New Geophysics - confronting fractures!

Advances in seismic technolgy that enable us to become entirely predictive about fractures! 0

Monday, April 27, 2020, London, The Geological Society

We hope that this event will have wide coverage of the rocks, from fractured basement, fractured carbonates to fractured granites and fractured shales. And from folk working in the Middle east, NW Europe, US, Cornwall etc. And from geoscientists, reservoir engineers.....

Our perception is that a lot of very detailed knowledge lies in 'silos' that could maybe be overcome in big companies but is challenging for E&Ps.

So the easy starting point for this event is to enhance knowledge exchange, networking etc.

In particular we look for examples where understanding fractures is key to understanding a field and its reservoirs, and thereby optimising production (and reducing costs by exploiting the fractures rather than being inhibited by them).

Note this event follows our Jan 2018 Fractured Reservoirs event. You can see the full report from the event, including attendee list, by clicking on the cover below

However as an unreconstructed geophysicist I think there is an innovation edge too - how do we get to understand the geometry of fractures, whether they are open or not, away from wells, in the body of the reservoir? I think this is the sort of problem that has been cracked on the Clair field, West of Shetlands, but hasn't been shared!

Note this event follows our Apr 30 2019 "New Geophysical Approaches" event.

David Bamford - Director - Finding Petroleum

Welcome & Introduction

David Bamford is well known around the oil & gas industry both as an explorer and a geophysicist. He holds a Physics degree from the University of Bristol and a Ph.D in Geological Sciences from the University of Birmingham.

Since 2004, he has been a non-executive director at Tullow Oil plc, being recruited for this position especially for his exploration knowledge. He serves on the Nominations and Remuneration Committees, and was chairman of the latter, and Senior Independent Director, for 3 years prior to his retire from the board at the end of April 2014.

He was on the board of Premier Oil from May 2014 to May 2016.

He retired from BP plc in 2003, his last four positions being Chief Geophysicist (1990-1995), Business Unit Leader (General Manager) for first West Africa and then Norway (1995-1999), and finally Head of Exploration until 2003.

He has served on the boards of Paras Ltd, a small exploration and IS/IT consulting company in which he held 22% equity, until its sale to RPS Energy in 2008 and Welltec a/s, a Danish well engineering company, as the nominee of the private equity investor Riverside.

From 2012 to 201 he was on the board of ASX-quoted Australia Oriental Energy as a non-executive director.

He was a founder of Richmond Energy Partners, a small oil & gas research house, and several media companies that focus on the oil & gas sector, and has served as an advisor to Alliance Bernstein, Opus Executive, the Parkmead Group plc, and Kimmeridge Energy LLP. Since retiring from BP, he has undertaken asset and company valuation projects for investment banks, hedge funds and small oil companies.

Kes Heffer - - Reservoir Dynamics

Advances in interpretation of interwell fracture properties from fluctuations in well flowrates

Kes Heffer received an MA in Natural Sciences from the University of Cambridge in 1970 and an MSc in Petroleum Reservoir Engineering from Imperial College, London in 1971. He worked for BP for 29 years, initially in worldwide operations as a petroleum/reservoir engineer, and latterly in research into issues of reservoir description. Since 1999 he has been an Honorary Fellow of the Institute of Petroleum Engineering at Heriot Watt University, Edinburgh, and has conducted research and consultancy work through Reservoir Dynamics Ltd. His current main research interest is the rĂ´le of geomechanics in the processes of fluid flow in reservoirs, and the degree to which these approach a critical point.

Reservoir Dynamics
Reservoir Dynamics Ltd conducts research and provides consultancy services on the topics of geomechanics, faults and fractures and their influence on fluid flow in oil and gas reservoirs.

Conventionally, a dynamic model of a reservoir refers to the simulation of fluid flow within a static framework of rock (apart from a pore volume compressibility that is usually assumed to be homogeneous, isotropic and unchanging). In contrast, plentiful field evidence from worldwide reservoirs indicates that it is not only the fluid that moves during reservoir operations: the rock is also dynamic with small strains which are heterogeneous, anisotropic and focussed on faults, fractures and other discontinuities; this leads to time-varying properties, including permeability. This influence has been seen in production data whether or not the reservoir was characterised as "naturally fractured". Recognition of the involvement of additional physics in reservoir behaviour can lead to benefit for practical issues of well placements, injectivities, productivities, sweep efficiencies, short-term and longer-term forecasting and reservoir simulator history-matching. The technology is well-suited to mature fields, but lessons can be applied to green fields.

Fractures and karst in the carbonate rocks of Florida - origin and interconnectivity

Talk Description.
This talk will focus on the control of groundwater flow (and petroleum potential) exercised by fractured and karstified carbonates in South Florida.

Unlike the petroleum-rich carbonates of the Middle East where relatively little data is actually released (althogh there is extensive fieldwork by groups from the UK), South Florida is typical of US basins and regions in that considerable amounts of data are available on open file or are otherwise.easily accessible.

With respect to the fractured and karstified carbonates of the region, we can say in summary that:

There are three horizons where fracturing and karst have enhanced porosity and permeability

- Paleogene Upper Floridan Aquifer strata
- Paleogene Lower Floridan Aquifer strata
- Cretaceous Sunniland Trend strata

The¨Upper Floridan fracture and karst system is well known.

The Lower Floridan is less well known but borehole and geophysical data suggest fracture networks modified by dissolution.

The Sunniland Trend is poorly known but oil field performance and geophysics suggest fracture flow, possibly enhanced by dissolution.
