Schlumberger
Key Responsibilities:
- Comprehensive Knowledge of LWD and Wireline Technologies:
+ Possesses strong working knowledge of both Logging While Drilling (LWD) and conventional Wireline logging technologies, including tool principles, operational workflows, and limitations.- Logging Program Design & Operational Support: Capable of designing effective and fit-for-purpose logging programs tailored to specific reservoir evaluation needs. This includes selecting appropriate logging tools, optimizing run sequence, and defining operational contingencies.
+ Quality Control (QC) of LWD and Wireline Logs:
+ Proficient in executing rigorous quality control of raw and processed log data. Identifies and corrects tool-related artifacts, depth mismatches, environmental effects, and signal noise. Ensures integrity of final deliverables for both open hole and cased hole environments through statistical, visual, and cross-disciplinary validation techniques.
- Advanced Petrophysical Interpretation – Probabilistic and Deterministic: Demonstrates strong ability in both deterministic and probabilistic log analysis workflows. Skilled in using a range of log types—including conventional triple combo logs, elemental spectroscopy, Nuclear Magnetic Resonance (NMR), X-ray Diffraction (XRD), and core measurements—for accurate quantification of porosity, saturation, permeability, and mineral composition.
- Multi-Source Data Integration for Petrophysical Modeling: Integrates diverse datasets including core measurements (RCAL/SCAL), mud logs, well test data, production logs, and image logs to develop comprehensive and geologically consistent petrophysical models.
- Spectroscopy and NMR Data Analysis Expertise
+ Demonstrates strong capability in processing, interpreting, and integrating advanced elemental spectroscopy and Nuclear Magnetic Resonance (NMR) log data for detailed reservoir characterization.
- Advanced Acoustic Log Processing and Interpretation: Solid command over the processing and interpretation of full waveform acoustic data. This includes:
+ · Compressional and Shear Slowness Analysis: Derives accurate dynamic elastic properties for rock physics modeling, geomechanical studies, and fluid substitution. Ensures proper borehole compensation and anisotropy detection.
+ · Stoneley Wave Analysis: Applies Stoneley slowness and amplitude attributes for permeability prediction, borehole condition evaluation, and identification of open fractures.
+ · Fracture Characterization: Identifies natural and drilling-induced fractures using amplitude, travel time, and waveform shape analysis. Integrates findings with borehole image logs and core data.
+ · 2D Anisotropy Analysis: Quantifies vertical and horizontal slowness variations to assess transverse isotropy, shaliness effects, and stress orientation.
+ · 3D Anisotropy Interpretation: Evaluates orthorhombic or triclinic anisotropy in complex reservoirs (e.g., fractured carbonates or tight gas formations), contributing to fracture modeling and well placement decisions.
Qualifications & Skills:
+ Education: Bachelor’s or Master’s in Geosciences, or a related field. Experience: Minimum 6+ years in formation evaluation in OH and CH environment
+ Technical Skills: Expertise in Techlog software will be preferred. Analytical Skills: Strong understanding of rock mechanics, stress modelling, and wellbore stability. Problem-Solving: Ability to identify and mitigate drilling/completion challenges.
+ Teamwork and Cross-Disciplinary Integration: Ability to work in multi-disciplinary teams and contribute to collaborative work environment.
+ Bachelor Degree (Range of Majors/Geoscience , Geology , Petrophysics etc...)
+ minimum 5 of years of experience.
