The porosity and permeability of sandstone and carbonate reservoirs (known as reservoir
quality) are essential inputs for successful oil and gas resource exploration and exploitation …

Assessment of reservoir and fracture parameters is necessary to optimize oil production,
especially in heterogeneous reservoirs. Core and image logs are regarded as two of the …

The introduction reviews topics relevant to the fundamental controls on fluid flow in
carbonate reservoirs and to the prediction of reservoir performance. The review provides …

There is ongoing debate on whether stylolites act as barriers, conduits, or play no role in
fluid transport. This problem can be tackled by examining the spatial and temporal …

Obtaining a fit-for-purpose rock-type classification that adequately incorporates the key
depositional and diagenetic heterogeneities is a prime challenge for carbonate reservoirs …

Abstract The Upper Jurassic (Kimmeridgian) Arab-D reservoir of the Arab Formation in the
Arabian Peninsula is considered to be the largest hydrocarbon carbonate reservoir in the …

Stylolites are rough surfaces that form by pressure solution, and present variable geometries
and spatial distributions. Despite being ubiquitous in carbonate rocks and potentially …

Microporous carbonates contain perhaps 50% of the oil left behind in current projects in the
giant carbonate fields in the Middle East and elsewhere. Pore geometry, connectivity, and …

Solid bitumen in calcite veins in Natih limestone on the southern flank of the Jebel Akhdar
Anticline provide evidence for at least two previously unrecognized petroleum migration …

Core samples from seven wells in Lower Cretaceous limestones of the Upper Shu'aiba
Member were characterized by conventional core analyses, petrography, bulk chemistry and …
