Colin Watson

Senior Technical Specialist

Colin graduated from Durham University with a degree in geology and worked for a time as a software engineer before joining GeoScience in 1997 as a geotechnical modeller. He has a love of the great outdoors and enjoys horse riding with his family on and around their farm in the far west of Cornwall.

Experience

May 1994 to Present – GeoScience Limited, Geotechnical Modeller from May 1994 and was subsequently upgraded to Wellbore Rock Mechanics Specialist:

Work carried out on geomechanical and hydrogeological investigations for oil exploration and deep radioactive waste disposal. Main topics include:

  • Borehole Stability Analysis

  • and implementation of geomechanical modelling codes

  • Geomechanical modelling of borehole conditions for derivation of drilling mud weight programmes

  • Database design from handling geomechanical, geological and hydrogeological data.

  • Coupled flow heat transport and solute transport

  • Coupled hydro mechanical processes in fracture network modelling 

Examples of specific work are shown below:

  • Geomechanical modelling of borehole stability for various clients in North Sea, Alaskan, Algerian and Middle Eastern projects

  • Design and development of geomechanics software suite for Borehole Stability Analysis, including quantitative risk assessment procedures

  • Development of FTSA (Fracture Trace Statistical Analysis) code for two plus time dimensional analysis of fracture patterns - EC funded Joule II project

  • Development of numerical minimiser for finite difference borehole solute transport code for interpreting  production log conductivity data

  • Development of NAPSAC fracture network modelling code for equivalent porous medium permeability tensor fitting – AEA Technology

  • Coupled hydro-geomechanical modelling of excavation disturbed zones - NAGRA

  • Authored review of geomechanical modelling techniques - EC funded Joule II project

  • Preliminary coupled thermal-groundwater flow modelling and thermal data collation in support of Nirex 97 Safety Assessment

  • Statistical analysis of hydraulic property field measurements – UK Nirex Ltd

  • Design and implementation of a hydrogeology database – UK Nirex Ltd

 

1987 to 1993 – British Rail/Western Trust & Savings Limited, Computer professional

 

  • Duties included Business, Systems and Technical Analysis; program and database design; implementation and coding. Training included technical and management training

 

1985 to 1987 – Sunderland Polytechnic, Part-time Lecturer

  • Responsible for teaching Engineering Geology to Third Year Combined Science Degree students

 

1983 to 1987 – Consultant

 

  • Part-time Engineering Geology Consultancy in association with Dr R K Taylor for British Gas and French Kier Construction for example. Involving materials testing and interpretation and reporting

 

1982 to 1987 – Durham University

 

  • Demonstrator to Geology and Engineering BSc courses and Engineering Geology MSc course
