Sediment compaction underpins basin modelling and pre-drill pore pressure prediction. Clay compaction is complex in that both mechanical and chemical compaction are driven by mineralogy, grain size, pore fluid chemistry, temperature, stress, rates of burial and possible exhumation. In a comprehensive study, Cicchino et al. systematically examine possible reasons for a regional variation in porosity by a factor of two in Cretaceous mudstones below 2700 m depth, offshore Norway. By integrating seismic data, well-logs, cuttings analyses, pressure measurements and temperature profiles the authors conclude that the porosity variation is caused by regional variations, over the past 3 Ma, in the ability of porewater to escape from mechanically compact mudstones undergoing chemical compaction and lithification. Since chemical compaction is arrested if porewater cannot escape, porosity is retained with a minor increase in pore pressure. This significant paper offers new insights into regional porosity variations and cautions against relying uniquely on porosity retention as a pore-pressure indicator.

For their paper 'Interaction of stratigraphic and sedimentological heterogeneities with flow in carbonate ramp reservoirs: impact of fluid properties and production strategy', published in Petroleum Geoscience, volume 20, issue 1, February 2014, pp. 7-24.
The authors develop a suite of static models that capture the range of plausible stratigraphic architectures and rock and fluid properties associated with carbonate ramps. They then use these models with experimental design techniques to explore, by flow simulation, the influence of stratigraphic and sedimentary heterogeneities, well placement and completion strategies, fluid properties, and rock types on flow during water-flooding in each model. In their simulations, the modelled geology was found to be more important than the fluid properties or the specific production scenario. Rock properties affected original oil in place more than recovery factor, and reservoir architecture exerted primary controls on recovery regardless of production strategy, although well spacing impacted sensitivity to factors controlling vertical flow. This excellent academic analysis brings insights that will assist both flow simulation and production strategy in real-world field developments.

For their paper 'Geologically-based permeability anisotropy estimates for tidally-influenced reservoirs using quantitative shale data', published in Petroleum Geoscience, volume 19, issue 1, February 2013, pp. 3-20.
Burton & Wood present a well-researched, argued and illustrated description of a workflow to relate permeability anisotropy at the reservoir scale to shale geometry, shale fraction and the vertical frequency of shale beds. Using data from well logs, cores and lidar scans at outcrops in Canada, New Mexico and Utah, they show how the unique shale character of each unit results in a different distribution of permeability anisotropy according to whether the geological environment is an estuarine point bar, a tidal sand ridge, or a tidal bar. Shales have been known to act as flow baffles for decades but this type of application has previously been limited by the lack of published shale-body distributions in tidally influenced reservoirs. The workflow presented here has wide-reaching application in other similar depositional environments.

For their paper entitled ‘Overview of the Palaeozoic-Neogene evolution of Neotethys in the Eastern Mediterranean region (southern Turkey, Cyprus, Syria)’, published in Petroleum Geoscience, volume 18, issue 4, November 2012, pp. 381–404.
This paper presents an integrated synthesis of the geological and tectonic development of the easternmost Mediterranean basin from late Palaeozoic to Mid-Miocene times. The results of fieldwork in remote onshore locations, in collaboration with local research and knowledge, are combined with recently published studies to produce a series of regional palaeogeographic and palaeotectonic reconstructions. These highlight the timings of basin development and ocean closure, along with associated ophiolite emplacement, which the authors use to support an alternative model for the timing and tectonics of the Eastern Mediterranean basin. This detailed synthesis provides an excellent source reference for

For their paper entitled ‘Quartz cementation in mudstones: sheet-like quartz cement from clay mineral reactions during burial’, published in Petroleum Geoscience, volume 17, no. 1, February 2011, pp. 53–63.
This paper presents new findings resulting from detailed and high-resolution petrographic examination of deeply buried mudstones from the Vøring Basin, offshore Norway. The authors demonstrate that authigenic, sheet-like or platelet-shaped quartz cement parallel to bedding is developed as a result of clay mineral transformations during burial and compaction. These cements may act as mudrock stiffening agents and vertical permeability barriers and as such may contribute to shale anisotropy and overpressure development. These innovative observations may significantly affect our understanding of shale diagenesis, with the potential for wider implications in hydrocarbon exploration.

For their paper entitled “Geodynamics of the central South Atlantic conjugate margins: implications for hydrocarbon potential", published in Petroleum Geoscience, Vol. 16, nr 3, pp. 217-229.
This geographically wide-ranging and excellent multi-disciplinary contribution examines rifting and complex extension behaviour in the South Atlantic area and presents a new model for restoration of this province. The study presents an innovative approach to the synthesis of gravity and magnetic data with regional seismic interpretation and mapping; this, coupled with facies modelling and palaeoclimatology studies, has allowed the geological history of the margin to be explored. Inherited basement structural trends appear to partition crustal strain, such that both pure shear and simple shear end-member mechanisms are recorded by the syn-rift subsidence patterns. The implications for source and reservoir rock distribution and hydrocarbon exploration potential have been addressed in the light of the results.

Effects of depositional and diagenetic characterstics on carbonate reservoir quality: a case study from the South Pars gas field in the Persian Gulf Petroleum Geoscience vol.15, nr4, pp 325-344
A comprehensive and detailed geological study of the Persian Gulf's Permo-Triassic Upper Dalan-Kangan carbonate-evaporite interval, which hosts the largest reserve of non-associated gas in the world. The authors undertake a comprehensive and detailed facies analysis in the South Pars Field to establish within individual units the original depositional fabric and geometry, which is inherited from position within a homoclinal carbonate depositional ramp. While this forms the basis for rock typing, superimposed on this depositional fabric is a variable diagenetic imprint, resulting from differential burial and exposure.
An excellent study, and a very well written paper, recording the very detailed petrographic and supporting work on an important heterogenous carbonate reservoir in a relatively unpublished area.

For their paper "Integrated geological and geophysical analysis by hierarchical classification: combining seismic stratigraphy and AVO attributes", published in Petroleum Geoscience Vol.14.
The authors demonstrate the value of an innovative method combining seismic geomorphology, seismic stratigraphy, and fluid response from AVO, calibrated with existing geological and hydrocarbon data. Their method enables the identification of exploration leads in a consistent manner, reconciling the geological framework with seismic texture attributes and with AVO attributes for hydrocarbon mapping. The integrated workflow facilitates final interpretation of the sequence stratigraphic framework, depositional environment and ranking of the best prospects.

For their paper "Static characterisations of reservoirs: refining the concepts of connectivity", published in Petroleum Geoscience, Vol.13 No. 3.
This landmark paper illustrates the interaction between static 3d reservoir models and their dynamic fluid flow simulation, with particular emphasis on permeability variation and the concepts of connectivity and continuity. Key factors controlling reservoir connectivity are addressed, and new techniques are introduced to allow detailed characterisation of spatial variation of permeability within the reservoir. These innovative concepts integrate into the simulation model, and have associated implications for sweep efficiency and reservoir performance.

For their paper "The Structural Geology of the High Central Zagros revisited (Iran)", published in Petroleum Geoscience, Vol. 11 No.3. This is a multi-disciplinary study in classically thorough exploration style that examines the complex structure, geology and petroleum potential of this under explored area. Surface geological mapping is integrated with the limited well and seismic data available and is combined with recent satellite data, aeromagnetic, gravimetric and magnetotelluric data to generate useful petroleum play concepts. The work is of a particularly high standard and represents a valuable pioneering step in assessing the petroleum possibilities in this challenging area. Totally aside from its excellence as an achievement, the work is also a tribute to Norman Falcon for whom the Zagros Mountains region had claimed the biggest share of his geological activity and technical focus.

For their paper “A Strategy for Modelling the Diagenetic Evolution of Seismic Properties in Sandstones”, published in Petroleum Geoscience, Vol. 12, No. 4.
The authors have presented innovative ways of incorporating geological and geochemical processes and implementing mineralogical reactions in rock physics modeling. The approach consists of a new interdisciplinary workflow: advanced geological modeling of mineralogy and porosity evaluation, followed by rock physics modeling of seismic properties that have been affected by diagenesis.
The strategy presented can be treated as a new tool for exploration purposes, particularly for subsurface saturation, lithology and porosity prediction.

For their paper: “Modelling of hydraulic leakage by pressure and stress simulations and implications for Biot’s constant: an example from the Halten Terrace, offshore Mid-Norway”, published in Petroleum Geoscience Vol.10, No.3, 2004. This is an integrated study that focuses on geomechanical modelling methodology. By means of a combination of simulation and subsequent verification against real pressure data within an overpressured petroleum basin, the authors have ably and effectively dealt with the complicated problem of predicting hydraulic fracturing and leakage over a geological time scale.

For their paper entitled "Multi-disciplinary study of the heavy-oil reservoirs in the Armatella Field, Sicily" which appeared in Petroleum Geoscience, Vol. 9, No. 3. This highly integrated reservoir study - based on laboratory fluid characterisation and being geologically constrained according to the structural evolution of SE Sicily - allowed a correct assessment of the reservoir geometry and of the field production behaviour. Using state-of-the-art methods for analysing the reservoir fracture network and properly designed modules for simulating non-conventional completions in a 3D dynamic model, it resulted into optimised drilling for draining undeveloped reserves.
