Carbonate pore structure and therefore permeability is controlled in large part by unique diagenetic events and products, and a complex wettability structure that is often dominantly weakly-oil wet. This produces a highly diverse array of pore types and size, styles of connectivity and tortuosity, and in turn flow behaviours. While changes in porosity can be directly related to diagenetic petrographic characteristics such as cement distribution and dissolution features, quantifying how these textures control attendant changes in permeability ismore challenging. The impact of individual diagenetic events and their products on flow properties can, however, be isolated and modelled using 3D pore architecture models.

Porosity and permeability evolution through many diagenetic scenarios often display several ‘diagenetic tipping points’ where the decrease in permeability is dramatically larger than expected for the associated decrease in porosity. The effects of diagenesis also alters the capillary entry pressures and relative permeabilities, so providing trends that can be applied to real rocks. In turn, such diagenetic pathway models can be used to provide constraints on predicted flow behaviour during burial and/or uplift scenarios using ‘diagenetic back stripping’ of carbonate rocks. In dominantly microporous carbonates, average pore radius controls single-phase permeability, but has minimal effect on multiphase flow. When moldic mesopores are added to a microporous matrix, they only impact flow when directly connected: micropores control the magnitude of single-phase permeability. Recovery, however, is dependent on both wetting scenario and pore network homogeneity: under water-wet imbibition, increasing proportions of microporosity yield lower residual oil saturations.

Process-based models of early cementation (isopachous and syntaxial) show that isopachous cement is effective in closing pore throats and limiting permeability, but permeability changes due to syntaxial cement growth (preferentially on monocrystalline grains) is highly dependent on monocrystalline grain location and direction ofthe grain crystal axis, as this can create a highly ‘patchy’ distribution of cement.

The West Texas (Permian) Basin is a complexly structured intracratonic (IC) basin with prolific oil and natural gas production. It began as a subsidence basin ('Tobosa Basin') from Middle Ordovician to Devonian time, a response to the Cambrian rifting that separated Gondwana and Laurentia. In the Pennsylvanian to early Permian, it formed part of the Ancestral Rocky Mountains (ARM) orogen. The Texas-New Mexico segment of the ARM contains small to medium basement-cored uplifts, folds, thrust faults and two trends of strike-slip faults, with a pattern that is consistent with SW-NE compression. The largest thrust fault known in the basin is SW-vergent, and faces the deepest part of the Delaware Basin. This direction of compression is similar to that observed in the southern Oklahoma part of the ARM, which shows NE-vergent thrusting and left-lateral faulting.

This SW-NE compressive stress is grossly inconsistent with the northwestward convergence of the Ouachita-Marathon thrust belt southeast of the ARM. The ARM-generating stress may have originated either from the Pacific side (by flat subduction) or from strong continental collision in the Appalachian Orogen. Lines of weakness generated during the Proterozoic and/or Cambrian concentrated stress and created the complex structures.

The West Texas branch of the ARM is buried by over 2.5 km of post-deformational Permian strata -- the Permian Basin. Subsidence began during ARM deformation, then increased in rate and continued to the end of the Permian. Permian subsidence resulted in the maintenance of isolated deep-water marine basins until Late Permian time. The Marathon orogen also subsided, and shed little clastic material into the basin. Despite Mesozoic basin-margin modifications, the Permian isopach pattern suggests a bowl-shaped subsidence centered on the Central Basin axis of uplift. The size and shape of the Permian Basin are similar to other IC basins (Illinois, Michigan, Williston). Similar to some IC basins, the central basin area hosts a 1100-Ma mafic complex, which was subjected to compression in Pennsylvanian time. Sinking of a mafic crust or its subjacent lithosphere, begun during compression, may have been a driving force for Permian subsidence.

Over most of the basin, later Permian subsidence was responsible for putting source rocks into the oil window. Further maturation to gas occurred within the deep basins generated by ARM deformation and Marathon thrust loading.

Our ability to predict reservoir presence or map net reservoir in clastic depositional systems is dependent on our understanding of the depositional geometries of the various depositional systems and the variation of patterns within those systems. The processes associated with sediment delivery and sediment dispersal is the fundamental control on the architectural geometry of a depositional system. The processes associated with the interplay between sediment input and accommodation space are the fundamental controls on the lateral and vertical stacking patterns within that geometry.

The geometry of the depositional system is similar regardless of the depositional location or scale. As such, the patterns within the geometries are also similar, and, therefore, predictable. This is a powerful concept that the interpreter can use in predicting depositional geometries and patterns. Whether the reservoir being studied was deposited on land or on a submarine fan, or whether it is 100’s of kilometers in scale or a kilometer, the geometry of the deposit is similar. Therefore, interpreters need only become familiar with the basic geometries of clastic depositional systems and the patterns that occur within those geometries.

Modern and outcrop analogs will be used, along with subsurface examples to provide the interpreter with a sound understanding of the reservoir distribution and quality, both laterally and vertically of the clastic depositional systems most commonly encountered as oil and gas reservoirs. The course is exercise-oriented and taught in PowerPoint format. A course manual is provided. The exercises in this course are designed to give you a strong working knowledge of the many depositional settings you are likely to encounter in your career. They are aimed at helping you to learn how to recognize them from well logs, and how to map them.

Field Trip Leader: Abdallah Aitsalem (ONHYM) & Lahcen Boutib (ONHYM)
Field Trip Fee: USD575 *

* Field trip pricing covers accommodation, feeding and transportation for the duration of the Trip. Seats are limited and will be confirmed on a first come first served basis.

Day 1 Departure from Marrakech to Ouarzazate

The Atlas Mountains of Marrakech extend more than 250 km East-West and 50 km North-South. They record the highest mountainous peaks in North Africa with altitudes exceeding 4,000 meters (Toubkal 4,165m and Ouenkrim 4,089m). Northward and southward, they rise hundreds of meters above the Marrakech plain (Haouz plain) and Imini syncline, respectively. The recently incised mountain valleys, created during the last inversion of the Atlas, form the crossing ways of the massif, as is the case of the main road that connects Marrakech to Ouarzazate passing via the Tizi n'Tichka Pass. They also provide the opportunity to view multiple breathtaking landscapes and contain outcrops that shed light on the geological evolution of the mountain from the Precambrian to the present. Day 1 of the field trip will allow participants to view Paleozoic outcrops through the Tizi n'Tichka Pass, which displays a complete Cambrian to Devonian succession and contains several organic-rich intervals. Mesozoic and Cenozoic deposits, which are exposed on the borders of the massif, will also be viewed briefly.

Day 2: Departure from Ouarzazate to Tazzarine and back to Ouarzazate **

Day 2 of the field trip crosses the central Anti-Atlas Paleozoic basin and offers spectacular views of the largest oasis in North Africa, along the Draa River, and its majestic ancient Kasbahs. Participants will examine formations ranging in age from Upper Precambrian to Silurian. Discussions will focus on the evolution of their various depositional environments in relation to sea level changes. The well exposed sandstone formations provide the opportunity to view major Paleozoic reservoirsintervals, as well as the organic-rich "hot shales" that source these reservoirs. Rubble from recent water wells and ingenious sub-cropping irrigation systems (Khattara) provide the chance to sample fresh Ordovician and Silurian organic-rich and fossiliferous black shales. In addition, the participants will have perspective views of gentle folding generated during the Hercynian compression and related regional fractures.

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.

This three-day workshop builds on the success of the first AAPG Carbonate Reservoirs of the Middle East GTW, held in Abu Dhabi, UAE in 2015. It is dedicated to addressing the hydrocarbon bearing carbonate reservoirs of the Middle East, in the context of a changing oil market within a more challenging exploration and development environment. These challenges include the shift from traditional anticlinal traps to stratigraphic traps, and development strategies for dealing with maturing, long-producing, giant fields.

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.

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 Ice Age and the Giant Bakken Oil Accumulation

The USGS estimated (2013) that the Late Devonian to Early Mississippian Bakken Formation holds in excess of 7 billion barrels (~1.1 billion m3) of recoverable oil, making it one of the top 50 largest oilfields in the world. Most of the production comes from shallow-marine sandstones of the Middle Bakken Member that are directly over- and underlain by extremely organic-rich shale source rocks (Upper and Lower Bakken Shale members respectively). Although not oil-productive everywhere, the Middle Bakken forms a relatively sheet-like unit that covers an area of over 200,000 square miles (~520,000 km2) of the intracratonic Williston Basin.

The vertical juxtaposition of shallow-marine reservoir and more distal source rocks over such a large area, without intervening transitional facies, is unusual from a stratigraphic perspective. One possible explanation would require global fluctuations of sea level to drive geologically rapid and extensive shoreline movements in this relatively stable basin. Forced regression associated with falling sea level could explain the lack of transitional facies (e.g., inner shelf) between the distal Lower Bakken Shale and the overlying Middle Bakken (a sharp-based shoreface). Subsequent sea-level rise would have caused rapid and extensive transgression, leading to the observed stratigraphic relationships between the Middle and Upper Bakken members. But what could have caused the changes in sea level?

A considerable body of evidence points to a Late Devonian-Early Mississippian ice age that covered portions of Gondwana (e.g., parts of present-day Brazil) that were situated close to the paleo South Pole. This ice age consisted of more than one glacial/interglacial cycle and was probably triggered by massive removal of CO2 from the atmosphere by land plants and organic-rich shales. Some evidence indicates that at least 100 m of sea-level drop took place during one of the Famennian glaciations, which would have effectively drained the Williston Basin and induced major shoreline progradation. Melting of the ice sheets would have caused transgression and reflooding of the basin and deposition of the Upper Bakken Shale. Other basins around the world record similar evidence for glacioeustacy near the Devonian-Mississippian transition. The glacial/interglacial cycles are expressed differently from basin to basin, reflecting the interplay between fluctuations of global sea level and each basin’s history of subsidence and sediment supply.
