ABERDEEN - CURTIN ALLIANCE JOINT PHD OPPORTUNITY:- Unconventional reservoir imaging and geological interpretation in porous, heterogeneous environment via integrated seismic, petrophysical, and mineralogical techniques
Imaging through heterogeneous sequences suffers from the shading of underlying reflectors caused by the high-velocity and high frequency absorption of the volcanic rocks. This is paired with the presence of laterally varying attenuation, which causes defocusing and scattering in multiple internal reflections, high noise levels” in the form of incoherent scattering patterns, and anomalous attenuation. The supervisors of the team have tackled these challenges separately by:
a) the development of novel seismic and rock-physics imaging techniques better apt at imaging sub-basaltic and intra-basalt sequences (De Siena, Vialle) in particular transforming attenuation and scattering from an hindrance into an imaging tool (De Siena);
b) the development of novel petrophysical and mineralogical techniques suitable for accurate measurements of statistical properties of rocks and understanding of how the rock matrix interacts with fluids/CO2 (Putnis, Healy);
c) the establishment of a rock-physics lab comprising an OGIC-funded HP/HT rock deformation and seismic apparatus, suitable for joint seismic and deformation measurements on heterogeneous rock samples (Healy).
The candidate will address the challenge of linking seismic and petrophysical/mineralogical parameters of industrial interest in the lab, strongly improving fracture and fluid flow characterization and understanding of CO2 sequestration processes. . He/she will then proceed to the development of computational tools and application at field scale, eventually leading to a proper “pore-fluid pressure tomography” of the reservoirs. This can be achieved without the need of collecting new seismic offshore data, and with strong impact on the reduction of risk associated e.g. to drilling.
The successful candidate will have, or expect to have, a UK Honours Degree (or equivalent) at 2.1 or above in Physics or Geophysics along with a Master degree in the same subjects.
The other supervisors on the project are Professor Andrew Putnis, Geochemistry, Curtin University and Dr Stephanie Vialle, Geophysics, Curtin University
The start date for the project is to be agreed by the supervisors but no later than 30 April 2018.
