Tristan S Reilly
Tristan Reilly works for IHS Markit, a large multinational organisation focusing on data analytics, consulting, forecasting and insight for a wide range of industries. Tristan's role as a Senior Research Analyst in the Energy and Natural Resources division of IHS Markit concentrates on Oil & Gas fields and prospects located in the Middle East and South Asia. Primarily, he works with other researchers and analysts to deliver critical upstream oil and gas exploration and production data and expertise to aid in geological, petroleum engineering, and Oil & Gas financial studies.
Tristan is responsible for processing and analysing data from the Middle East, as well as Pakistan and Afghanistan. He has considerable prior experience with India, Bangladesh and Sri Lanka. Additionally, Tristan researches and authors papers on existing and emerging exploration and production technologies published in petroleum industry/geoscience journals.
Tristan obtained his BSc in Geological Sciences and an MSc in Structural Geology and Geophysics, from the University of Leeds, United Kingdom. He is also a member of the Society of Petroleum Engineers (SPE) and the Petroleum Exploration Society of Great Britain (PESGB).
Prior to working at IHS Markit, Tristan has undertaken field mapping and seismic interpretation studies whilst at university and has also worked on major civil infrastructure projects in remote and urban areas of Australia.
Supervisors: Dr. Sarah Haggas - Director, Middle East

In January 2017, Iran passed a new law stating that flaring would be reduced to less than 10% of 2016 levels by the end of 2021. The law makes it easier for private investment in the oil and gas sector to reduce flaring, and comes after the US lead nuclear sanctions began to be phased out in mid-2015 which can be reintroduced if Iran violates the accord. One such area in which Iran has sought to reduce flaring has been from the offshore South Pars ‘Supergiant’ gas field in the Gulf (Figure 1). Flaring has reduced at the field over the past decade, but Iran now seeks to decrease it even further and to harness a greater amount of the field’s vast reserves for domestic consumption and potential export. Qatar, on the other side of the Gulf, has had much success in attracting international investment to develop its substantial gas resources at North Field, and is reaping the rewards of two decades of major LNG exports; can South Pars emulate this?
In recent years there has been a greater impetus on domestic conventional gas resource identification and extraction with the government attempting to reduce the amount of regulations on the petroleum industry and boost investment. Longer term, one area which has been identified as a potential way of increasing production is by unlocking gas hydrates from under the ocean floor. India is estimated to have as much as 66,900 Tcfg located in India’s deep water regions (AK Jha, SPE, 2012). This volume is 420 times the estimated 157 Tcfg of India’s in place conventional gas (IHS Markit, 2016). Despite these extraordinary volumes and with gas hydrates being a relatively clean fossil fuel, the technology to produce gas hydrate remains at the theoretical and testing stages. This article will look at gas hydrates located in deep marine conditions; how they are formed, how they are imaged and how they could potentially be extracted. The other main type of location in which gas hydrate is found is in extremely low temperature conditions, predominantly inside the permafrost of the Arctic Circle, and is outside the scope of this article.
Two of the basins where EOR has been applied are the Cambay and Barmer Basins, located in the states of Gujarat and Rajasthan respectively. The basins were formed due to continental rifting during the Late Cretaceous associated with the break-up of the super continent Gondwana. The rifting created two elongated NNW-SSE depressions which have been filled with fluvial and marine deposits resulting in the source, seal and reservoir rocks which are present today. Important trapping mechanisms include rift related structural traps as well as stratigraphic pinch outs.
Despite similar evolutions for both basins, there has been a marked difference in the exploration of the two. The Cambay Basin has entered into a mature stage after extensive exploration and production over the past 70 years and still accounts for ~13% of India’s yearly oil production. Conversely, the Barmer Basin was unattractive for exploration until 1999, when new seismic surveying and processing techniques were applied. A total of 37 discoveries have been made since then and the basin now accounts for ~23% of India’s yearly oil production.
This paper looks into the impact of two EOR techniques: In-Situ Combustion (ISC) and Chemical Flooding, in the Cambay and Barmer Basins respectively. The production gain from these techniques, combined with cost reduction through improved efficiencies, could help to promote the techniques to other fields in the country.
Thesis Chapters by Tristan S Reilly
Using seismic and aeromagnetic data, deformation within the north-western portion of the Bushveld was mapped and classified based on previous studies. It becomes apparent that without mine data and abundant borehole data, seismic and aeromagnetic surveys are limited in their scope of investigation. An entire survey consisting of all available data is required for the accurate interpretation of the internal stratigraphy of the Bushveld Igneous Complex.
