We believe that it is very important to keep up to date with the latest developments in Geological Science, so our staff regularly attend conferences around the world. Here you can find some of the papers that we have presented at these conferences.

Mike Ashton - Fault and fracture prediction from coherence data analysis, a case study - The Magnus Field, UKCS


This paper presents a new approach to fault and fracture interpretation, FaultMagic®, which is based on the analysis of coherence and the integration of borehole data. It allows the interpreter to produce detailed and highly accurate fault and fracture maps using a data-driven approach. Interpreter bias is removed, and the speed and efficiency of mapping greatly increased.

Meriem Bertouche and Mike Ashton - Pore-scale fabric as a tool to distinguish in situ from remobilised mudrocks in deepwater deposits


Traditional core logging cannot always distinguish in situ from remobilised mudrocks due to the absence of diagnostic criteria, particularly from single core. Image logs generally can help to differentiate the origin of mudrocks, but where the scale of deformation/slumping is below tool resolution, it might prove difficult to confidently comment on the nature of mudrock origin.

Matthieu Deville de Periere - Quantitative Characterisation of Microporous Micritic Matrix. Examples from Cretaceous of the Middle East


For this study, samples were collected from three oil-bearing reservoir within two Cretaceous Formations (the Berriasian/Valanginian Habshan Fm. and the Cenomanian/Mid-Turonian Mishrif Fm.) to examine the vertical and lateral discrepancies in their petrophysical parameters. Scanning Electron Microscopy (SEM) was used to investigate two potential controls of reservoir properties: (1) micrite particle morphology (shape and inter-crystal contacts); and (2) micrite crystallometry, defined as the median size of micrite particles measured on SEM photomicrographs. These data are compared with three petrophysical parameters (porosity, permeability and pore threshold radius distribution) and the results reveal that micrite matrixes can be subdivided into three petrophysical classes, each with its own distinctive crystallometry, morphology and reservoir properties.

Matthieu Deville de Periere, Kate Garrick, Meriem Bertouche and Andrea James - Field-Scale Reservoir Quality Variations and Predictability in Uncored Intervals within the Arab Formation, offshore Abu Dhabi (United Arab Emirates)


This field-scale study presents the results of integrated sedimentology and reservoir quality assessment of the Arab Formation Members A to D, offshore Abu Dhabi. The reservoir quality evaluation based on conventional core analyses data, thin-sections and logs highlighted that reservoir potential was initially closely related to facies variations. The distribution of reservoir quality within the limits of the stratigraphic cycles is investigated to understand the impact of the sedimentological and diagenetic influences on reservoir behaviour and distribution.

Michael Fuchs - Reservoir Heterogeneity of the Mishrif Formation, Rumaila Field, Southern Iraq


This paper briefly illustrates how results from a series of sedimentological, diagenesis, chemo/ biostratigraphic studies and an interpretation from a new 3D seismic volume have been used to construct a new sequence stratigraphic framework and highlight lateral heterogeneities.

Kate Garrick - Integrated Core and Log-based Approach to Enhancing the Understanding of Reservoir Distribution within the Arab Formation, Abu Dhabi: Constraining the Future Reservoir Model Build


Correlation and prediction of reservoir quality variability/heterogeneity within shallow carbonate ramp deposits of the Arab Formation in an Abu Dhabi offshore field has previously proved challenging. This study, commissioned by ADMA-OPCO, presents the results of integrated sedimentology and reservoir quality assessment of the A to D members of the Arab Formation.

Kate Garrick, Neil Bishop, Jon Gant, Meriem Bertouche, Andrea James and Matthieu Deville de Periere - Enhancing the Sedimentological Understanding within the Arab Formation (Upper Jurassic), Abu Dhabi - Constraining the Future Reservoir Model Build


Correlation and prediction of facies and reservoir quality variability/heterogeneity within shallow carbonate ramp deposits of the Arab Formation in an Abu Dhabi offshore field has previously proved challenging. This study, focuses on the results of an integrated sedimentology and reservoir quality assessment of the Arab Formation. Specific focus has been placed on detailing depositional architecture, within which variations in reservoir properties have been identified.

Kate Garrick, Matthieu Deville de Periere, Meriem Bertouche and Andrea James - Reservoir Characterisation of the Arab Formation (Upper Jurassic), offshore Abu Dhabi (United Arab Emirates)


Correlation and prediction of reservoir quality variability/heterogeneity within shallow carbonate ramp deposits of the Arab Formation has previously proved challenging. This study presents the results of an integrated reservoir characterisation (including sedimentology, reservoir quality assessment and openhole logs response) of the Arab Formation Members X1 to X4 in a major oil-bearing reservoir located in the offshore Abu Dhabi.

Andrea James - A sedimentological and diagenetic description of the Carboniferous section in RKF Field, Berkine Basin, Algeria


Sedimentological, diagenetic and palynological description of the Carboniferous section (RKF Sands) was carried out on one RKF well. This study allows an improved understanding of the depositional environments and the architecture of the reservoir, along with its quality (diagenetic effects) and age. These data will be important in 3D modelling.

Boris Kostic - An Integrated Approach Towards a Holistic Sedimentological and Pore-Scale Characterisation of Fine-Grained (Shale) Unconventional Reservoirs


This paper illustrates an example of unconventional reservoir characterisation of a fine-grained formation from the North Sea where the specific aims were to establish the depositional framework for recognising sedimentary environments, recommend sample locations to target specific queries within the sedimentological context for petrographical and geochemical analyses, to investigate what porosity types are present and to assess 'brittleness' of the rocks.

Boris Kostic - Depositional Environments, Architecture and Diagenesis of Fahud Field, Oman


Fahud Field is a giant fractured carbonate reservoir in the Sultanate of Oman. It is contained in the Natih Formation, a 450m thick section of Albian to Turonian high porosity, low permeability shallow water carbonates. Deposition occurred over a period of three regionally correlatable third order cycles in environments ranging from source rocks deposited in intrashelf basins, mud-dominated wacke/packstones of slope environments, coarse rudist sand shoals, tidal flats to back-shoal lagoons. On a large scale reservoir architecture is layer-cake and well constrained by some 400 wells. However, a close look at seismic, outcrop analogues and performance indicated the likelihood of significant internal heterogeneity.

Boris Kostic - Integrated Reservoir Characterization in Pursuit of a Heavy Oil Giant in the Arctic


Alaska’s North Slope is a world-class petroleum basin with some of the largest producing fields in North America. What is not widely known is the vast resource of heavy oil in shallow sands overlying these light oil reservoirs. Development of heavy oil in the Arctic represents a significant departure from conventional light oil developments on the North Slope as well as established heavy oil developments elsewhere in the world. To progress this opportunity, BP has initiated an appraisal program focused on the portion of the heavy oil resource within the Lower Ugnu (M-sand) reservoirs.

Boris Kostic - Increase Productive Life and Add to In-Place Oil in Mature Reservoirs with Integrated Studies: Zubair Reservoir in Kuwait


The Zubair reservoir is an Albian siliciclastic reservoir on production for the last six decades. Cumulative production indicates a higher oil recovery factor than expected. An integrated study involving sequence stratigraphy, sedimentology, biostratigraphy, petrophysics and modeling techniques resulted in a better understanding of rock fabric, mineralogical composition, depositional settings and their evolution leading to discovery of more in-place oil and a rejuvenated development plan.
