The driving forces for conventional accumulations (structural or stratigraphic traps) are Forces of Buoyancy which are due to differences in densities of hydrocarbons and water. In contrast, the driving forces for unconventional tight accumulations are Forces of Expulsion which are produced by high pressures. That is an enormous difference and creates unconventional petroleum systems that are characterized by very different and distinctive characteristics. The Force of Expulsion pressures are created by the significant increase in volume when any of the three main kerogen types are converted to hydrocarbons. At those conversion times in the burial history, the rocks are already sufficiently tight so the large volumes of generated hydrocarbons cannot efficiently escape through the existing tight pore system, thus creating a permeability bottleneck that produces an overpressured compartment over a large area corresponding to the proper thermal oil and gas maturities for that basin. The forces initially created in these source rocks can only go limited distances into adjacent tight reservoirs (clastics or carbonates) above or below the source. The exact distance will vary depending on the pressure increase, matrix permeability, and fractures of that specific tight reservoir system. In general, the distances are small, in the orders of 10s to 100s of feet for oil and larger for more mobile gas systems. Those exact distance numbers are subject to ongoing investigations.  

A plot of the pressure data versus elevation for a given formation is critical in determining whether an accumulation is conventional or unconventional. Conventional accumulations will have hydrocarbon columns of 10s to 100s of feet with the pressure in the hydrocarbons and that in the water equal at the bottom of the accumulation (at the HC-water contact). In contrast, the unconventional accumulations will show HC column heights of 1000s of feet with the pressure in the hydrocarbon phase and the water phase being the same at the top of the accumulation (at the updip transition zone). Those significant differences are critical for understanding and differentiating these two play types. Because the system is a pore throat bottleneck with very little or minimum lateral migration, the type of hydrocarbon s are closely tied to the thermal maturity required to generate those hydrocarbons. Thus the play concept begins with two important geochemical considerations: (1) where are the source rocks and what are the kerogen types and organic richness (TOC), and (2 ) where are they mature in the basin for oil, condensate, and gas in the basin. These parameters will very quickly define the fairway for the play. Then one has to add the critical information on the reservoirs themselves: composition (brittleness), thickness, and reservoir quality (matrix porosity and permeability). In summary, these tight unconventional petroleum systems (1) are dynamic , and (2) create a regionally inverted petroleum system with water over oil over condensate over gas for source rocks wit h Type I or II kerogen types.

Field Trip Date: 10 May
Field Trip Time: 3pm - 7pm
Field Trip Leader: Mohammed Al Kindi, GSO

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.

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.
