Operations Geology Conference: "The Life-cycle of a well"

26-27 November 2014, The Geological Society London  

Following the highly successful Operations Geology Workshop held in Aberdeen in October 2012, the Petroleum Group of the Geological Society are pleased to announce the dates for the next event, which will be held over two days in 2014. Operations Geologists play key integrating roles at all stages of the life cycle of a well. This conference looked at the life cycle of a well and the contributions of Operations Geology at each stage:
  • Well Planning - hazard identification (due to rocks, fabric, pressure, stress, geometry etc) andavoidance/mitigation, targeted data acquisition for all disciplines for life of field
  • Execution - real-time techniques, managing the drilling window, the acquisition and use ofIntegrity test data, appropriate isolation of permeable zones in the overburden
  • After Action Review - NPT analysis and the learning loop, continuous improvement
  • Emerging Technologies - the next generation of needs and solutions – logging, formation andgas detection/analysis, real-time well bore stability analysis tools, PPFG tools

Small to Subseismic Scale Reservoir Deformation

29-30 October 2014, The Geological Society London 

Small to subseismic deformation features can negatively impact reservoir performance and/or be stimulated to enhance field recovery. In many cases such features are controlled by, or interact with, similarly scaled sedimentological features, complicating conventional views of intra-reservoir connectivity and flow unit definition. Whilst the intra-reservoir distribution of these small-scale features has traditionally been ‘modelled’ in the subsurface by applying data from analogue outcrop studies, the recent advances in the acquisition and processing of both seismic and imaging techniques, such as helical CTscans, have provided greater resolution of the ‘subsurface’ than ever before.

This 2-day international conference brought academic and industry geoscientists and engineers together, to examine: (i) how much extra geological detail modern seismic and imaging techniques are now able to provide; (ii) how that expansion of detailed information is being approached and captured by interpreters - and tied back to real reservoir geology; (iii) what ‘new questions’ are now being asked of outcrop and well based studies in order to address the ‘unseen challenges’ of subseismic deformation; (iv) how this is influencing the level of detail that should be captured to define better subsurface flow characteristics within flow simulation models; and (v) how depletion and injection impact upon formation and reactivation of reservoir scale deformation features.

Geometry and Growth of Normal Faults

23-25 June 2014, The Geological Society London 

The past few decades have seen major advances in our understanding of many aspects of the kinematics of normal fault systems. The analysis of high quality 3D seismic datasets of faulted volumes and detailed outcrop studies, combined with complementary geomechanical modelling, have provided much improved constraints on both the nature and growth of faults and associated fault zones. Recent research progress has benefited from the importance of faulting in a variety of application areas, such as the groundwater, minerals and petroleum industries. In a conference convened on the 25th anniversary of the Geological Society’s 1989 ‘Geometry of Normal Faults’ conference, it is intended that the full range of technical issues associated with the growth of normal faults, together with their practical applications, will be covered. The conference is in memory of Juan Watterson, one of the pre-eminent scientists in the field of 3-D fault analysis and modelling.
•3D geometry and kinematics of normal faults
•Internal structure and growth of fault zones
•Deformation within the volume surrounding normal faults
•Fault growth on earthquake through to geological time scales
•Links between the ductile and brittle expression of faults
•Stress- and strain-based methods for analyzing normal fault systems
•Numerical modelling of the geometry and growth of normal fault systems

•Practical application of fault analysis techniques

Reservoir Quality of Clastic and Carbonate Rocks: Analysis, Modelling and Prediction  

29-30 May 2014, The Geological Society London 

Porosity and permeability exert a fundamental control on the economic feasibility of a petroleum accumulation and need to be quantified from basin access to mature production. Quantitatively reporting the mineralogy and pore space characteristics of reservoir rocks is vital in establishing the controls on reservoir quality. Only by doing so it is possible to build predictive capability, essential to successful geological modelling and cross-disciplinary integration. This issue is becoming ever more critical with exploration and production of petroleum in increasingly challenging conditions and from less conventional reservoirs.
Despite the importance to the industry of understanding the controls on porosity and permeability of reservoirs, fundamental issues lack consensus. Reservoir quality is controlled by interdependent sedimentary and diagenetic factors, including sediment provenance and weathering, depositional environment and climate, compaction, recrystallisation and dissolution, authigenic mineral growth, petroleum charge and structural deformation.
This conference seeked to address the factors and processes controlling rock properties of clastic and carbonate rocks as well as showcase novel analytical techniques and demonstrate diagenetic modelling capability. Delegates from both academic institutions and industry are encouraged to attend and contribute in order to represent the range of current reservoir quality research.
  • Provenance and environment of deposition
  • RQ in the sequence stratigraphic framework
  • Clay mineral diagenesis in clastic andcarbonate rocks
  • Quartz diagenesis in clastic rocks
  • Carbonate diagenesis in clastic rocks
  • Near surface diagenesis as a controlon reservoir quality in carbonate systems
  • Porosity modification in the burial realm
  • Fluid-rock interactions
  • Petrophysical RQ characterisation and upscaling
  • Application of RQ analysis for petroleumexploration and production
  • Porosity upsides –predicting anomalously good reservoirs
  • RQ of unconventional reservoirs
  • Computer modelling of diagenesis
  • Experimental approaches to understanding RQ
  • Analytical techniques
  • Geomechanical and structural controls
  • Using RQ to improve rock physics models

Petroleum Geoscience of the West Africa Margin

31 March – 2 April 2014, The Geological Society London 

Petroleum Exploration along the West African margin has a long history. Discovery of commercial oil in the Niger Delta in 1956 and offshore Angola in 1966 led to these two countries becoming the largest oil producers in the region today, accounting for 5% of global daily oil production. Even with this extensive history, however, new exploration plays continue to be found with imaginative ideas & innovative technology.
In the last decade, independent oil companies have aggressively pursued new concepts – from stratigraphic traps in Ghana to recent exploration success in Cameroon & Equatorial Guinea. Independents and Majors now compete head-to-head in the more “mature” areas such as Gabon & Angola, investing in new play concepts and exploring the pre-salt, prompted by successes on the conjugate Brazilian margin. To the south, Namibia is undergoing renewed exploration activity. In short - it’s an exciting time to be exploring in West Africa.
This conference showcased the regional geology, from Morocco to South Africa, sharing insights on recent exploration successes and emerging plays, & integrating inputs from academia, industry, and national oil companies.

Reducing Subsurface Uncertainty & Risk Through Field - based Studies: The Value of Outcrops and Analogues in Hydrocarbon Exploration, Development and Production Implications for Global Exploration and Production

4-6 March 2014, The Geological Society London 

This meeting provided a timely revisit and reappraisal of the value and impact of outcrop based fieldwork in hydrocarbon exploration, appraisal, development and production. In recent years we have seen a refreshed focus on frontier exploration, in increasingly difficult settings, and the challenges of new developments such as deepwater clastics and carbonates. This has led to the resurgence in the appreciation, use and need for outcrop based studies as analogues and benchmarks for the subsurface. This applies both to the overburden and the reservoirs. Digital technologies such as remote sensing and digital data capture have revolutionised field-studies, however traditional methods (e.g. mapping, logging and sampling) remain at the very core of any field study.
This meeting offered an exciting opportunity for key researchers and users of these datasets to come together, learn from recent advances and look forward to future directions and needs. A key objective is to engage industry groups and academia in a dialogue and knowledge sharing that reflects the current status and future potential of this important area.
• Exploration: Reconnaissance-scale fieldwork
• Structural Analogues - regional to reservoir scale
• Applications to Reservoir and Field Appraisal, Development and Production: Outcrop-scale fieldwork
o Clastics
o Carbonates
• Unconventional Hydrocarbon Resources
• Health, Safety & the Environment and field studies

• Looking to the future
