Webinar: Salt structure and strain development in the eastern Mediterranean, and Kurdistan Oil Field trapping mechanisms

13.00-14.00

Sian Lianne Evans (UiO) : Salt structure and strain development in the eastern Mediterranean: an analogue for early-stage salt basin evolution and implications for CCS

Summary:

The Messinian salt in the eastern Mediterranean is a young and relatively undeformed salt giant. This allows us to gain valuable insights into the early stages of salt basin evolution, which are often overprinted and poorly imaged in more mature salt basins. In this presentation we look at the partitioning of intra-salt and supra-salt strain in response to gravitational drivers, with implications for velocity modelling and drilling through thick salt. Finally, we compare this to the mature salt tectonics of the Norwegian-Danish Basin and its potential for CO2 storage.

Nils Bang (DNO): Kurdistan Oil Field trapping mechanisms. A story of dynamic seals, breached seals and oil seeps. Quantifying fault sealing capacity with examples from the Tawke Field, Kurdistan, Iraq

Kurdistan Oil Field Trapping Mechanisms.
A story of dynamic seals, breached seals and oil seeps.
Quantifying fault sealing capacity with examples from the Tawke Field, Kurdistan, Iraq

Summary:

The Tawke Field is situated at the northeast margin of the Arabian Shield in the northernmost extension of the Zagros Mountain Chain, close to the triple point of the Turkish and Iranian plates. The tectonic history covers two episodes of rifting in the Triassic and the Upper Jurassic to Lower Cretaceous. This is followed by the formation of the Zagros Mountain Chain that began in the late Campanian and finished in the Pliocene.

The Tawke Oil Field produces from two fractured carbonate reservoirs of Cretaceous and Oligocene age. A world class oil seep is situated at the top of the structure.

This presentation will go through an introduction of the development of the Tawke structure and will discuss the trapping mechanisms for the oil field. 

The hydrocarbon columns of the two reservoirs are both controlled by dynamic sealing faults. The capacity of the fault seals will be discussed and quantified together with the migration of the hydrocarbons and the origin of the oil seeps.
