    Structural evolution of minibasins on the Utsira High, northern North Sea; implications for Jurassic sediment dispersal and reservoir distribution

    , Petroleum Geoscience, Vol: 16, Pages: 105-120

    3D seismic and well data are integrated to determine the tectonostratigraphicevolution of the SW margin of the Utsira High, northern North Sea riftsystem. During the Triassic, a series of minibasins formed due to passive diapirismof the evaporite-bearing, Upper Permian, Zechstein Supergroup. Subsequently,during the Jurassic, a series of secondary minibasins developed as the underlying saltwalls collapsed. These minibasins were a few hundred metres deep, bound bysub-circular to elongate salt-cored structural highs and caused the development ofcomplex subaerial topography and submarine bathymetry on the SW margin of theUtsira High. Salt withdrawal may have been related to: (i) partial dissolution of salt;(ii) differential erosion of the salt walls and adjacent Triassic-filled minibasins; or (iii)salt remigration caused by sub- or supra-salt extension or sediment loading. Thisstudy provides insights into the tectono-stratigraphic evolution of the SW margin ofthe Utsira High and has implications for (i) facies distribution of the ZechsteinSupergroup within the northern North Sea rift system; and (ii) depositional systemdevelopment, and thus reservoir distribution, within the Jurassic sedimentarysuccession.

    A two-phase adaptive finite element method for solid–fluidcoupling in complex geometries

    , International Journal for Numerical Methods in Fluids

    In this paper we present a method to solve the Navier–Stokes equations in complex geometries, suchas porous sands, using a finite-element solver but without the complexity of meshing the porous space.The method is based on treating the solid boundaries as a second fluid and solving a set of equationssimilar to those used for multi-fluid flow. When combined with anisotropic mesh adaptivity, it is possibleto resolve complex geometries starting with an arbitrary coarse mesh. The approach is validated bycomparing simulation results with available data in three test cases. In the first we simulate the flow pasta cylinder. The second test case compares the pressure drop in flow through random packs of sphereswith the Ergun equation. In the last case simulation results are compared with experimental data on theflow past a simplified vehicle model (Ahmed body) at high Reynolds number using large-eddy simulation(LES). Results are in good agreement with all three reference models.

    A constitutive model for the behaviour of shotcrete

    , Pages: 49-60

    A constitutive model for the behaviour of shotcrete is presented in this paper. It is formulated within the framework of elasto-plasticity and the smeared crack concept is applied. Two independent yield surfaces govern the mechanical behaviour under compression and tension, which is further controlled by non-linear hardening and softening. The main material parameters are assumed to change with time. Validation of the model has been achieved by fitting the increase in stiffness and strength to published data in the literature. Good agreement is found between predictions of the complete stress-strain curves of shotcrete at different ages and experimental results. The model represents a sophisticated tool for the realistic analysis of tunnels, which are driven according to the principles of the New Austrian Tunnelling Method (NATM).

    Sedimentology, stratigraphic occurrence and origin of linked debrites in the West Crocker Fm (Oligo-Miocene), Sabah, NW Borneo

    , Marine and Petroleum Geology, Vol: 26, Pages: 1957-1973

    The West Crocker Fm (Oligocene-Early Miocene), NW Borneo, consists of a large (>20000 km2) submarine fan deposited as part of an accretionary complex. A range of gravity-flow deposits are observed, the most significant of which are mud-poor, massive sandstones interpreted as turbidites and clast-rich, muddy sandstones and sandy mudstones interpreted as debrites. An upward transition from turbidite to debrite is commonly observed, with the contact being either gradational and planar, or sharp and highly erosive. Their repeated vertical relationship and the nature of the contact between them, these intervals are interpreted as being deposited from one flow event which consisted of two distinct flow phases (fully turbulent turbidity current and weakly turbulent to laminar debris flow). The associated bed is called a co-genetic turbidite-debrite, with the upper debrite interval termed a linked debrite. Linked debrites indicates are best developed in the non-channelised parts of the fan system, and are absent to poorly-developed in the proximal channel-levee and distal basin floor environments. Due to outcrop limitations, the genesis of linked debrites within the West Crocker Formation is unclear. Based on clast size and type, it seems likely that a weakly turbulent to laminar debris-flow flow phase was present when the flow event entered the basin. A change in flow behaviour may have led to deposition of a sand-rich unit with ‘turbidite’ characteristics, which was subsequently overlain by a mud-rich unit with ‘debrite’ characteristics. Flow transformation may have been enhanced by the disintegration and incorporation into the flow of muddy clasts derived from the upstream channel floor, channel mouth or from channel levee collapse. Lack of preservation of this debrite in proximal areas may indicate either bypass of this flow phase or that the available outcrops fail to capture the debris flow entry point. Establishing robust sedimentological c
