PhD fellow in Sedimentology

Applications are invited for a PhD fellowship/scholarship at Graduate School of Science and Technology, Aarhus University, Denmark, within the Geoscience programme. The position is available from 1 February 2018 or later. The position is open within the frame of the LOCRETA research consortium, funded by the Danish Hydrocarbon Research and Technology Centre (DHRTC). The deadline for application is the 1st of November 2017.

Title: Microfacies and petrographic properties of the Danish Lower Cretaceous

Research area and project description:

We are looking for a motivated PhD candidate in Sedimentology, Stratigraphy and Geochemistry to work on the offshore Lower Cretaceous of Denmark. The main objectives of this PhD thesis are to provide detailed analyses on the stratigraphic and lateral evolution of microfacies with the Danish North Sea, as well as the evolution of the clay mineral content and types within this basin. Indeed, despite the fundamental role of understanding petrographic and microscopic properties in reservoir rocks for improving recovery, drilling and operations, there is currently only limited information available on the microfacies and petrographic properties of the LC "chalk" reservoir. This limits our ability to understand the environmental conditions under which the LC sediments were deposited as well as their diagenetic history. The acquisition of these data is thus fundamental for building an integrated depositional model and improving reservoir models.

Currently, the microscopic rock parameters, notably the type and amount of clay content, as well as any potential spatial and stratigraphical heterogeneity in these parameters, is vastly unknown. This study is build upon these concerns and aims at providing a comprehensive understanding on the microscopic character of the Danish Lower Cretaceous.

This PhD thesis will be performed in close collaboration with a PhD thesis hosted in Copenhagen University dealing with macroscopic sedimentologic aspects of the Danish Lower Cretaceous, and implies collaboration and interactions will all the members of the LOCRETA consortium. A willingness to work as part of a larger research group, as well as a positive attitude toward communications/interactions with consortium partners is therefore a prerequisite.

Your scientific task will be:

  • Samples Lower Cretaceous cores stored at the Maersk core repository in Copenhagen
  • Prepare the samples for geochemical analyses
  • Perform X-ray diffraction analyses
  • Analyses sedimentary thin sections for their microfacies and microtextures
  • Interpret your dataset
  • Publication of relevant results in international scientific journals
  • Participate to national and international conferences
  • Collaborate with LoCreta group members from AU and other research units through Denmark

Qualifications and specific competences:

Candidates should have a Master's degree in Geology or Geoscience, with a specialization toward sedimentology or sedimentary geochemistry, or any relevant field of study. Preferably, the candidates would have experience in microfacies and clay mineralogy analyses, as well as basic knowledge about carbonate diagenesis. Strong interest in microscopic and geochemical analyses is therefore needed. The candidate should have good command of oral and written English, be able to write scientific publications, be willing to contribute to undergraduate teaching, and should be enthusiastic about working in an interdisciplinary international academic environment.

Place of Employment and Place of Work:

The PhD will be enrolled at Graduate School of Science and Technology (GSST), Aarhus University, and the place of work will be Department of Geoscience, Høegh-Guldbergs Gade 2, DK-8000 Aarhus C, Denmark.

Application procedures

Before you apply

Information and attachments:

Please be aware that you must have all relevant appendices, attachments, addresses for referees, etc. ready when you apply, as the entire application must be uploaded to the system in one go.

Documentation of language skills:

The English language requirement at Graduates School of Science and Technology is comparable to an "English B level" in the Danish upper secondary school ("gymnasium").

English language qualifications comparable to an "English B level" is documented by one of the following tests:

  • TOEFL test, minimum score: 560 (paper-based test) or 83 (internet-based test). Aarhus University does not accept the TOEFL ITP test. Aarhus University's TOEFL code is 8935. You must request that the test centre send your test results to Aarhus University, in order to enable verification of your test results.
  • IELTS (academic) test, minimum average score: 6.5 points
  • Cambridge English Language Assessment:
    Cambridge Certificate of Proficiency (CPE)
    Cambridge English: Certificate of Advanced English with grade A,B or C (CAE)
    Cambridge English: First Certificate with grade A (FCE)

When to take the test and how to upload the documentation:

The test result must not be more than two years old at the time of application.

The English language test should be taken before applying for admission and uploaded under "language skills documentation" in the online application form.

It is possible to apply for admission before you have taken the test. In this case documentation stating that you have signed up for a test (please state expected submission date) must be uploaded. If the test result is not part of the original application the test result is to be sent to no later than one month after the application deadline.

The following applicants are exempted from documenting their English qualifications/taking a test:

  • Applicants with citizenship from the following countries: Australia, Canada, Ireland, New Zealand, United Kingdom, United States, or one of the Nordic countries (Denmark, Finland, Iceland, Norway or Sweden).
  • Applicants with a Bachelor's or Master's programme completed in Australia, Canada, Ireland, New Zealand, United Kingdom, or United States. In this case, please upload your Bachelor's or Master's diploma under the section "Language skills documentation".
  • Applicants with a Bachelor's or Master's programme completed at Aarhus University for which the requirement was English B level at the time of admission. In this case, please upload your Bachelor's or Master's diploma under the section"Language skills documentation".
  • Applicants able to document that English was the language of instruction during the whole period of their Bachelor's and/or Master's programme. This must be documented by uploading an official document from the institution stating this under "language skills documentation". The onus is on the applicant to provide this information as GSST will not pursue information regarding language of instruction for any programmes or institutions.

The programme committee may request further information or invite the applicant to attend an interview.
