dd{line-height: 23px;} Field Trip Leader De Ville Wickens, Geo-Routes Petroleum Start/Return Cape Town, SA Fee $1495 (including all local taxes and VAT) Registration Deadline 5 December 2021 Price Includes 2 nights accommodation at Inverdoorn Game Reserve Lodge, all F&B, transportation and entry fees to farms Participants of this field excursion will be visiting the world's best example of an ancient fine-grained basin floor to slope fan complex associated with a fluvial-dominated deltaic system. The Permian Tanqua Fan Complex of the southwestern Karoo Basin has served as analogue for many deep-water systems around the world and continues to be the most sought after “open-air laboratory” for studying the nature of fine-grained deep-water sedimentation. The fan systems are tectonically undeformed, outstandingly well exposed and easily accessible with present day erosion allowing 3D-viewing of laterally continuous (tens of kilometers) outcrops. It hosts an inexhaustible amount of information on deep-water element architecture from lower slope channel complexes to extensively developed basin floor deposits. Who Should Attend This field trip is targeted at exploration and development geologists, geophysicists, reservoir engineers and managers who are actively involved in deep-water exploration and development. It will also benefit those unfamiliar with deep-water systems. Objectives The prime objective of this field trip is to attempt a better understanding and appreciation of the depositional processes and facies distribution within fine-grained deep-water fan systems and the implication thereof for reservoir and non-reservoir distribution, their architecture, heterogeneity and quality. It further aims to integrate different scales of observation and interpretation, namely the basin (exploration) scale (e.g. sequence expression on the basin floor, sequence stacking, influences of basin floor topography) and the development and production scale (e.g. facies/element/heterogeneity distribution, stacking patterns, bed-scale stratigraphy, hierarchy of architectural elements) within distributive deep-water systems. Itinerary Day 1: 10th February 07:30 Depart from Cape Town to the Ceres Karoo. Drive through the Cape Fold Belt region via Bains Kloof Pass, Ceres and Cedarberg Mountains to Inverdoorn Game Reserve.

Trip leader(s): Josep Anton Muñoz, Pablo Granado and Eduard Roca Limit: 20 Participants The aim of this 2-day field trip is the recognition of the key structural features of a fold and thrust belt detached on salt that has resulted from the inversion of a previous passive margin. To achieve this objective, some of the key and most spectacular localities of the southern Pyrenees have been selected along the ECORS-Pyrenees transect. This is a reference cross-section provided that for many years a huge amount of geological and geophysical data sets has been collected and integrating into a kinematic model of the South-Pyrenean fold and thrust belt. Subsurface data (well logs and seismic sections) will be combined with field observations. One of the main characteristics of the southern Pyrenees is the preservation of the synorogenic sediments since the earlier stages of deformation, which not only provide time constraints but also allow us discussion of kinematics of fault-related folds and thrust systems. Finally, the mild contractional deformation permits deciphering the initial geometry of the rift system and the salt structures that configure the structural grain of the passive margin before the inversion, allowing discussion of the role that these structures play during the fold and thrust belt development. Itinerary: (day by day details of the trip) Day 1 Stop 1.1: The South-Pyrenean thrust front. Sant Llorenç de Montgai Structure of a frontal thrust system and related unconformities. Out of sequence thrusts and synorogenic sediments. The frontal thrust system of the South-central Pyrenees has been detached into the Triassic evaporites and involves a thin Mesozoic succession. It is characterized by an emergent thrust system during the sedimentation of upper Eocene and lower Oligocene continental sediments. Frontal thrusts were progressively buried by conglomerates, triggering a break-back thrusting sequence and the development of out-of-sequence thrusts bringing together strongly different Mesozoic successions, such as the Montroig thrust in the picture. Stop 1.2: The Ager basin and the Montsec thrust sheet. Fontllonga The Ager basin in the footwall of the Montsec thrust. The Montsec thrust sheet developed from the Paleocene to the Early Eocene as recorded by continental to shallow marine sediments deposited in its footwall (Ager basin) as well as in the Tremp-Graus piggy-back basin. The lower Eocene sediments of these basins grade westward into the slope succession filling the Ainsa basin at the footwall of the Montsec thrust. Stop 1.3: The frontal structure of the Montsec thrust sheet. Ametlla (optional: Montrebei) Fault-propagation fold related with the inversion of Early Cretaceous extensional faults and growth deltaic sediments in the footwall syncline. The Montsec thrust sheet involves the northern part of the Upper Cretaceous foreland basin characterised by a strong subsident turbiditic trough at the footwall of the Bóixols thrust. These turbidites grade southward into a carbonatic platform that constitutes the backbone of the Montsec Range (main ridge and cliff of the pictures). Underneath the Upper Cretaceous carbonates, some Early Cretaceous extensional faults are preserved in the hanging wall of the Montsec thrust, but others have controlled the development of a hanging wall frontal anticline. The geometry of this anticline as well as the structure of the growth sediments in the footwall Ager syncline are visible in the field. The subthrust geometry will be discussed integrating surface observations and the available seismic and well data. Overnight in Tremp Day 2 Stop 2.1: The Sant Corneli-Bóixols anticline Inversion of the rift margin The Sant Corneli-Bóixols anticline is the most prominent frontal structure of the Bóixols thrust sheet in the central Pyrenees. This fold trends east–west and crops out for greater than 40 km along strike. The Sant Corneli-Bóixols anticline involves a thick Mesozoic succession detached on top of Triassic evaporites. The prefolding sequence consists of up to 5 km of prerift, synrift, and postrift carbonates ranging in age from Jurassic to Upper Cretaceous. Synfolding Upper Cretaceous sediments start with the upper Santonian carbonates and continue with a succession of Campanian and Maastrichtian marls and turbidites. The Sant Corneli–Bóixols anticline is an example of an inversion fold developed along the rift margin of the Lower Cretaceous basin. Its geometry is related with the inverted extensional system. In particular, the three-dimensional geometry, including the saddles between culminations, is inherited from the previous transfer faults of the segmented rift margin. Available seismic data and 3 exploratory wells constrain the geometry at depth. Stop 2.2: The synororgenic Paleogene conglomerates Inverted Lower Cretaceous basin and Eocene-Oligocene synorogenic conglomerates at Collegats gorge. Stop 2.3 (optional): The Sopeira and Aulet minibasins. Sopeira Minibasins developed by extensional collapse and salt evacuation during the thermal subsidence at the southern Pyrenean rift margin. Inversion of these mini-basins at the early stages of Pyrenean contractional deformation during Late Cretaceous. Additional logistic information Transportation Transportation will be with a small bus, assisted by minivans to have access to some of the outcrops. Physical demand, equipment and safety This is an easy field trip with very easy and limited hikes to get to the outcrops. Outcrops will be from main sealed roads. Safety vests will be available, to be used by everybody of the group wherever required and asked to. There will be First Aid Kits available in each car during fieldwork. Climate The climate during mid-end November in the fieldwork area can be cold and rainy, although dry and sunny days may occur as well. The temperature for November in Tremp can range between 30C and 170C. Participants should be prepared in case we should encounter bad weather and you should bring warm and waterproof clothes and suitable hiking boots. -->

Instructors: Ricardo Pereira, (PARTEX Oil and Gas & Instituto Dom Luiz) Gil Machado (ChronSurveys Lda & Instituto Dom Luiz) Fees: To be determined Includes: Hotel Ground Transporation Snacks and Refreshments Lunch and Dinner Guidebook Departure Time/Location 16 May 2020 8:30am SANA Metropolitan Hotel Note:Transportation to start point is not included in the costs of this trip. Please bring clothing for hot day time temperatures (sun hat/ sun glasses/ sun cream etc.). Participants must wear suitable and comfortable light trekking shoes. Aims To gain or increase an understanding of the tectono-sedimentary processes of continental extension and rifting supported by outcrop observations, with focus on deep-depositional marine systems. Discuss implications for prospective petroleum systems. Promote debate and nourish new insights between attendants. About the Field Trip The Lusitanian Basin records the proximal events of syn- to post rift evolution of the hyper-extended West Iberian Margin, showing some outstanding examples of the combined tectono-stratigraphic depositional systems. Here, the Late Jurassic reveals diverse aspects of mixed marine depositional systems including not only submarine fans and turbidites, but also the build-up of carbonate reefs and shoreface to fluvial clastic sequences. Throughout the fieldtrip the different depositional aspects can be observed in detail to demonstrate how such depositional systems can vary in time and space. Observation of these outcrops allows a better understanding on how deep-water depositional systems can change within a sub-basin and help improving the understanding of reservoir properties.
