“…The PhaseKinetics model characterizes the compositional evolution of the fluids generated with increasing thermal stress, as well as the phase behaviour of the petroleum at different maturity levels (Di Primio & Horsfield 2006). Predictions of bulk petroleum compositions and physical properties have already been published for basins in South Africa (Hartwig et al 2012), North Dakota (Kuhn et al 2012), Norway (Rodrigues Duran et al 2013, eastern Canada (Baur et al 2010), Brazil (Di Primio & Horsfield 2006 and China (Tan et al 2013), in several cases with confirmation of the prediction using local calibration. In the current study we employed the PhaseKinetics approach on both whole-rock samples and kerogen concentrates to predict the properties of fluids generated from Bowland Shale, also taking into consideration the impact of rock-fluid interactions (mineral matrix effects, considered to be laboratory artefects) on the results (see Espitalie et al 1980;Horsfield & Douglas 1980).…”

The Carboniferous Bowland Shale of northern England has drawn considerable attention because it has been estimated to have 1329 trillion cubic feet hydrocarbons in-place (gas and liquids) resource potential (Andrews 2013). Here we report on the oil and gas generation characteristics of three selected Bowland Shale whole-rock samples taken from cores and their respective kerogen concentrates. Compositional kinetics and phase properties of the primary and secondary fluids were calculated through the PhaseKinetics and GOR-Fit approaches and PVT modelling software. The three Bowland Shale samples contain immature, marine type II kerogen. Pyrolysate compositions imply primary generation of paraffinic–naphthenic–aromatic (PNA) oil with low contents of wax and sulphur. Bulk kinetic parameters have many similarities to those of productive American Palaeozoic marine shale plays. The secondary gas generation potential of Bowland Shale is greater than the primary gas potential although it requires a 10 kcal mol −1 higher activation energy to achieve peak production. Primary oil, primary gas and secondary gas reach their maximum generation at 137, 150 and 200°C respectively for a 3°C Ma −1 heating rate. Different driving forces of expulsion including the generation of hydrocarbon and overpressure caused by phase separation during sequential periods of subsidence and uplift could be inferred.

“…Rank profiles and rank maps ilustrating the regional rank variations (e.g., Suárez-Ruiz and Prado, 1995;Colmenero et al, 2008;Ruppert et al, 2010) provide important information in basin studies and modeling. Detailed research focused on the palaeogeography and/or the palaeothermal conditions during the geological evolution of basins all over the world have been reported (e.g.,) by Büker et al (1996); Baur et al (2010).…”

“…Carr (2003 noticed that in overpressure systems a pressure-dependent kinetic model should be used for modeling. Models based on heat flow but also including data on compaction, pressure, temperature, maturation of organic matter, petroleum generation, migration and accumulation through time have been used to simulate the burial history of sediments by Tissot and Welte (1984); Baur et al (2010), among others. However, in tectonically active basins, the resulting maturation patterns are the sum of a wide set of processes that should be taken into account in basin modeling.…”

“…There is often significant uncertainty in basin geometry and depth of stratigraphic horizons based on uncertain seismic interpretation and velocity models (Kukla et al, 2000;Brandes et al, 2008;Baur et al, 2010). Restoring of present-day geometries to obtain paleogeometries adds further uncertainty.…”

A B S T R A C TConventional basin and petroleum systems modeling uses the vertical backstripping approach to describe the structural evolution of a basin. In structurally complex regions, this is not sufficient. If lateral rock movement and faulting are inputs, the basin and petroleum systems modeling should be performed using structurally restored models. This requires a specific methodology to simulate rock stress, pore pressure, and compaction, followed by the modeling of the thermal history and the petroleum systems. We demonstrate the strength of this approach in a case study from the Monagas fold and thrust belt (Eastern Venezuela Basin). The different petroleum systems have been evaluated through geologic time within a pressure and temperature framework. Particular emphasis has been given to investigating structural dependencies of the petroleum systems such as the relationship between thrusting and hydrocarbon generation, dynamic structure-related migration pathways, and the general impact of deformation. We also focus on seal integrity through geologic time by using two independent methods: forward rock stress simulation and fault activity analysis. We describe the uncertainty that is introduced by replacing backstripped paleogeometry with structural restoration, and discuss decompaction adequacy. We have built two end-member scenarios using structural restoration, one assuming hydrostatic decompaction, and one neglecting it. We have quantified the impact through geologic time of both scenarios by analyzing important parameters such as rock matrix mass balance, source rock burial depth, temperature, and transformation ratio.Ralf Littke received his diploma in geology and Ph.D. at Ruhr-University Bochum (Germany). He is professor of geology and geochemistry of petroleum and coal and currently dean of the faculty of Georesources and Material Science at RWTH Aachen University. His research interests include sedimentary basin dynamics, petroleum and source rock geochemistry, porosity and permeability of lowpermeability rocks, natural gas geochemistry, organic petrology, petroleum system modeling, and petroleum geology.
