A few months after the founding of AAPG in early 1917, the first description of the Wolfcamp Formation was published in the University of Texas Bulletin No. 1753 titled “Notes on the Geology of the Glass Mountains” by J. A. Udden, on Sept. 20, 1917.

Last year, the extraordinarily high quality of the technical program was the talk of the AAPG Annual Convention and Exhibition in Calgary, and this was at an ACE with plenty of high points to talk about. The technical program for the 2017 ACE in Houston promises to be even better than last year’s.

Rock-Eval hydrogen index (HI) is often used to compare relative maturities of a source horizon across a basin. Usually, there are several measurements from the source horizon at a single well, and the mean hydrogen index is calculated, or the S2 is plotted against TOC. The slope of the best fit line through that data is used as the representative HI for that well (sometimes referred to as the ‘slope HI ’ methodology). There is a potential flaw in both these methodologies; however, that renders the calculated HI as misleading if the source horizon being examined is not relatively uniform in source quality, vertically in the stratigraphic column. From a geologic perspective, it would be unusual for the source rock quality not to vary vertically in the stratigraphic column. Organic matter input, preservation, dilution, and sediment accumulation rate typically vary in many depositional environments over the millions of years required to create a thick source rock package. Nevertheless, there are source rocks which do display remarkable source-quality uniformity from top to bottom of the stratigraphic package. We have examined source rocks from several basins where the source quality is relatively uniform over the stratigraphic column, and source rocks where the source quality varies greatly over the stratigraphic column. Methodologies to assess hydrogen index at specific wells for the se two scenarios differ. Most geoscientists may not be familiar with why a single technique is not suitable for both these scenarios, or how to correctly use hydrogen index as a relative maturation proxy in the case where source rock quality is not uniform. We will demonstrate how to determine if your source rock quality is uniform or varied relative to HI over the stratigraphic column, and how to assign a hydrogen index to the different source facies when that source rock quality is not uniform. Further we will illustrate how to estimate the original hydrogen index of the different source facies and assign each a transformation ratio. The transformation ratio is a better proxy for relative maturity, since different source facies may have different present-day hydrogen indices, but their present-day transformation ratio should be quite similar.

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: 4pm - 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.

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.

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.
