About GeoPressure Technology
GeoPressure Technology Limited was
founded in 1997 and has grown to offer training and consultancy
in pressure problems, as
well as a suite of niche software designed to manage and
visualise pressure data.
The company has developed alliances with several
leading companies to strengthen its links with data providers
and its ability to provide superior software.
GeoPressure Technology is located in the University
of Durham Science Park in the historic city of Durham, North
East England. It maintains links with research groups of Durham
University focused on challenges relating to fluid pressures
in the subsurface.
In 2006, GeoPressure Technology became an Ikon Science company

Dr Richard Swarbrick, Managing Director
Before founding GeoPressure Technology, Dr Richard Swarbrick
completed a PhD in sedimentology/tectonics at Cambridge University, and subsequently worked as a geologist for Mobil for ten years from 1979. During
that time he worked in exploration and production assignments
in both the UK and USA.
In 1989 he began teaching petroleum geology and related courses
at the University of Durham where he continues to be involved in research and teaching.
Between 1994 and 2001, Dr Richard Swarbrick was also the principal
investigator of GeoPOP (GEOsciences Project into OverPressure),
a multi-disciplinary research group funded by 16 oil/gas companies.
Richard has taught courses in many of oil centres around the world, either as open courses or in-house training companies. He consults widely and continues to present conference papers and publish articles relating to sub-surface pressures.
Dr Richard Lahann, Geologist Associate
Dr. Richard Lahann is an independent consultant with a long-term relationship with GeoPressure Technology. After completing a Ph.D. in low-temperature geochemistry at the University of Illinois in 1975, Richard joined the Department of Geology faculty at SUNY-Binghamton (Binghamton, New York). In 1980, he joined the Exploration Research Division of Conoco.
In September of 2003, Richard left ConocoPhillips after 23 years of service. His contributions during that time included technology development and application in clastic diagenesis/reservoir properties and fluid/fracture pressure causes, prediction and interpretation. From 1996 to 2003, Richard was responsible for fluid and fracture pressure prediction and drilling support for many international wildcat wells. His experiences range from well-site activities to theoretical shale petrology issues.
Richard has maintained an active publishing record in clay mineralogy and clastic diagenesis and has been an officer of the Clay Minerals Society. He continues to publish on the relationships between shale petrologic changes and fluid pressure generation.
Stephen A O'Connor, Senior Geologist
Stephen is a petroleum geologist with Masters degrees in Sedimentology and IT/Geomodeling. He has worked with many types of oilfield data, particularly in the areas of reservoir quality and structural geology.
He started his career working on exploration assignments for Unocal and BP/Amoco before moving to service companies to work in sedimentology/diagenesis in areas such as UKCS including Atlantic Margin and the Middle East
Lately he has become involved in fault seal analysis of UKCS reservoirs (Norwegian continental shelf, Inner and Outer Moray Firth, Southern Gas Basin), Gulf of Mexico, South China Sea and East Africa as well as geomodelling and overpressure analysis.
Dr Phillip Clegg, Senior Geologist
Phillip completed his BSc. (Hons) in geology at Durham University in 1998 which was followed by a PhD in structural geology, studying the complex kinematic history of transpression zones. During his PhD studies he had a temporary post as a technical assistant with the GeoPOP (GEOsciences Project into OverPressure) research team.
Following the successful completion of his PhD he was appointed as a Post-Doctoral Research Associate within the Reactivation Research Group (RRG) at Durham University where he was involved with the development and application of digital mapping, laser scanning & use of GIS & 3D visualization methodologies in structural geology, which ultimately led to the creation of GAVA (Geospatial Acquisition, Visualization & Analysis). The GAVA methodology is being further developed by RRG as a means of creating ‘virtual’ structural models for the petroleum exploration industry.
David T Scott, Geologist
Graduating from Durham University in 2002 with a BSc. (Hons) in Geology, David was introduced to the oil industry in his final year by participating in a Shell Technology Enterprise Programme. Upon successful completion of the project the host company, HRH Geological Services Limited, offered him permanent position in Aberdeen, working both offshore as a Mudlogger/Geologger and ultimately wellsite geologist and onshore in the business development and client contact processes.
David joined Geopressure Technology Limited in June 2007 and has since been involved in both the regional pressure study for the North Viking Graben and a number of individual client well planning projects. He is currently studying for a Masters Degree in Petroleum Engineering at Heriot-Watt University.
Alan J White, Software Developer
Alan is a graduate electrical engineer, but most of his career has been
devoted to software development.
For many years, he worked for the British Gas pipeline integrity
centre based at Cramlington, Northumberland,
and was heavily involved in developing their data analysis software.
In 1991 he left to do freelance software
project work. In February 2004, he started working for GeoPressure Technology on the development of PressureView 3.0 and PressureView Express.
Dr Patricia Kelly, Data Analyst
Patricia has a background in analytical chemistry. Her PhD from Newcastle University concerned the standardisation of calcium measurement in clinical chemistry. She continued with post doctoral research both at Newcastle and Durham Universities. In 2004 she gained a CHE in Information Technology from Durham University by part-time study.
Patricia has worked at GeoPressure Technology since 2002. She manages the company’s pressure database.
Chris Hogg, Financial Controller
From 1997 - 2001 Chris worked for Dr Swarbrick on the GeoPOP project, maintaining the research budget as well as organising travel and producing the six-monthly reports. Since then Chris has worked for GeoPressure Technology as secretary/financial controller on a part-time basis.
