"During my stay, I am looking forward to collaborating with the department in two of its active research streams: unconventional well testing and microfluidics. I hope that my expertise and experience in pressure transient analysis and reservoir characterisation will be particularly suited to this research.
Unconventional well testing methods are intended to provide the same valuable information as conventional tests whilst minimising any disruption to either the environment or production operations. Injection testing is an example of a test that has minimal environmental impact but its analysis is more complex because typically, the injected fluid (e.g. water or diesel) is different from the reservoir fluid (oil or gas). Harmonic testing involves creating small controlled variations in a well’s flowrate (that don’t interrupt production) whilst monitoring the associated pressure variations. Unlike conventional tests, harmonic test data are well suited to analysis in the frequency domain. I am also interested in the role deconvolution might play in harmonic test analysis.
Microfluidics is a fast growing technology whose application probably started with the development of inkjet printers. The basic components of microfluidics consist of high precision pumps and flowmeter’s (albeit at a minute scale) connected to pre-designed flow paths. Various fluids can be circulated in controlled conditions and, with additional measurements (e.g. pressure and temperature), the result is what is often called a “lab on a chip”. The study of fluid flow in porous media is fundamental to petroleum engineering. Microfluidics includes all the ingredients for such study at the micro-scale in a controlled environment and provides an exciting new avenue of investigation."
