After successfully completing the first phase of this project, another OGIC collaborative research project has been agreed between Varel and Centre for Applied Dynamics Research at University of Aberdeen for continuation of the phase I.
The project which has been launched on June 15st, 2018 is on developing calibrated models of bit-rock interaction with perspective of developing a new technology for hybrid drill-bits under supervision of Professor Marian Wiercigroch.
This project aims to gain better understanding of the mechanics of force generation and its relationship with the drilling parameters and ultimately to improve the PDC bits. The plan is to develop bit-rock interaction models of single cutter/blade PDC at variable depths of cut. These models will be calibrated and validated by extensive experimental tests. These models are vital for design of a new technology, Varel hybrid drill bit with cutting structure combining shearing and gouging action suited for much greater longevity and efficiency for chert and fractured granite reservoirs.
Describing the first phase of the project, Jason Marchant, Varel UK District Manager North Sea, said to OGIC: “Aberdeen University Engineering have been excellent partners in this project which, in its approach, has broken new ground and led to several paths of research worthy of further investigation”.
Professor Marian Wiercigroch added: “This has been highly rewarding experience for the University to work with the Varel team on such a fundamental and practically important project. The findings should facilitate development of a new mathematical model for interactions between drill-bits and drilled formations and ultimately lead to designs of highly competitive new generation drill-bits”.
Oil and Gas Innovation Centre (OGIC) is an innovation support organization that helps companies access the research and development capability within Scotland’s university community. OGIC’s work directly contributes to the twin goals of maximising economic recovery from the UK continental shelf and supporting the development of the supply chain through bringing new products and services to the UK and international markets.
