PhD-thesis: The Evolution of Halite and Solid Bitumen in the Petroleum System of the South Oman Salt Basin

Abstract

The dimension of porosity and permeability controls the quality of a hydrocarbon reservoir rock. Thus, in planning profitable exploration wells it is important to investigate the potential flow path of hydrocarbons (e.g. oil and gas) in the deep subsurface. Hydrocarbon-bearing rocks in our study area are source and reservoir rocks in the same time. These carbonates are drilled in the deep in subsurface (3000 to 5000 m depth) of the South Oman Salt Basin. Both the reservoir rock and the seal (the Ara Salt) belong to a late Proterozoic (Infracambrian) sedimentary basin sequence, called the Ara Formation, which consists of a cyclic sequence of carbonates and thick evaporites.
In the course of geological history since deposition, complex diagenetic processes like dolomitization, dolomite cementation, anhydritization, halite plugging and plugging by solid bitumen changed and/or erased the depositional fabrics and thus the reservoir character. Another interesting stage led to a negative effect for reservoir character, too: the plugging of pore space in the carbonates by solid bitumen.
Both halite and solid bitumen are discontinuously distributed in the Ara carbonate ‘stringers’ and it plays thus a key role for further explorations to map the geometry of the ‘stringer-plumbing’ system and to unravel the plugging mechanisms.
