TECHNICAL MEETINGS LONDON London


Erkan Karakaya, of Schlumberger, will present the pre-dinner talk at the SPE London evening meeting, on 29 October, at the Geological Society, Piccadilly.


‘Perceived value and popularity of Decision Analysis tools in Upstream E&P’ will remind the audience of the basics of decision analysis, discuss its application within


the oil and gas industry, and focus on the motivations, design and results of a study to gauge the industry’s perceptions of its value.


Erkan Karakaya is Principal Economist & New Ventures Director at Schlumberger’s Production Management Segment and a recognised Schlumberger domain leader in decision analysis and risk management. Before assuming this role, Erkan worked as General Manager of Planning, Risk & Reserves Business for the Middle East, where he provided planning, economics and corporate risk assessment solutions to regional oil companies, many of them key OPEC producers. Prior to that, he worked for Petronas in various positions, his responsibilities including Upstream asset acquisition and divestment, Upstream portfolio management, corporate strategy development, economics and schedule modelling of Upstream projects, strategic alignment of cross-discipline expertise, risk modelling, and management information systems.


Erkan has an MSc degree in Petroleum Engineering from Middle East Technical University, where he also taught Engineering Mathematics, Petroleum Economics and Reservoir Simulation courses. He also holds an MBA degree from Manchester Business School.


Following the networking buffet, SPE Distinguished Lecturer Martin Rylance, of BP Global Wells, will present ‘Unconventional completions: a paradigm shift’.


The approach to the development of unconventional resources in North America was born out of the marriage of horizontal wells with hydraulic fracturing. While highly successful, it was developed and applied with few options/capabilities available for lower completion design. The end result has been the application of high-rate water-frac/hybrid/gel approaches, over a number of clusters, which attempts to perform multiple fractures at the same time during each treatment execution. Ideally, a fracture initiation occurs at each cluster, though this is rarely achieved, and in this way the overall well length can be treated in a timely and efficient fashion. Additionally, the acceleration of hydraulic fracturing within horizontals has resulted in a schism in fracturing, with the creation of two competing approaches: the open-hole and cased-hole techniques. Both completion approaches are valid and have genuine

application across hydraulic fracturing; however, the industry requires the elusive lower-completion combination of open-hole efficiency combined with cased-hole accuracy.


This presentation argues that a number of relatively recent advances in available lower completion technology will allow the industry to achieve this ‘holy grail’. It will also demonstrate that the application of such new approaches can result in far better efficiency of the fracturing process and a higher success rate, with less environmental impact and improved economics.


“The one idea that I would like members to take away from this lecture is that while brute force and macro-economics can allow the initial delivery of a new resource, it is in fact the engineering and optimisation of these that make such an approach sustainable and economic in the longer term,” the Distinguished Lecturer says.


Martin Rylance is the Senior Advisor and Engineering Team Leader for Fracturing and Stimulation within the BP Global Wells Organisation (GWO). He has been with BP and worked with its partners and JVs for more than 25 years, since graduating BSc (Hons) in Pure Mathematics. During this time his roles have included Interventions Team Leader with BPX in Colombia; Head of Fracturing and Stimulation for BP Worldwide, Chief Engineer with TNK-BP, in Moscow, and Project Manager in a number of frontier areas.


He has numerous papers and publications to his name, is an active SPE member and is also a Fellow of the Institute of Mathematics, in London.
