Siliciclastic Reservoirs of the Middle East
23 – 25 March | Kuwait City, Kuwait
Sandstone is the dominant reservoir lithology in the Cambrian to Lower Permian section of the Arabian Plate. Thick clastic sections are also developed in the upper-Lower to Middle Cretaceous and as well in Neogene aged rocks. During the Pre-Cambrian to the Mid-Permian, the Middle East Region was principally located in mid to high southern latitudes in cold-dry to cold-wet climatic belts with a predominance of clastic sedimentation and only sporadic carbonate deposition. These sandstone reservoirs are important productive intervals in many of the Middle East countries but have often been overshadowed by the younger carbonate plays. Additionally, productive sandstone reservoirs in the Mid to Late Triassic and the Lower to Middle Cretaceous contain significant quantities of hydrocarbons which are under development and still retain exploration opportunities.
Significant advances over recent years in reservoir characterization and modeling of clastic reservoirs emphasize the need for understanding the lateral and vertical facies changes within the sandstone reservoirs. Due to the large area that these reservoirs cover, regional understanding of changes in facies could assist in their better understanding. In addition to facies and depositional environments, the sequence stratigraphic make-up of these reservoirs is critical for both understanding the best field development concepts in a given area as well as in identification of future exploration areas.
In the workshop, the case histories will illustrate regional depositional and sequence stratigraphic settings and as well as examples of field scale reservoir characterization. Key learnings will include the spatial distribution of clastic reservoir facies across the Middle East Region as well as key issues related to hydrocarbon production and field development both from a technical to management decision making view.
As part of the workshop, a Core Workshop will be included throughout the duration of the workshop. Exact details on Core display will follow soon.

The technical program committee is working diligently to put together a top quality program for this workshop. A detailed overview of the technical program to follow soon. The following sessions topics will be covered:
- Session 1: Clastic Systems
- Session 2: Paleozoic Reservoirs
- Session 3: Mesozoic Reservoirs
- Session 4: Tertiary Reservoirs/Global Case Histories
- A field trip is scheduled as part of the program on the last day of the workshop
The workshop is an opportunity for attendees to receive up-to-date knowledge about clastic reservoir characterization, exposure to regional case studies and to be introduced to state of the art-technologies utilized to explore and develop these important reservoirs. It is an opportunity to network and share experiences. The participants will receive a summary of the breakout sessions and discussions, lessons learned and a USB with abstracts for papers presented in the workshop.
Geological Field Excursion, Wednesday 23rd of March 2015
As part of the workshop program, a geological field excursion has been planned and will take the participants to the following two locations:
- Exposures at Enjefa Beach, Salwa District, Kuwait
- Exposures at Jal Az-Zor, North Kuwait
Field Area A: The Enjefa Beach lies on the northwestern margin of the Arabian Gulf in Kuwait across the district of Salwa. Thin, about 10-12 feet thick, mixed siliciclastic-carbonate Holocene rocks are exposed along the North-South beach axis over about half a kilometer distance. Part of the exposure makes beach side cliff and the rest covers the present day intertidal area. The participants will observe:
- Coastal microenvironments and their products, including;
- Beach to foreshore facies
- Tidal channel facies
- Shallow channel or ebb tidal delta deposits
- Coastal sand flat deposits with Ophiomorpha and related burrows network
- Lateral and vertical stacking pattern of these facies and its importance.
- Subaerial unconformity at top of the exposure.
- Ridge and runnel physiography developed by wave and current erosion in the present day intertidal area.
After making detailed observations, the participants are expected to indulge in discussions on the field deductions related to the origin of these rocks, their age assignment and importance of these ages with respect to the formation of the Gulf, relative sea level, and present day state of the Gulf.
Field Area B: This geological field excursion will take the participants to North Kuwait to Jal Az-Zor area where an escarpment sharply rises above from the sea level. It underlies equivalent to Lower Fars Formation (Miocene age) or younger rocks. The participants will observe:
- Physiography as it relates to rock type; peneplain versus cliff.
- Cyclic sedimentation with dominance of coarsening upward sequences. Most of the sequences consist of loosely consolidated and easily erodible variegated colour mudstone which passes upwards into calcareous sandstone and or sandy limestone.
- Sedimentary facies and their vertical and lateral relatioships.
- Environments of deposition (shallow marine, delta plain, and fluvial).
- Implications for subsurface analoguing such as; seal versus reservoir facies, lateral continuity or discontinuity of reservoir facies and their paleoenvironmental control, stratigraphic compartmentalization and development of different reservoirs with its own pressures within the same formation.
- 08.00 – 08.30 hours – an overview of the field excursion followed by departure to Field Area A from the Jumeirah Hotel
- 09.00 – 10.00 hours – time at Field Area A
- 10.00 hours – departure to Field Area B
- 11.00 – 13.00 hours – time at Field Area B (lunch boxes will be provided)
- 14.00 hours return at the Jumeirah Hotel
What to bring:
- Hiking Shoes
- Sun hat
- Jacket for potential cooler areas
Please note that lunch, water and transportation will be provided and the field trip costs are included in the workshop registration fees.
