Key Ideas
- The pilot trial aimed to economically develop tight and hard-to-recover formations using active hydrogen.
- An innovative approach of utilizing active single-atom hydrogen power to enhance near-wellbore permeability was deployed.
- Customized hydroreacting agents were used for in-situ hydrogen generation, thermal energy production, and enhanced gas and acid vapor creation.
- The case study in West Kuwait focused on revitalizing a carbonate, multifractured tight reservoir facing low recovery factors.
The paper discusses a pilot trial focused on developing tight and hard-to-recover formations using active hydrogen stimulation. The objective was to provide an economic solution for challenging assets with low recovery factors and high costs of conventional stimulation technologies. The approach involved utilizing active single-atom hydrogen to enhance near-wellbore permeability through a unique chemical reaction between hydroreacting agents. This reaction led to the generation of thermal energy, active hydrogen, and other gases and acid vapors, customized for each field's requirements. The paper highlights the West Kuwait business case, targeting the M formation in a carbonate, multifractured tight reservoir with declining recovery factors. The innovative use of active hydrogen aimed to improve production rates and overall recovery from such challenging formations. The technology described in the paper showcases a promising approach to stimulate hard-to-recover formations efficiently and economically, potentially offering a solution to operators dealing with similar reservoir challenges.
