“…Patterns of smaller-scale linear structures have been identified on the topographic high regions near the Samhain Catenae (Fig. 6E), which are consistent with models of asymmetrical domal uplift (31). This system shows apparent broad outer arc extension, with at least two central peaks (Fig.…”

Analysis of Dawn spacecraft Framing Camera image data allows evaluation of the topography and geomorphology of features on the surface of Ceres. The dwarf planet is dominated by numerous craters, but other features are also common. Linear structures include both those associated with impact craters and those that do not appear to have any correlation to an impact event. Abundant lobate flows are identified, and numerous domical features are found at a range of scales. Features suggestive of near-surface ice, cryomagmatism, and cryovolcanism have been identified. Although spectroscopic analysis has currently detected surface water ice at only one location on Ceres, the identification of these potentially ice-related features suggests that there may be at least some ice in localized regions in the crust.

“…Physical analogue modelling techniques have been proven to provide robust simulations of a wide variety of tectonic and geological features and processes from global-or regionalscale crustal studies to outcrop and sub-metrescale processes (e.g. Cadell 1888; Hubbert 1937, Ramberg 1963Mulugeta 1988;Koyi 1997;Rahe et al 1998;Wyrick et al 2011;Byrne et al 2013;Sims et al 2013). Among the most important strengths of physical analogue modelling are: (1) the capability to model complex three-dimensional configurations; (2) the capacity to simulate discontinuous processes such as fracturing and faulting; and (3) the ability to document evolving deformation over time.…”

“…Faults produced in these analogue materials are geometrically and kinematically similar to those observed in terrestrial fault systems (Rahe et al 1998;Wyrick et al 2011;Sims et al 2013). Although the absolute values of the principal stresses are not measurable, the experiments were set up so that the maximum principal compressive stress s 1 was vertical and the relative magnitudes of the initial minimum principal stress s 3 were controlled by varying boundary constraints.…”

Physical analogue modelling of Martian dyke-induced deformation

The Tharsis region of Mars is characterized by large volcanic and tectonic centres that have been active throughout Martian geological history, including distinct sets of graben that extend radially for distances of hundreds to thousands of kilometres. Formation of these graben has been attributed to crustal extension and/or dyke propagation. Physical analogue models using layered sand and liquid paraffin wax were constructed to test the magnitude and style of deformation in the host rock associated with dyke injection. A variety of igneous morphologies was produced, including dykes and plugs. Results suggest that, in the absence of pre-existing faults, vertical dykes do not produce significant deformation in the surrounding rock. Deformation associated with other magmatic intrusions produced primarily contractional features rather than extensional features, similar to previous numerical studies and terrestrial field investigations.Gold Open Access: This article is published under the terms of the CC-BY 3.0 license.

“…This mechanism is however not sufficient to explain the occurrence of the two sub-perpendicular fault sets. Such pattern can be interpreted as resulting from combined sequences of regional extension and uplift (diapir related), as proposed by Yamada et al (2005), and by Sims et al (2013) after their analogic modeling, as well as by Edwards et al (2006) after their 3D structural seismic analysis of an Abu Dhabi offshore field.…”

The giant field considered in this paper, located offshore Abu Dhabi, has so far been developed with solely a pressure maintenance-oriented strategy despite having produced for nearly fifty years. Such achievement has been possible because the field, divided into three stacked isolated reservoirs, is relatively homogeneous with little-to-no flow barriers.The purpose of this paper is two-fold. First, propose a review and critical discussion of the different pressure maintenance methods employed so far, which chronologically include gravity-driven dumpflood water injection, peripheral powered water injection, and down-flank as well as crestal gas injection.Second, present a segmentation mainly based on pressure trends on which injection-production metrics can be computed to help reservoir management pinpoint areas lacking support. A key to such analysis in the presence of peripheral water injection is to account for efficient water only, i.e., discard losses to the aquifer. For this purpose, a workflow involving streamline based post-processing of reservoir simulations corroborated by material balance analysis is used.Recent increasing trends in WCT and GOR indicate that a development solely based on pressure maintenance and reservoir energy (i.e., without artificial lift) is not sustainable anymore, and must transition to sweep-oriented. Plans for such migration are discussed in the companion paper of Nakashima et al. (SPE-177801).
