A comparison of rock physics models for fluid substitution in carbonate rocks
TLDR
In this paper, two additional models, the differential effective medium (DEM) model and the self-consistent (SC) model, have been evaluated for several carbonates samples.Abstract:
Rock physics models play a crucial role in seismic reservoir characterisation studies. The optimal rock physics model for a sandstone reservoir might be significantly different from that of a carbonate reservoir. There are several theories that compare the elastic properties of dry and saturated rocks. These models have mainly been explained by poroelastic theoriesoreffectivemediumtheories.TheGassmann'smodelwhichiscommonlyusedinpetroleumrockphysicsissuitable for rocks with spherical and interconnected pores at low frequencies. These assumptions do not necessarily meet the conditions of carbonate rocks. In this work, two additional models, the differential effective medium (DEM) model and the self-consistent(SC)modelhavebeenexaminedforseveralcarbonatesamples.Ultrasonic30carbonateand5sandstonecore samples from an oilfield in south-west Iran were measured in the laboratory. The results show that the DEM model gives the best compatibility with the dense and low porous carbonate samples. These results are confirmed by well log data from the same area.read more

An experimental study of solid matrix weakening in water-saturated Savonnières limestone
TL;DR: In this article, the authors performed precise indentation tests on Savonnieres limestone at a micro-scale level under dry, distilled water, and n−Decane saturated conditions, and found that mainly the ooid cortices, peloid nuclei and prismatic intergranular cement are affected by water flooding.
