Basin and petroleum systems modelling to characterise multi-source hydrocarbon generation: A case study on the inner Moray Firth, UK North Sea

J. R. Perkins et al.

Summary: In this paper, basin and petroleum systems modelling (BPSM) was used to investigate the Inner Moray Firth in the UK North Sea. The study aimed to identify the contributions of different source rocks, mixing ratios of accumulated hydrocarbons, and migration pathways of charging the three known fields in the basin - Beatrice, Jacky and Lybster fields. The results indicate that extensive faulting plays a key role in hydrocarbon migration and accumulation, the accumulations in the basin do not contain Kimmeridge Clay Formation oil, and the mixing ratio is approximately 65:35 for Devonian Fish Bed vs Pentland Formation contribution. Migration modelling suggests that Beatrice Field was charged predominantly by proximally sourced hydrocarbons, whereas Jacky and Lybster fields were charged by a near-even mix of proximal and deep-basin hydrocarbons from the Great Glen Sub-Basin.

Explicit representation of natural fractures in modelling of fluid flow within source rocks-A Longmaxi Shale multiscale multiphysics unification case study

Clay Kurison

Summary: This study investigates the impact of natural fractures on shale reservoirs using various methods and data. The linear flow parameters and system permeability were derived from production data and microseismic events. The results were validated using different techniques and data, and qualitatively compared with other interpretations. The study shows that natural fractures have a significant influence on reservoir flow.

3D petroleum systems modelling as an exploration tool in mature basins: A study from the Central North SeaUK.

S. A. Badejo et al.

Summary: This paper applies 3D petroleum systems modelling and rock magnetic analysis to reassess the hydrocarbon migration system in the Central North Sea, UK. The study focuses on the Tay Sandstones as a laboratory for studying vertical and lateral migration. The identification of untested prospects in the Gannet and Guillemot complexes highlights the value of this integrated approach in promoting new thinking and critical testing of conventional models.

Basin and petroleum systems modelling in the northern Norwegian Barents Sea

Rudiger Lutz et al.

Summary: The Olga Basin, located in the northern Barents Sea, shows signs of active petroleum systems with gas seepage, but the impact of erosion on petroleum generation remains debated.
