Tim Needham is a structural geologist and managing director of Needham Geoscience. He has worked
as a structural geologist in the petroleum industry since 1988. Before forming Needham Geoscience he has worked with:

Rock Deformation Research (RDR)
BP Exploration
Badley Earth Sciences
Robertson Research

His particular interests are fault and fault seal analysis and naturally fractured reservoirs. Tim has conducted structural evaluations in exploration, appraisal and production settings. These studies range from the analysis of reservoir-scale deformation in core or using image logs, structural interpretation on individual fields and prospects to regional basin scale appraisals. Geographically, these studies include areas of the North Sea, Middle East, North America, South America, North and West Africa and SE Asia.

He has been involved in the delivery of training courses in structural geology, fault seal analysis and fractured reservoir description to industry geoscientists worldwide. Tim also contributes to the teaching on the MSc. course in Structural Geology with Geophysics at Leeds University.

Tim gained a BSc in Geology from Imperial College, London in 1981 followed by a PhD from Leeds University in 1984 for research into the deformation processes at active continental margins which he continued with a Postdoctoral Fellowship at Durham University. Before moving into industry Tim also lectured at University of London Goldsmiths’ College. Tim is also involved with Geological Society of London. He acts as an editor for the Journal of the Geological Society and sits on the Petroleum Group committee.

Needham Geoscience are based in the town of Ilkley, West Yorkshire, in the shadow of the famous Ilkley Moor. Communications are good with Leeds Bradford International Airport only about 15 minutes away.
The airport has connections to Heathrow, Amsterdam and Aberdeen allowing a worldwide scope to business.

There are good rail and road links with the nearby city of Leeds and the Yorkshire Dales are only a few minutes in the opposite direction.
