Event description

Description

Join the PESGB Ireland regional branch and Young Professionals for an evening seminar to learn about the complexities and recent learnings from distal domains in contental break-up, the influence of these factors on pre-drill risk, and insights into the future of these exciting exploration frontiers.

The talk will be followed by networking and refreshments in Slattery's pub.

Abstract:

Recent discoveries in the distal domains of the Atlantic margins have challenged existing geological models and with it conventional wisdom. The discoveries highlight the complexities involved in the final stages of breakup of the Atlantic Ocean. In particular, that heat flux can significantly vary through time and be high enough to mature organic matter on hyperextended continental and oceanic crust in the absence of significant burial.

The insight has resulted in significant acreage capture in the distal domains of the Atlantic margins. Extrapolation from our proven plays into frontier plays in the distal domain is not straightforward and careful consideration needs to be given to the age of rifting, volume of magma, sources and extent of heat flux and the predicted source and reservoir facies within the distal domain. Hydrocarbon phase, CO2 prediction and the potential for cementation of reservoirs by hydrothermal fluids are all key pre-drill risks.

Should the industry get this right the future of frontier exploration in the Atlantic looks bright.

Speaker Bio:

Dr. Helen Doran obtained her PhD from the University of Edinburgh. Since joining the energy industry 15 years ago, she has explored many of the worlds most proflic continental margins, first with BP and more recently with Ophir Energy. Over the years her search for new plays to explore has shifted from the known and reasonably well-understoned proximal domains into the unkown and very poorly understood distal domains. Her recent work and interests focuses on understanding heat flow and subsidence around passive margins, how it changes from the proximal into the distal domains and how this change impacts our perception of plays. Helen is currently Principal Geologist for Ola Geoscience and provides consultancy service in play based exploration with a focus on heat flow prediction. In addition to her consultancy work she is the current technical chair of the PESGB Africa, and a Research Geoscientist for Westwood Energy.
