With the recent plunge in oil prices, all petroleum provinces are even more challenged by poor economic returns. And exploration anywhere is seen as offering poor value for money…….

In part this is due to exponentiating costs – as some would assert, the expropriation of cash flow by oil field service companies. This is a topic for “another day”!

In part it is due to the failure of oil & gas companies to grow reserves, whether by:
· Exploration for new fields
· Exploitation of existing discoveries
· Reservoir Management of recently developed fields
· Deployment of IOR/EOR technologies.

And yet we have a multitude, a “wall”, of data that in principle allows us to better describe basins, plays, prospects and discoveries, and to better describe and monitor producing fields, and the individual reservoirs therein.

In addition to massive amounts of public data, we can transform our (subsurface) capabilities by using new data acquisition technologies - some would call them 'disruptive' technologies. Looking back at our Finding Petroleum events in 2014, the key 'disruptions' now on our radars are:

  • Seismic with Nodes - definitely offshore, potentially onshore, condemning cables to history.
  • Non-Seismic methods - finally demonstrating that they can deliver improved petroleum prediction.
  • Fibre Optics - whether down-hole or ploughed into the seabed.

Integrating, analysing, visualising and correctly interpreting all this data, these multi-measurements, goes way beyond the 'lowest common denominator' un-networked desktop applications available today where the world of innovation has been replaced by ‘one size fits all’.

I have always believed that the best insights are found when everybody – for example, geologists, geophysicists, petrophysicists, reservoir engineers, commercial folk – are looking at the same thing, and working on the problem at hand as a team.

New Technologies can transform our sub-surface insights!

Talk Description
The last two or three years have revealed some profound “technical” issues:

Exploration has everywhere been very unsuccessful over the last 2-3 years, both in success rate and in the discovery of “giants”.
· We have reached the ‘end of the road’ with regional towed streamer 3D as our main exploration tool.

“Reservoir Risk” is a key contributor to the failure of Development projects; too much uncertainty is carried beyond Appraisal and FEED into project design and execution.
· New technologies are needed to reduce uncertainties.

Poor understanding of reservoir dynamics has led to unsatisfactory IOR/EOR projects.
· ‘Richer’ surveillance will improve our understanding of reservoir dynamics.

We need some “Disruptive” technologies:

A bit of a generalisation but “disruptive” transformations in our ability to explore, appraise and manage reservoirs are almost always related to step changes in our ability to acquire subsurface data. What did 2014 bring?

Offshore Nodes ‘came of age’: the key change was the demonstration that the operational problems often associated with seabed kit have been solved. Onshore Nodes may be just over the horizon, from a combination of wireless technology and UAVs. Are cables finally for binning?

Non-Seismic Geophysics: not exactly ‘new news’ but Full Tensor Gravimetry (FTG) came into widespread use onshore (and offshore, too).

Fibre Optics: demonstrated real potential for 24/7 downhole seismic, including Permanent Reservoir Monitoring (see also below), Production Monitoring.

And finally one that wasn’t: we need to figure out why Permanent Reservoir Monitoring has been so slow to take off?

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 joined the board of Premier Oil in May 2014.

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.

Geologic rock property normalisation of seismic

Talk Description
• Prime cause of E&P inefficiency is wrong inter-well forecast of poro-perms, largely risk contingent upon knowing geology as causes spatial property change.
• G&G defines geology via well and sequence shape models, then simulates collective variations potentially caused by (some 15 factorial) changes in sedimentation, lithofacies and /or structural geology, compaction, digenesis, fluids etc.
• To significantly enhance E&P success requires processing of seismic into better geologic, then poro-perm, and fluid models.
• Seismic now provides relatively accurate pseudo sonic log, time, velocity, depth data per 12.5m trace, at <12.5m vertical. P & S velocity data can be gathered pre stack. Seismic provides excellent seismic stratigraphic shapes, potentially enabling quantitative interpretation (QI) to better define geology of deposition and burial changes.
• Where inter-well cells compact normally relative to well data, conversion to inter-bedded lithologies and their poro-perms should be low risk. Therefore, normalisation, per seismic volume having similar burial compaction controls, allows equilibration by depth shift, with well based ‘normal’ depth compaction. This allows conversion of seismic to geo and petro information that is risk dependent primarily on quantification of burial depth equilibration shift.
• Expert geo-detectives need to process seismic +/- well data to filter presence / absence of such geo-causes of property change, relative to burial-change ‘norm’ then generate a normalised, single most probable geo-petro model. QI filters cellular data to quantify separate and net effects of causes of burial changes. Then, cellular seismic numbers = cellular geologic numbers of deposition and burial changes = cellular petro-physical numbers, in one, most probable, multidisciplinary integration, containing presence / absence of geo-risks.
• Integrating, analysing, visualising and correctly interpreting extra multi-disciplinary measurements goes beyond desktop applications available today. So, we beta tested, in > 30 data sets each >600km3, ‘apps’ to process cellular evidence crucial for geo-detection, for current workstations.
GeoDirk found the common denominator between seismic, geology, poro-perms & fluids. Plus or minus we
