The University of Cambridge BP Institute was established in 2000 by a generous endowment from BP, which has funded faculty positions, support staff and the Institute Building, in perpetuity. The Institute research focuses on fundamental problems in multiphase flow and is highly interdisciplinary, spanning six University Departments.
A new 2 year post-doctoral research position has been established at the BP Institute to explore the dynamics of fluid driven fracture growth in porous rocks. In particular, the project will focus on the possible inhibition of fracture growth by particulate within the injected fluid. The focus will be on theoretical characterisation and experimental validation of the physical processes governing fluid driven fracturing.

(ii) Modelling optimal mixing processes by variational principles (Dr C Caulfield)
(iii) Experimental and theoretical modelling of particle transport in thin fluid layers (Prof A Woods)
(iv) Modelling hydraulic fracturing processes (Dr J Neufeld and Prof A Woods)
We have developed a technique to encapsulate microbes such as yeast and bacteria. This technique avoids many of the problems of other encapsulation methods; harsh chemicals, high temperatures or long and complex processes. The capsules, called colloidosomes, are manufactured by a simple method of emulsifying an aqueous phase within an oil phase. The aqueous phase contains the microbes and polymer particles, which move to the surface of the water droplets and aggregate to compose the microcapsule shell.
Biomineralisation is the process by which organisms produce inorganic minerals in order to strengthen and protect the organic tissues. Examples include bones, eggshells, coral, marine mollusc shells and teeth.
The production of biomolecules such as sugars and proteins during biomineralisation directs the shape and structure of the organism’s shell. Depending on the structure of the biomolecule, beautiful and complex shapes can be formed from one single crystal.
Carbon Dioxide (CO2) has been injected into aquifers in several locations in the world. In order to predict the movement of CO2 in an aquifer, we need to know the permeability of the porous rocks, which gives a measure of how easy it is to flow.
In this paper, we have investigated the use of seismic data to estimate the permeability of the rock. In a single layer of rock, there are two possible permeability values which can fit the same noisy seismic data. The same analysis can be extended to a multi layered system, e.g. Sleipner in the North Sea.
