January 2020 – AkerBP Norway run 7″ AVS

 

 

   

 

AkerBP  select the 7″ AVS for their Valhall F11 well. This was a sidetracked well that has tremendous stick / slip. The AVS was run in the 8 1/2″ BHA for drilling out the 9 5/8″ liner shoetrack and drilling ahead. The AVS was run successfully in Splitflow mode but suffered a problem when trying to go into Bypass for POH. Later investigation showed the MEMS gyro PCB had suffered a micro fracture meaning the gyro, which reads RPM was making spurious readings. The micro fracture was due to an induced stress i.e slight bending when the AVS was being assembled in IDT’s assembly room. Procedures have been changed to ensure this does not happen again and the introduction of the V2 software, which allows downlink via multiple methods including pump cycles, pump duration and differential pressure, means a downlink can be made even if the Gyro fails.

 

 

 

Archer and IDT sign Global Collaboration Contract

 

 

               

 

Archer and IDT sign a Global collaboration contract for marketing and logistical support. Archer are a global oil service company with a superb and diverse product lines ranging from Modular rigs, speciality well abandonment plugs & packers, well bore cleaning and electric wireline. In addition they have a fantastic R&D and technology centre where IDT technology can be potentially deployed into many new developments. Through this agreement, IDT are already making inroads into the Middle East with presentation having been delivered to ADNOC and other Operators in the region.

 

 

November 2019 – OGTC sign off on the 7″ AVS and DEAP Technology

 

 

Malcolm Banks (foreground), OGTC Wells Solution Manager visits IDT’s assembly room in Sheffield to close out the 7″ AVS / DEAP project. Mark Booth, IDT Senior Development Engineer shows Malcolm the DEAP V2 software and runs through the activation process on the test bench. A full function test on the flow loop was conducted shifting the AVS into all its positions successfully.

 

 

June 2019 – 7″ AVS MK4 Ready for testing

 

     

 

The MK4 7″ AVS has completed its design, manufacture and build and is now ready for extensive testing on the C&W Flowloop at our Sheffield facility. The major differences of the MK4 to previous versions is the overall packaging which has reduced the length by over 1m. We have a revised selector ring assembly, pre fabricated encapsulated wiring harness, improved electronics increasing battery efficiency, numerous mechanical enhancements to improve efficiency and reliability. In addition, the tool can now be programmed with the V2 software from a single external access port. This delivers reduced service and maintenance costs. A huge thanks to the OGTC and Lundin Energy for their support in delivering the MK4.

 

 

June 2018, AVS Run with OMV / Halliburton

 

 

       

 

Halliburton selected the AVS as part of their Directional drilling BHA for a horizontal test well drilled at Ullrig in Stavanger. 10 3/4″ casing was set horizontally with a 12 deg/30m build up section. There was then a planned 9.5″ horizontal hole section. The AVS was picked up and drilled out the shoetrack with no issues. A remedial cement job on the shoe to get the required shoe strength, was then conducted. the AVS was racked back in the derrick for a week before being picked up again to drill out cement. The BHA became stuck inside the shoe with cement debris and took 4 hrs to jar free. The AVS was downlinked in less than 6 mins and opened to Splitflow position to jet the shoe track area. This was done successfully with no issues. A great test of the AVS function and integrity. When the log from the ASV was downloaded it showed in excess of 50g shocks (max we can record) but perfect functioning of the tool.

 

 

June 2018, Oil & Gas Technology Centre, Aberdeen and Lundin Energy, Oslo fund AVS and DEAP development

 

 

Exciting news as the OGTC, Aberdeen and Lundin Energy, Oslo part fund development of the smaller 7″ AVS electronic multi position circulating valve including the V2 Software. At the core of the AVS is the Downhole Electronic Activation Platform  or DEAP that provides the unique ability to activate any downhole tool using any of its sensors. MEMS gyro, Accelerometers, proximity sensors and pressure sensors. The V2 software allows the tool to be programmed with multiple options for downlinking.

IDT plan to have the first of the 7″ AVS MK4 tools for trial with Lundin by the end of 2019.

 

     

 

 

 

March 2018, AVS run for Lundin Energy, Luno 2 well, Norway

 

 

 

 

The Luno 2 exploration well drilled by Lundin Energy with the COSL Innovator semi submersible, was the latest trial for the 8″ AVS electronic multi position circulating valve. This was the latest MK3c version with revised seals and upgraded internals. The tool was programmed to respond to a simple downlink consisting of a reference RPM followed by a pump cycle sequence. Downlinks take around 6 minutes to complete. The AVS BHA was run to 1100m, the downlinks sent to change into Splitflow and then to Bypass. The downlinks were received but due to a sticking piston, later found out to be excessive seal friction, the tool did not start functioning until later in the sequence. This issue has now been revised and Lundin signed a 2 year contract with IDT that will allow live well testing of the smaller 7″ MK4 AVS when it becomes available at the end of 2019
