3rd Edition: Carbonate Reservoirs of the Middle East

28-29 January 2020
Abu Dhabi, United Arab Emirates
Sponsored By:

The 2020 AAPG Carbonate Reservoirs of the Middle East workshop is the third event of this series, which will be held in Abu Dhabi, from 28th to 29th January. It will give the opportunity for operators, service companies and researchers to discuss common challenges related to carbonate reservoirs, and their solution through the application of innovative technologies. Although, the topics will clearly encourage attendance from specialists based in the Middle East region, we also expect a global audience that includes promotors and practitioners of carbonate analysis. This is a reflection of its increasing role in the various stages of exploration and development: from exploration drilling to well performance in field development.

Carbonate reservoirs have been important contributors to world oil and gas production for more than four decades (45 % of oil and 30 % of gas reserves, while in the Middle East hosting 80% and 90%, respectively). Carbonate rocks are found in a wide variety of depositional settings. These settings range from basinal pinnacle reefs covering only a few kilometres, to hundreds of kilometres through large isolated carbonate banks/platforms, to giant land-attached carbonate platforms that often extend over thousands of square kilometres. The carbonate sediments have been affected by diagenetic alterations coupled with tectonic stresses, leading to a multiscale heterogeneity within the reservoirs. This makes it complex to carry out the spatial modelling of the geological and petrophysical properties across the reservoirs and a challenge to predict the right dynamic behavior.

Workshop Objectives

The workshop aims to gather subsurface professionals from the oil and gas industry and academia across the region from different disciplines (geology, geophysics, petrophysics and reservoir engineering), to share their knowledge, experience, up-to date technologies and best practices. The workshop will consist of two days comprising of presentations, poster sessions and core displays, followed by a third day offering two optional field trips to the Abu Dhabi Sabkha, and Tertiary outcrops of Jebel Hafit.

Benefits of Attending

The workshop is a great opportunity for attendees to learn and get influence on up-to-date innovative approaches for carbonate reservoir characterization. In addition to that, this workshop is a technical platform for sharing the research experiences among the oil and gas professionals and academia, where they can address several reservoir challenges, discuss case studies and provide the best solutions to overcome these challenges. Also, the attendees during the workshop can be interactively engaged in selective topics during the breakout sessions.

Who should attend?

This workshop is intended for geologists, geophysicists, petrophysicists, reservoir engineers, academic researchers, and decision makers working on the exploration, appraisal and development of carbonate hydrocarbon reservoirs.

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.

The analysis of modern analogs is one of the few means by which high-resolution spatial complexity of stratigraphic systems can be described. If the horizontal dimensions of facies belts are less than the typical well spacing, modern analogs, together with seismic and production data help to construct realistic geologic and simulation models of subsurface reservoirs.

Supratidal (sabkha) to intertidal (microbial mat), and lowermost intertidal to shallow subtidal (lagoon: skeletal-peloid tidal-flat) environments will be studied along the Abu Dhabi coastline 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 of the upper supratidal to the shallow subtidal environments:

  • 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 subtidal.
    • Peloid-skeletal tidal-flat.

This trip provides an insight into recent to modern evaporitic coastal depositional systems, that can be considered analogues to parts of the Mesozoic reservoir systems of the Middle East (e.g. intra-Arab & Hith anhydrites).

8:00 am Depart for Sabkha outcrops at Al-Qanatir
9:00 am Arrive at Al-Qanatir Island
9:15 am Introduction
Stop 1: Lateral Sabkha Sequence

The one day field trip to Jabal Hafit is tailored 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, with emphasis to study fractures pattern and fracturing mechanism with relation to the paleostress and in‐situ stresses, and the link to fractures hydraulic conductivity.

The proposed locations to be visited on this fieldtrip will demonstrate the stratigraphic relationship of the various 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 depositional characteristics and fracture system and fracture related diagenesis (cementation/host rock alteration) with its impact on sealing potential.

List of the observation stops made over Jabal Hafit with their GPS record, lithology and structures:

Unconventional Shilaif “Shale Oil” and Diyab “Shale Gas” Core Display

Following geological screening studies two Mesozoic source rock intervals were identified as having the highest potential for commercial Unconventional Hydrocarbon Resources: Shilaif fm (Middle Cretaceous) and Diyab fm (Late Jurassic) in Abu Dhabi.

Whereas the Shilaif fm. is mainly a “shale oil” play the Diyab fm is exclusively a “shale gas” play. To assess their potential, extensive coring and core analysis has be designed which together with vertical and horizontal well fracking allows to evaluate these resource plays.

Cores from both plays will be exhibited at the 3rd Carbonate Reservoir of the Middle East GTW
