Well integrity under hydraulic pulses

This PhD will examine the integrity of the well casing and cement containment under conditions of pulsed flow within the well. Under pulsed stimulation, it is possible that wells might deteriorate faster than in conventional working conditions.

Eligibility for RCUK studentships

  • Research Council (RC) fees and stipend can only be awarded to UK and EU students and not to EEA or International students.
  • EU students are only eligible for RC stipend if they have been resident in the UK for 3 years, including for study purposes, immediately prior to starting their PhD.
  • If an EU student cannot fulfil this condition then they are eligible for a fees only studentship.
  • International students cannot be funded from RC funds unless they are ‘settled’ in the UK. ‘Settled’ means being ordinarily resident in the UK without any immigration restrictions on the length of stay in the UK. To be ‘settled’ a student must either have the Right to Abode or Indefinite leave to remain in the UK or have the right of permanent residence in the UK under EC law. If the student’s passport describes them as a British citizen they have the Right of Abode.
  • Students with full Refugee status are eligible for fees and stipend.

Project Details

Oil and gas wells are designed and engineered to ensure that they are adequate to stop contaminant leakage to the ground surface or water resources.  This PhD will examine the integrity of the well casing and cement containment under conditions of pulsed flow within the well. Under pulsed stimulation, it is possible that wells might deteriorate faster than in conventional working conditions. This project aims to evaluate the response of oil and gas casing and cement to the hydraulic pulses, as well as serviceability and integrity of the wells under pulsed stimulation. Specifically, the project will address the issues related to corrosion of steel casing, fatigue of steel casing, cracking/de-bonding of cement, etc. Both quantitative and qualitative approaches will be employed to present an integrated framework for evaluating the well integrity under hydraulic pulses, considering all the major deterioration forms.

Based at the University of Strathclyde - this project directly aligns and contributes to strategic areas of the UK funding councils, providing knowledge of interest to academia, industry and regulators. The research builds on critical research mass in CEE department in Oil/Gas and the student will join a large group of 10+ PhDs and PDRA researchers. The PhD will prepare the student with a set of skills that will assist in the assessment and evaluation of well integrity and will inform industry and practising engineers with regard to the deterioration and serviceability of the wells.  

Funding Details

Home fee, standard EPSRC stipend plus £5k per year project costs

Non-home students will have to provide the excess fees and may not be eligible for a stipend (see UKRI studentships page)
