I develop and validate geomechanics-informed structural analysis workflows for oil & gas problems by combining rigorous literature synthesis with reproducible computational testing and publication-focused writing. I document how evidence is identified, selected, and synthesized so my reviews and resulting conclusions are auditable and reusable (PRISMA 2020 principles).
Core responsibilities:
- Define research questions that connect field-relevant failure modes (e.g., wellbore stability and casing integrity) to tractable modeling and data needs.
- Run systematic literature reviews with explicit eligibility criteria, defined information sources, and a documented selection process (screening + reasons for exclusion) consistent with PRISMA 2020 type reporting.
- Extract and normalize key study variables (constitutive model choices, calibration tests, boundary conditions, uncertainty treatment) into structured datasets for comparison and synthesis.
- Critically appraise evidence quality/limitations (e.g., credibility of assumptions, validation scope, sensitivity coverage) and make uncertainty explicit in the synthesis.
- Build code to test claims from the literature (verification/benchmarking, parameter studies, sensitivity/robustness checks) and keep workflows reproducible (version control, scripted pipelines).
- Write and submit peer‑reviewed papers, including transparent Methods/Results sections that allow others to replicate the review and computational experiments.
