Carbonate Cores & Research Services by Kocurek Industries

Indiana LS 70-115mD is from the limestone category with permeability 70-115mD and porosity 17-19%. Carbonate rocks are primarily comprised of limestones. Carbonates typically present good permeability and porosity. Consequently, carbonates are ideal petroleum reservoirs.

Sandstones with Carbonate Cement, Coal Exploration Core

Sandstones occasionally have carbonate mineral cements that cause the rock to react to HCl. Carbonate-cemented sandstones may have any of the sedimentary structures seen in other kinds of sandstone. Two kinds of carbonate cement are common in Carboniferous coal fields: (64X CaCO 3) Calcite-cemented sandstone (64X FeCO 3) Siderite-cemented sandstone

Sandstone vs. carbonate petroleum reservoirs: A global

The two fundamental differences between sandstone and carbonate reservoir rocks are (1) the site of sedi-ment production (allochthonous for sandstones vs. au-tochthonous for carbonates) and (2) the greater chem-ical reactivity of carbonate minerals (Choquette and Pray, 1970; Moore, 2001). The latter difference has

Core Laboratories: A Catalog of Geological and Engineering

Core Lab uses a proven system of classifying reservoir rock types that will provide the link between a "zone of interest" and an analog rock type in the database. Geoscientists and engineers will be able to access the rock property data by rock type, formation, depositional facies, log parameters, petrophysical properties, etc.

Miscible And Immiscible Displacement Studies On Carbonate

Similar displacements were conducted on a composite core made up of the three cores, a homogeneous Berea sandstone and a fractured carbonate core with well-developed inter-crystalline porosity. Each carbonate core is pictured in Plate 1. A qualitative description of the porosity types represented in each core could be summarized as:

EDTA chelating agent/seawater solution as enhanced oil

Apr 01, 2017· Berea sandstone core samples were used in this study. Table 2 lists the properties of the core samples used. The composition of Berea sandstone cores is listed in Table 3. The XRF analysis shows that the Berea sandstone cores contain 2.5 wt% Aluminum, 1.91 wt% ferric, and 0.87 wt% calcium.

Jul 23, 2019· The cores were sourced from Kocurek Industries Ltd at a depth of ~ 183 m, and they are believed to have their origin from Texas, USA. The leopard sandstone and Edward brown carbonate core samples are identified as LPn and EDn, respectively, where n (1–15) is the sample number. The injected chemicals—scale inhibitor (aminotri (methylene

Oct 01, 2020· Core plug A represents the reservoir sandstone in well X-4. 3-D visualization of core plug A in Fig. 10 shows that carbonate minerals make up 16% of core plug total volume. However, mini plug A, which we extracted from the sandstone regions of core plug A, does not sample any of the carbonate minerals in core plug A.

Comparison of scaling relationships of extensional fault

This paper presents a comparative analysis of the thicknesses–displacement relationships of fault cores in non-/low-porous carbonate and porous sandstone reservoirs. Fault thickness data were collected from extensional faults in mainly Cretaceous continental sandstones and Late Cretaceous–Paleogene marine carbonates exposed along the eastern flank of the Suez Rift, Egypt.

Sandstone Wikipedia

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones make up about 20 to 25 percent of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series.
