RESA III - COMobility and Subsurface Transport

RESA III - CO2 Mobility and Subsurface Transport Overview

This position is a one‑year, fixed‑term, in‑person role located at the J.J. Pickle Research Campus in North Austin. The successful candidate will join a small, highly integrated research cohort at the Bureau of Economic Geology (BEG), University of Texas at Austin, tasked with pioneering innovative experimental and modeling techniques that bridge laboratory‑scale physics and field‑scale implementation.

The primary objective of this role is to quantify and simulate the complex transport dynamics, mobility, and structural interactions of gases and fluids within tight, stressed reservoir matrices of shale rocks (unconventional reservoirs). The role combines rigorous laboratory operations—measuring effective permeability, diffusion, and adsorption in rock samples—with analytical or numerical modeling to investigate how dynamic stress‑sensitivity governs macro‑scale reservoir performance.

• Core Transport Experiments:
  Operate and modify advanced gas expansion/liquid transient flow systems to measure CO₂ (gas and supercritical phase) mobility, effective permeability, molecular diffusion, and adsorption.
• Geomechanical & Stress Evaluation:
  Quantify rock‑fluid interactions and transport degradation under dynamic net confining stress environments to evaluate reservoir stress‑sensitivity.
• Compositional Reservoir Simulation:
  Upscale laboratory‑derived petrophysical, diffusion, relative permeability, and stress‑dependent parameters into compositional reservoir models to perform robust sensitivity and production forecast studies.
• Strategic Integration:
  Work closely with the lab formulation team to translate fluid‑interface mechanics into numerical transport constraints, preparing technical frameworks for upcoming field‑scale pilot deployments.

MS in Petrophysics, Petroleum Engineering, Geomechanics, Chemical Engineering, Geosciences, or a closely related geosystems discipline and at least 2 years of experience. Proven experimental expertise in high‑pressure core experiments, petrophysical measurements (effective permeability, porosity), or fluid transport phenomena. Deep fundamental understanding of fluid transport mechanisms in tight/unconventional formations (diffusion, adsorption, Darcy vs. non‑Darcy flow). Strong capability in data analysis, scripting, or laboratory automation (Python, MATLAB, or LabVIEW).

A PhD in the required disciplines is strongly preferred. Extensive proficiency with commercial compositional reservoir simulators (e.g., CMG GEM, ECLIPSE) and a proven track record of history‑matching laboratory core‑floods. Experience or strong fundamental training in Geomechanics (stress‑strain relationships, fracture conductivity, or rock mechanics). Experience utilizing digital rock physics, image analysis, or CT scanning to evaluate multi‑phase flow displacement.

$72,000 - $76,000 per year.

• May work around chemical fumes and standard office conditions.
• Repetitive use of a keyboard at a workstation; requires manual dexterity.
• May require occasional weekend, overtime, and evening work to meet deadlines.
• May involve intrastate, interstate, and international travel.
• May involve fieldwork as necessary.
