In summary, regulations need to be updated to the current needs of the industry to allow for efficient improvement of wellbore integrity. The updates to regulations should be validated by data gathered following the scientific process. This is different from industry best practices. Industry best practices can be the result of trial and error and may not have been validated by science. The oil and gas industry is still in its infancy when conducting and documenting science on wellbore leakage. In addition, there is currently no process to present validated science to update regulations. This lack of a process to modernize the regulations through the use of science is a significant barrier to reducing wellbore leakage.
