Job Description

Responsibilities

• Splice overlapping log runs into single composite curves, perform rigorous depth alignment and tie-in across log suites to eliminate depth discrepancies.
• Execute structured quality control (QC) protocols on field-wide well logs across all acquisition vintages, implement normalization algorithms to reconcile tool response variations, apply environmental corrections for borehole conditions, and resolve data anomalies to deliver a standardized, depth-consistent petrophysical database.
• Perform detailed quality assurance (QA) audits of petrophysical analyses to identify critical gaps in log interpretation, core calibration, and fluid distribution then deliver targeted solutions that enhance subsurface model confidence.
• Conduct integrated fluid distribution study incorporating well logs, mud-logs, pressure/sampling data, DST, and production data to define fluid, identify discrete pressure compartments, and assess reservoir connectivity for optimized field development.
• Perform core-log integrated reservoir characterization by classifying reservoir intervals into discrete hydraulic flow units (HFUs) using Flow Zone Indicator (FZI) or Reservoir Quality Index (RQI) methodologies, develop HFU-specific porosity-permeability transforms calibrated to core data, apply regression analysis to propagate rock properties into un-cored wells, and derive saturation-height functions for each HFU to populate water saturation distributions in the 3D static reservoir model.
• Execute integrated deterministic and probabilistic petrophysical modeling utilizing corecalibrated algorithms to systematically compute shale volume, porosity, permeability, and water saturation across all intervals, then apply cutoff criteria to quantify net sand and net pay volumes for in-place estimation.

Requirement

• Minimum 15 years of active experience in petrophysics with a proven track record in both development and production settings. In which minimum 5 years working with operator oil company.
• Conduct minimum one (1) petrophysical evaluation in integrated reservoir characterization studies (FDP/FDAP or FFR) in the last five (5) years.
• Extensive experience in building Saturation-Height Functions (SHF).
• Extensive experience in both open-hole and cased-hole logging interpretation and operation supports.
• Expert-level mastery of Techlog software.
• Demonstrate ability to communicate and translate complex petrophysical concepts into actionable insights for non-experts.
