Coupled full-field hydrodynamic–geomechanical assessment of sequential CO2 cushioning and cyclic hydrogen storage in a UKCS depleted gas reservoir
Abstract
Hydrodynamic and geomechanical evaluations of underground hydrogen (H 2 ) and carbon dioxide (CO 2 ) storage are performed using a full-field history-matched model of a depleted gas reservoir located in the Southern North Sea (SNS) of the UK Continental Shelf (UKCS). H 2 injection and production (optimised rates 120 MMscf/d and 78 MMscf/d, respectively) in cyclic mode for a period of 9 years following the initial 2-year CO 2 cushion gas injection period resulted in 82 % H 2 recovery in the cyclic scheme. The geomechanical investigations revealed minor vertical displacement (uplift) less than 0.35 ft, low slip tendencies (
