Andrew Green - Integrated Geochemical Interpretation Limited IGI Ltd

Andrew Green

Petroleum Geochemist & Modeller

On joining IGI Ltd. in October 2010 as a petroleum geochemist and basin modeller, Andrew's work involves:

• The characterisation of hydrocarbons and petroleum source rocks
  

• The assessment of source generation phase, expulsion timing, and volumetric potential
  

• The prediction of petroleum migration and accumulation patterns spatially
  

through the evaluation of geochemical data and the simulation of petroleum systems utilising a host of industry-standard modelling packages.

En-route to IGI Ltd. Andrew has completed qualifications in Geology, BSc. (Durham University); Integrated Petroleum Geoscience, MSc. (University of Aberdeen) and Petroleum Geochemistry, MSc. (Newcastle University), with 18 months spent working for Shell, UK, between master courses. While with Shell, Andrew was recruited to the newly formed Shell-Schlumberger secondment program, which consequently saw him cross trained as a field wireline logging engineer and deployed to Fahud, Oman.

To date Andrew's academic studies and exploits have been focused on three main areas of geoscience:

• Sedimentology: Concentrating on Triassic and Jurassic sediments Andrew has experience working on the     Southern UK, Wessex  basin, both in respect to mapping the extent of its onshore Dorset Coast exposures and considering both the onshore and offshore in terms of its efficiency as a petroleum system.  He has also evaluated Triassic sequences on the Western Platform, Central North Sea, with regards its potential as a viable petroleum play system.
  

• Geopressure: Conducting an industry wide study into the occurrence and influence hydrodynamic flow has on emplaced hydrocarbons, Andrew focused on compaction driven flow as a mechanism for sub-basinal hydrodynamic aquifer flow. Using database techniques he was able to present not only specific case studies but also characteristic traits related to compaction driven hydrodynamic flow. In addition during his most recent MSc, combining raw wireline data, existent relationships between porosity and effective stress and interpretative knowledge of geopressures, Andrew worked on the prediction of pore pressures within Rossetta Province, western offshore Nile Detla mudstones, along with interpreting the resultant implications for the gas rich petroleum system.
  

• Geochemistry: Looking further afield Andrew has worked on evaluating source rock quality and potential within South Australia, as part of a collective study critiquing hydrocarbon potential in the Copper-Eromanga Basin.
  

In conjunction with IGI company evaluative and database projects Andrew also maintains an active interest in the appraisal of source material and geochemical parameters through the appliance of quantitative petrophysical approaches.

Outside of work I am an active person participating in numerous outdoor pursuits and adventurous expeditions ranging from walking and cycling to mountaineering. These are also complimented by my running and swimming which are combined into my enthusiasm for competing in triathlon events when the weather is warm enough. Other interests also include a love for cookery, growing my own fruit & veg, home brewing and photography.
