Ternary Rock Typing: A Novel Solution to Multi-Scale Multi-Discipline Rock Typing for Carbonate Rocks [PDF]

81st EAGE Conference and Exhibition 2019, 2019
Summary Carbonate reservoir rocks exhibit property alterations due to depositional texture, diagenesis and fracturing. Superposition of these processes results in a heterogeneous rock and a complex pore system. The workflow proposed addresses the independent ternary interrelationships between porosity, permeability and irreducible water saturation in ...

An improved rock typing method for tight sandstone based on new rock typing indexes and the weighted fuzzy kNN algorithm

Journal of Petroleum Science and Engineering, 2022
Petrophysical rock typing is a very important problem in flow unit interpretation and reservoir characterization. Unlike the sandstone, the presence of numerous nanopores in tight sandstone can cause strong gas and liquid non-linear flow.

A Type Curve for Carbonates Rock Typing

International Petroleum Technology Conference, 2013
Abstract Rock typing for heterogeneous carbonates is still a standing problem. The present work was directed to investigating the relationship between microscopic geological characteristics of carbonates and architecture of the pore systems in the effort to develop a better method for carbonates rock typing.

The effect of rock crusher and rock type on the aggregate shape

Construction and Building Materials, 2020
Abstract Aggregate shape characteristics play an important role in the performance of the aggregate materials. The type of crusher and rock may play an important role in aggregate shape characteristics. The aim of this study is to investigate the effect of two types of crusher on the shape characteristics of different rock aggregate.
