores in the Danish North Sea, where up to 70 percent of the oil in the underground are ’locked’ or bypassed in the very tight chalk.
This is the main conclusion of a DHRTC research project assessing the impact on production, and analyzing the stability of jetted radials in the Danish North Sea fields.
DHRTC is developing a prototype for designing and optimizing the placement of jetted radials. This work will be completed in early 2020, at which point the prototype will formally pass technology readiness level 3
“At that stage, we have documented the concept and value potential of the technology for the Danish North Sea fields. Still, in order to reach a level where it becomes feasible to apply the technology by jetting radials in the complex wells in the Danish North Sea fields, further development and testing are required. It will take further engineering efforts from Total and suppliers from the industry to make the technology ready for offshore use,” says Programme Manager Anders Bak-Jensen, DHRTC.
“The ultimate goal is to use the radial jetting technology without rig support at all, because that is the only way it makes economic sense for us offshore. The main areas requiring further development are downhole manipulation of the tool and deployment of the equipment while maintaining pressure control,” explains Michael Pitts, Lead Production Technologist, Total.
“We have had very good collaboration with Total and other partners from industry and research in working with this technology and bringing it towards the prototype level. It is now time for us to hand this prototype over to Total to consider the value in bringing the technology offshore,” ends Anders Bak-Jensen.
