Project outline

Many deep marine clastic accumulations are built by alternations of remobilization events of varying rheology, including turbulent, relatively dilute flows, such as turbidity currents, laminar, relatively concentrated flows, such as debris flows and rheologically heterogenous hybrid flows. These different flow types leave deposits with a characteristic morphology –debris flows typically build mounded deposits with rugose tops and relatively abrupt margins whereas turbidity currents commonly deposit flat-topped, gently tapering deposits (or may leave channels of erosional, aggradational or mixed character). Different flow types therefore (1) variably condition the substrate encountered by subsequent flows, and (2) respond to bed topography in different ways. Thus the sequence of flow types that build any particular system may significantly affect the final architecture. A further complicating factor arises when flows from different source areas deposit in the same location.

This studentship will concentrate upon the Britannia Sandstone Formation in the Outer Witch Ground Graben of the North Sea, which comprises SSE-dispersing Upper Aptian deep-water sandstones that thin and pinch out against a palaeoslope formed by the Fladen Ground Spur to the North. The formation has been extensively drilled and cored on and around the Britannia gas condensate field. This study will build upon three earlier studentships, in which both the upper and lower sections of the reservoir have been re-interpreted revealing remobilization effects at a variety of scales linked to instability associated with the confining Fladen Ground slope. The goal of the new studentship is to log, describe and interpret the remaining middle reservoir section, linking and integrating with the work on the previous upper and lower sections, to build an integrated depositional model for the entire accumulation in Britannia Field, the Witch Ground Graben and beyond. A complementary field study will be conducted on analogous deposits from the middle Miocene Marnoso Arenacea Formation (central-western Apennines, Central Italy), which consists of slope facies together with a range of gravity-driven deposits (slumps, debris-flow deposits, turbidite packages and massive sandstones). The sedimentology is constrained by a high-resolution bio- and lithostratigraphic framework that permits lateral tracing of individual sedimentary packages downslope, including a large mass-transport deposit, together with subordinate sandy turbidites. Alternative or additional field areas may also be studied. The PhD topic is focused on issues that affect many deep-water hydrocarbon reservoirs, and the insights developed within this project are likely to find much wider application elsewhere.

The studentship is funded by the Leeds Turbidites Research Group (TRG), with support in kind from Britannia Operator Ltd. The student will work in-house closely with BOL geoscientists for part of the project. Activities will include sedimentary and structural logging of cores and the integration of these results with the existing correlation framework for the Britannia Field. In addition, the student will be enrolled in the extensive programme of generic PhD training run within the School of Earth and Environment and will also take selected Masters course modules. Focused training will be given in field methods and wider aspects of sedimentology, as appropriate, both in the field and in the core store. This research and training has a strong industry focus that will provide an ideal preparation for a future career either within the hydrocarbons and marine geotechnical industries or in academic research.
