Petroleum Geology of the Black Sea

6-7 October 2015, The Geological Society London 

The Black Sea retains an abiding fascination for petroleum geologists. Large structures, seepage, widespread sources rocks, and producing fields around its margins invite serious consideration of its exploration potential notwithstanding the challenges of drilling in deep water. There has been renewed exploration activity in recent years and some notable exploration success as well as disappointments. This conference  reviewed recent and upcoming exploration activity alongside key geological issues for understanding subsurface risk in the basin including but not limited to:
  • Geodynamic Evolution
  • Biogenic gas plays
  • Pre-rift plays including carbonate build-ups 
  • The importance of outcrop studies from
  • Syn-rift play potential the margins of the basin
  • Source rock distribution and maturity 
  • The importance of regional seismic data
  • Sediment provenance studies and impact on reservoir quality

Sedimentology of Paralic Reservoirs: Recent Advances and their Applications

18-19 May 2015, The Geological Society London 

Paralic reservoirs record clastic deposition at or close to sea-level. They reflect a range of depositional environments including deltas, shoreline-shelf systems and estuaries and have provided the backbone of production in many mature basins around the world, currently contributing around 30% of global conventional hydrocarbon production. Strata that host these reservoirs are shaped by a wide variety of depositional processes and controls that reflect the upstream supply of sediment and water, the characteristics of the receiving basin, relative sea-level and tectonic setting. Consequently they exhibit much variability in their stratigraphic architecture and sedimentological heterogeneity, which translates into complex reservoir performances that are challenging to predict. However, new research themes have emerged in recent years: contrasts between regressive and transgressive coastlines; along-strike and cross-shelf variability; shoreline trajectory concepts and the impact of autogenic responses during constant forcing. This conference addressed these new themes together with developments in established approaches to discuss the current state of knowledge in the exploration and production of paralic reservoirs.
Themes:
  • Modern studies, numerical & experimental modelling of paralic systems
  • Paralic reservoir character & behaviour: imaging, sedimentology, ichnology, architecture & reservoir models
  • Classification & role of mixed energies in strike & dip growth of paralic systems
  • Tide-generated heterogeneity in paralic reservoirs
  • Paralic muds & mudstone reservoirs

Recognising the Limits of Reservoir Modelling - and how to overcome them

4-5 March 2015, Elphinstone Hall, University of Aberdeen

Nearly 20 years ago a paper describing some then best-practice reservoir modelling included this statement in the concluding section: “The parameters that we used to fine-tune this match were the well connection factors, the well skin factors and the relative permeability curves”. Can we honestly claim to have made progress from that situation? Geoscientists and petrophysicists labour hard at reservoir characterisation. We are seduced by precision and enticed by the sophistication now offered by software. Meanwhile, we have become habituated to permeability multipliers, pore-volume multipliers, adjustments to the relative permeability curves and to modifying fault properties (up to and including their existence), and use the resulting models to support major capital investment decisions.
So what have we actually learned in the 20 years since geocellular modelling arrived on our desktops? Can we turn all that hindsight around into useful foresight? In situations where we cannot learn from the history-match, what can we learn from history? What are the most frequent failings of our geomodels?
Now that geomodelling is a mainstream activity, our attention moves to finding effective approaches to support investment decisions; multi-scenario, multi-scale modelling with multi-phase upscaling represents an ideal but requires smart and nimble application to be practical and efficient.
This conference seeked warts-and-all tales of reservoir models that eventually became accurate; descriptions of iteration between reservoir characterisation and reservoir performance; stories of managing small-scale heterogeneity in large scale models. The conference seeks to recognise the limits of our current workflows and chart a way forward to more accurate, useful and efficient reservoir modelling practices.
Contributions are invited on current reservoir modelling cases and techniques, dealing with:
  • Handling incomplete or imperfect data – modelling data or concepts?
  • Reconciling and integrating multi-scale data in models – dealing with gaps
  • Multi-scale modelling – rather than single detailed models
  • Impact of heterogeneity on fluid flow behaviour – what matters to flow?
  • Conditioning to production data in mature fields – how to iterate effectively
  • Advanced gridding and simulation techniques – breakthrough technologies
  • Linking reservoir models to commercial decisions – adding value through modelling
