Developing new environmentally-friendly solutions for well plugging and abandonment (well P&A)

Hydrocarbon leakage from subsurface environments has been a critical concern for groundwater resources and atmospheric pollutions. Methane leakage from hydraulically fractured shale reservoirs and oil and gas leakage from offshore abandoned wells raised the issue that well integrity and current remedial solutions may not be adequate to overcome them.

In this study, new environmentally friendly chemicals that can withstand the harsh conditions (high temperatures, corrosive environments, and geological stresses) will be formulated and tested in laboratories to simulate downhole conditions. The new materials have low toxicity compared to the current commercial ones; furthermore, they may have the potential to block fractures and fissures through different in-situ processes. Different tests using high tech facilities such as X-Ray CT scan, rheometer, and stress analysis equipment will be conducted to characterise the new chemicals to be used for well plugging and abandonment (well P&A). Once the physical and chemical properties of the new chemicals (surface wettability, solubility, adhesiveness, and stress/strain properties) are determined, they will be tested on prototypes of shale reservoirs and mature wells to justify the application of such chemicals for pilot tests.

The successful candidate should have (or expect to achieve) a minimum of a UK Honours degree at 2.1 or above (or equivalent) in Petroleum Engineering, Chemistry or closely related degrees.
