Gravity Delve Project to Investigate Use of Quantum Gravity Sensors Down Boreholes in Oil & Gas Sector

Installation for oil at night

( The Gravity Delve project, funded by Innovate UK, brings together academics from the UK Quantum Technology Hub Sensors and Timing, which is led by the University of Birmingham and Nemein Ltd, with the aim of investigating the benefits and challenges associated with using quantum gravity sensors down boreholes in the oil and gas sector.
Quantum cold-atom sensors designed to operate on the surface will be able to detect and monitor objects beneath the ground better than any current technology. However, little attention has been paid to-date to the benefits that borehole deployable quantum gravity sensors could have. Gravity Delve aims to address this.
Nemein is developing borehole deployed equipment primarily focussed on energy harvesting and environmental sensing. The new technology will enable the quantum sensor developed by the University of Birmingham to venture out of the lab and into the extremely harsh downhole environment.
Borehole applications to be investigated in the project will include carbon capture and storage (CCS), and hydrocarbon and geothermal reservoirs. Existing techniques for reservoir optimization include conventional microgravity, electrical and nuclear logging. These techniques however are limited by sensitivity, resolution and cost. Gravity Delve is investigating how a commercially relevant quantum device could replace or enhance current technology to optimize CCS reservoirs, minimize the environmental impact from hydrocarbon extraction, and enhance the transition from fossil fuels to renewable energy such as geothermal.
