A Hydrate Researcher is needed to characterize pressure cores retrieved from the GOM from an expedition in 2017. The focus of characterization is on measuring compressibility, anisotropic permeability, mechanical strength, and large-strain behavior without any pressure-temperature disturbance on the initial condition during the entire course of handling and characterizing pressure cores. The pressure core characterization will be performed using a new tool set, pressure core analysis and X-ray computed tomographic (PCXT) visualization tools, newly developed at NETL. The task is a combined effort characterizing the cores for those above-mentioned physical properties at both core-scale and pore-scale in conjunction with high resolution X-ray CT pore-scale visualization. The physical property measurements will enhance the understanding of hydrate interactions with geologic matrix controlling hydrological and geomechanical properties of MHBS. Using NETL’s unique sub-coring assembly of the PCXT, the unprecedented effort of pore-scale observations of the undisturbed, natural MHBS is to obtain the first direct, non-destructive observation of hydrate pore habits and interactions with sediment matrix using a micro-CT scanner at the NETL Morgantown, West Virginia, site. The pore-scale observations will help relations between physical properties at two different scales, and eventually to assess root causes of soil skeleton deformation and multiphase fluid behavior under production at reservoir scale.
Primary Responsibilities Include:
- Characterize pressure cores retrieved from the GOM from an expedition Present ideas and results to the research team
- Contributing to future research planning and assisting with proposals.
- Working independently and collaboratively with members of the research team to meet milestones and deliverables.
- Assisting or leading efforts in writing research papers and creating conference presentations.
- A minimum of a Ph.D. in Civil Engineering, Chemical Engineering, Mechanical Engineering, or Hydrogeology is required, and less than 1 year of experience.
- Previous experience working in hydraulic/geomechanical analysis on soil/rock sample, high pressure/low temperature experiments, x-ray CT scanner, and gas/liquid chromatography analysis.
- Must be familiar with laboratory instrument including pressure chamber, high pressure pumps system, monitoring data logging system, gas chromatography, and X-ray micro CT scanner.
- Previous work experience in pressure core analysis and automated data collection using Labview.
