This paper represents the second part of an integrated study that is focussed on the development and distribution of reservoir bodies and properties in epeiric carbonate systems. It is based on outcrop analogue data from Triassic ‘layer-cake’ carbonates in the South German Basin, which were deposited along an epicontinental, very gently inclined carbonate ramp. The reservoir facies consists of skeletal and oolitic carbonate grainstones (Φmax 23%, Kmax 700 mD), which are organized in a pronounced hierarchy of stratigraphic cycles. Based on outcrops, cores, gamma ray (GR) logs and thin sections, a high-resolution, geocellular 3D facies model was generated, which covers the area of a Middle East giant gas field (25×36 km). The spatial distribution of reservoir properties was systematically investigated on different scales. The lateral distribution of reservoir properties remains in the same order of magnitude for hundreds of metres, within in the same stratigraphic position. However, on a kilometre scale, facies bodies, diagenetic trends and thus reservoir properties show gradual lateral changes. Vertically, in contrast, properties change commonly on a decimetre scale and are largely controlled by stratigraphic cycles. Petrophysical modelling enhanced the understanding of key factors and processes controlling both reservoir quality and quantity.

“…Even though carbonate shoal facies normally represent a typical reservoir rock with favorable porosity (e.g. Ruf & Aigner 2004, Aigner et al 2007, Clerke et al 2008, Casteleyn et al 2010, Casteleyn et al 2011, the samples studied reveal that the diagenetic processes (polyphase) produced a relatively thick sedimentary succession with practically no permeability and very low porosity. Especially the veins and fissures were completely cemented (Mueller et al 2012).…”

Carbonate rocks hosting major proportions of the world's hydrocarbons are characterized by intricate pore systems encompassing different pore scales, shapes and interconnections resulting both from their organic origin as well as different diagenetic processes (e.g. dolomitization, fracturing, leaching, cementation or recrystallization). Apart from interparticle pore space composed of micro-, meso-and macropores, there are also separate and connected vugs (e.g. fractures), influencing important reservoir parameters such as total and effective porosity or permeability. Therefore profound knowledge of the impact of pore types and interconnections on log data has to be acquired in order to ensure accurate evaluation with respect to porosity. Particularly regarding electrical properties and Archie's relationship -having been established for clean rocks and connecting formation resistivity factor F and total porosity -a special modification in carbonates with regard to their complex pore systems is required. Thus a petrophysical database including resistivity and porosity data of a range of carbonate rocks with various pore types (interparticle and vuggy, both separate and connected) needs to be established. The analysis of the database leads to a modified Archie relationship taking account of the effect of separate vugs and fractures on electrical current flow. This novel modification allows a first step towards porosity partitioning in a water-saturated carbonate formation into proportions that are isolated or accessible for electrical current flow and thus also for hydraulic fluid flow -one of the most important features with regard to producibility and recovery. A set of log data from a sample well is presented to apply and test this new approach on carbonates with challenging pore space characteristics. This novel modification of Archie's equation may prove beneficial to fields of research related to reservoir properties in complex carbonate reservoirs. TX 75083-3836, U.S.A., fax +1-972-952-9435
