Introduction:

The Saih Hatat Structure is a large deeply eroded anticline, 80km x 50km elongated in the E-W direction, and located south of Muscat, on the eastern part of the Oman Mountains. The structure is bounded by allochthonous units of Ophiolite and deep oceanic sediments that were obducted in Late Cretaceous. During and after the obduction process, this area was subducted, along NE-dipping subduction zone, to deep crustal levels and was subsequently exhumated to surface, leading to intensive ductile deformation, under medium to high grade metamorphism, that could be clearly examined across the section of Wadi al Mayh. Mega-sheet folds, often described as the best and largest in the world, and numerous imbrications are clearly visible in this area within the Permian shelf carbonates. Along the northern contact between the ophiolite and the shelf carbonates of Saih Hatat, lie several hot springs, such as the Old Ghala spring and the al Hammam Spring. These springs emerge along a fault that separates the two rock masses. As rains falls, water percolates to considerable depth, gets heated and seeps back to surface along the fault zone.

Plan:

The field trip includes four main stops covered in one afternoon. We depart after the conference from the hotel by bus and head to our first location in Qantab, where the contact between the ophiolite and shelf carbonate is nicely exposed. We aim to be in Qantab at 4pm. We then drive through Wadi Yiti, to observe the large scale sheeth folds and low-angle detachment zones. Later, we will visit the hot water springs at the contact between the ophiolite and the shelf carbonates of Saih Hatat. We will finish the trip at about 6:15pm.

The lower Paleozoic sequences, from Cambrian to the lower Silurian are well exposed in southern Jordan; to the east of Aqaba. These are divided into eight formations in Jordan; the lower four formations belong to the so called Ram Group of Cambrian-Middle Ordovician age, with a total thickness up to 700m. The Ram Group rests unconformably on the granitoid rocks of the Arabian Shield. These sequences are composed of medium to coarse fluvial sandstones dominated by trough cross-bedding; with short intervals of marine incursions during Cambrian and Early Ordovician times; these marine incursions are indicated by the presence of thin siltstone beds bearing Cruziana trace fossils and vertical Skolithos Burrows.

The succeeding four sequences belong to the Khrayim Group of Middle Ordovician-Silurian age, with a total thickness up to 600m. This group is well exposed to the east of Wadi Rum and composed of shallow marine siliciclastics (sandstone, shale and mudstone); where the sandstone beds dominated by trough cross-bedding and ripple marks with Cruziana trace fossils, Skolithos Burrows and Brachiopods; whereas the mudstone beds bearing different species of Graptolites, Brachiopods and different undefined fossils.

In the middle of the Khrayim Group, by the end of Ordovician, the area was subjected and underwent a glacial event, where deep incision of glacial valleys cut through the older sequences of Ordovician and refilled by flovio-glacial sediments, which are formed the tight gas reservoir in Risha Gas Field in northeast Jordan. Regional marine transgression occurred in the early Silurian led to the deposition of a thick mudstone sequence called "Hot Shale" in Saudi Arabia, which is the proven source rock of the hydrocarbons in the Arabian Plate.

20-23 June 2017

Led by De Ville Wickens, PhD

Participants of this field excursion will be visiting one of the world's best examples of an ancient basin floor to slope fan complex associated with a fluvial-dominated deltaic system in the Karoo. Basin.

The Karoo basin hosts an inexhaustible amount of information on deepwater and deltaic sedimentation with present day erosion allowing 3D-viewing of laterally continuous (tens of kilometres) outcrops. The objective of this field trip is to attempt a better understanding of the basic depositional processes and facies development of deep-water sedimentation and the implications thereof for reservoir heterogeneity, lateral and vertical bed continuity and resulting reservoir architecture and quality. This two-day field trip will focus on show-casing the Whitehill and Dwyka formation, which are main targets for shale gas development in South Africa.

Wadi Al Khoud exposes a number of tectonostratigraphic units, including autochthonous siliciclastic and carbonate sediments that range in age from late Cretaceous to Quaternary. The main deposits in the area are divided into four formations, the late Cretaceous clastics of the Al Khoud Conglomerate Formation and the shallow marine carbonate units of the Al Jafnyn (Umm Er Radhuma in the subsurface), Al Rusail (Rus in the subsurface) and Al Seeb (Dammam in the subsurface) formations. These rocks uncoformably overlie a spectacular ophiolite succession which includes deep-oceanic sediments. The Oman ophiolite was thrust over the northern margin of Oman during the late Cretaceous orogenic event, resulting in the development of new sedimentation patterns, faults and fractures.

This fieldtrip will cover three main stops in Al Khoud village:

Stop 1: Deep-oceanic sediments and ophiolite.

Stop 2: The unconformity between the Al Khoud Formation and Al Jafnyn Formation.

Stop 3: Shallow marine carbonate sediments of Al Jafnyn, Al Rusail and Al Seeb Formations.

Stop 4: (optional) Foraminifera Graveyard.

In this fieldtrip, we will focus our discussions on the reservoir characteristics, seal potential and tectonostratigraphic evolution of this part of Oman. There will be a brief mention of the dinosaur collection found within the Al Khoud Conglomerate Formation and mineral usage of the limestones (Seeb) and gypsum (Rus) in cement manufacturing. If lucky, shark teeth might be found in the carbonates of the Seeb Formation.

The modern carbonate-evaporite depositional environments along the Abu Dhabi shoreline and offshore Abu Dhabi belong to the few areas of the world where the geoscientist can observe the interplay between carbonate and evaporite sedimentation.

Supratidal (sabkha) to intertidal and shallow subtidal (microbial mat and peloid-skeletal tidal-flat) environments will be studied in the vicinity of Al-Qanatir Island.

Al-Qanatir Island

In the vicinity of the road to Al-Qanatir Island participants will be able to study a complete and undisturbed lateral facies succession from the upper supratidal to the lower intertidal and shallow subtidal:

  • Upper supratidal stranded beach ridges
  • Topographic highs, some cm above the adjacent upper sabkha environment
  • Upper sabkha (upper supratidal)
  • Surface covered by polygonally-cracked halite crust
  • Middle sabkha (middle supratidal)
  • Surface covered by finely-crystalline, whitish anhydrite polygons
  • Lower sabkha (lower supratidal)
  • Surface covered by shiny, sparkling gypsum crystals
  • Upper to lower intertidal microbial mat
  • Crenulated or crinkled microbial mat above gypsum mush facies
  • Blistered and pinnacle microbial mat
  • Polygonal and tufted microbial mat
  • Lowermost intertidal to shallow sub-tidal
  • Peloid-skeletal tidal-flat

Many of these depositional environments and facies successions correspond to those observed in cores from the subsurface of the Arabian Peninsula.

The main objective of this field trip is to offer participants the opportunity to study the structural style and fracturing of carbonate rocks analogous to reservoir units of the globally important UAE Oil Province. The clear exposure of these carbonate rocks in this tectonically complicated area provides a significant opportunity to study and explain the structural style and deformation history of the region. Although the carbonate rocks exposed in Jebal Hafit area are of Early Eocene–Miocene age (Rus, Dammam and Asmari Formations), the emphasis here is to study fractures pattern and fracturing mechanism with relation to the paleostress and the link to fractures conductivity.

The selected stops will demonstrate the stratigraphic relationship of the rock units and their fracture systems that have been developed during long geological deformation. There are significant similarities between these exposed rocks and those units seen in the Abu Dhabi Oil Fields by means of reservoir characteristics and fracture system and fracture related diagenesis (cementation/host rock alteration) with its impact on sealing potential.

Jebal Hafit, an elongated asymmetrical, double‐plunging, NNW‐SSW trending anticline with an elevation reaches up to ~ 1140 m high, is situated at the border between Oman and UAE. It extends ca 30 km in the direction NNW–SSE with average width of 4 to 5 km.
