Ichnology as a tool in carbonate reservoir characterization: A case

Ichnological studies have typically played only a minor role in the sedimentological analysis of carbonate reservoirs (e.g. Goldring et al., 2005; Pemberton and Gingras, 2005), although the study of ichnofabrics has long been used in siliciclastic deposits (Taylor and Goldring, 1993; McIlroy, 2004), proving to be a valuable tool for the

Claystone vs. Mudstone: Generalization: The terms "claystone" and "mudstone" are sometimes used interchangeably. However, mudstone is a broader term that includes rocks with a mix of clay, silt, and other fine-grained particles. Claystone is a specific type of mudstone dominated by clay-sized particles.

6 FAQs about [Can mudstone be used as a reservoir ]

How to evaluate mudstone reservoirs in different depth?

It is a fast and effective method to qualitatively evaluate the relative gas content of mudstone reservoir in different depth by using resistivity and neutron or uranium and neutron overlap. The method is to find a depth that makes its overlapping area relatively minimum.

What is the gas reservoir space in mudstone?

The gas reservoir space in mudstone is mainly composed of mineral matrix pore and micro−fracture. Figure 6 shows the SEM images of the intergranular pore, intragranular pore and micro-fracture in the core samples of the A2 well mudstone reservoir.

What is mudstone used for?

Abstract. Mudstone is the most abundant sedimentary rock and variously acts as sources, seals, and shale gas reservoirs in petroleum systems. Many

Are mudstone reservoirs fracturable?

The average proportion of these minerals is 47.8% of clay minerals, 38.9% of quartzite, 2.9% of feldspar, 2.6% of calcite, 2.7% of dolomite and 5.1% of pyrite, respectively (Fig. 4 (b)). Brittle minerals include quartz, calcite and dolomite, the sum of which is 44.2%. This indicates that mudstone reservoirs are fracturable.

What type of rock is mudstone?

Mudstone is a type of sedimentary rock that consists of a variety of types, including siltstone, claystone, and mixtures of the two. It can form thick intervals in deepwater settings and is important as it forms boundaries, seals, and baffles for reservoirs. You might find these chapters and articles relevant to this topic. Jon R. Rotzien, ...

Does mudstone reservoir have a high thermal evolution of organic matter?

The data from the 28 mudstone core samples of the Shanxi Formation show that the R o ranges from 3.0% to 3.8% and the average is 3.5% (Fig. 4 (c)), which proves that the mudstone reservoir has a high thermal evolution of organic matter. To the extent, the kerogen release is almost entirely gas.
