Alain Gringarten. Alain Gringarten (born 26 August 1945) is a French scientist, professor, and former Director of the Center for Petroleum Studies at Imperial College London.

Career
Since 1997, Alain Gringarten has been Professor of Petroleum Engineering and Director of the Center for Petroleum Studies at Imperial College, London. He coordinates all research and postgraduate teaching and activities in petroleum-related studies at the College.

Scientific contribution
Alain Gringarten made major contributions in many breakthrough advances in well test interpretation, including: the use of Greens functions; the "Gringarten type curves" for wells with wellbore storage and skin, fractured wells, and wells with double porosity behavior; the first major commercial computer-aided interpretation software; and a well-test interpretation methodology which has become standard in the oil industry. He was also an early pioneer of multidisciplinary studies, both in industry and in academia.

As a result, well-test analysis started becoming more useful as a reservoir-description tool, both during exploration and for reservoir simulation.

In recent years, Alain Gringarten spent a lot of time in research of deconvolution as a well-interpretation tool. He is one of the main contributors in establishing a stable algorithm of deconvolution as a least squares mathematical problem.
