Job Description:

Leidos is seeking a Geochemical Researcher to support the Onshore Unconventional Resources team. The team is developing fundamental knowledge of organic and oxidation-reduction geochemical reactions for increasing hydrocarbon recovery from unconventional oil and gas reservoirs.

The candidate will conduct; analytical, experimental, investigative and other fact-finding work using standard scientific approaches and techniques to support principal scientific researchers, observes, calculates, records and interprets the results of tests and analyses, and designs, constructs, modifies, calibrates, operates and maintains equipment used for these purposes or devised as a result of the work.

Primary Responsibilities Include:

1)Develop data sets and interpretations of data for biogeochemical interactions in unconventional oil and gas reservoirs. Demonstrated knowledge and experience with all the following analytical techniques is required:

  • Ion chromatography-based methods for fluids with high total dissolved solids concentrations;
  • Measurement of changes in electron donating and accepting capacity of reacted shales and fracturing chemicals using electrochemistry-based techniques;
  • Design, fabrication, and field and laboratory testing of redox microelectrodes sensitive for measuring dissolved iron and sulfur species in complex environmental fluid matrices;
  • Analysis of oil and gas related samples and associated data interpretation with liquid chromatography quadrupole time-of-flight mass spectrometry.

2)Familiarity with appropriate technical and safety requirements, and an ability to perform, field-based collection of geologic fluid and solid samples from oil and gas well sites, produced water facilities, natural spring water sites, and other locations as determined.

3)Maintenance and coordination of laboratory capabilities associated with the Pittsburgh site Redox Geochemistry Laboratory, which include the following:

  • Operation and maintenance of electrochemistry-based analytical equipment (glassy carbon electrode-based experimental work; field-deployable Au-Hg amalgam electrodes)

4)The candidate will prepare technical reports on project scope, milestones and conference/workshop presentations to disseminate research findings, activities, operations, and future initiatives to industry, academic and government stakeholders is a requirement for this position.

5)Period status reporting (weekly/monthly/quarterly/annually) is required to update project managers and customers.

6)The candidate will participate in group meetings. Group meetings are designed to allow the applicant to discuss current research and promote discussion with fellow researchers. The manager will request the applicant to provide a PowerPoint presentation for group meetings. The frequency of these presentations is generally once every 6 months but can occur at a higher rate.

7)This position will require extensive interface with customers and potential collaborative partners, so excellent verbal and written communication skills are required. The complexity of information to be managed will require excellent organization skills and attention to detail.

Required Qualifications:

  • Bachelor’s degree in a science or science-related field (e.g., biology, chemistry, economics, geology, mathematics, physics) and 5 years of job-related experience or a master’s degree.
  • Excellent communication skills and a willingness and interest to collaborate in an interdisciplinary team environment to drive towards overall project and team objectives is also required.
  • Demonstrate experience in mentorship of early-career scientists and/or students is required.

Preferred Qualifications:

  • A PhD degree in Earth Science with experience in environmental organic and oxidation-reduction geochemistry with educational experience in geochemical weathering.
  • The prospective employee would be familiar with working in a Research and Development setting
  • The candidate would have experience conducting research at a GOGO (Government owned Government operated) lab.
