Abstract:
The present invention provides a process for the microbiological production of hydrogen from a hydrocarbon-rich deposit, said process comprising the step of modifying the composition of the deposit by the introduction into the deposit of at least one non-native hydrogen producing microorganism selected positively to diversify the microbiological abundance of hydrogen-producing microorganisms in the deposit and for the preferential production of hydrogen over methane.

Abstract:
Systems and methods for an integrated wellbore stress, stability and strengthening analysis are disclosed. An integrated geomechanical tool can be used to analyze and evaluate stress along the length of the wellbore to identify a safe drilling mud weight window and help identify troublesome zones in the wellbore. Fracture length may then be predicted in the identified troublesome zones by using a stress tensor calculated during the stress analysis. The calculated fracture length may be used to perform a strengthening analysis. After performing strengthening analysis, mud loss may be predicted based on predicted fracture size calculated during the stress, stability and strengthening analyses.
