Permeability Estimation Using an Integration of Multi-Resolution Graph-based Clustering and Rock Typing Methods in an Iranian Carbonate Reservoir [PDF]

Journal of Petroleum Science and Technology, 2021
Rock typing has been utilized in numerous studies where it has been proven to be a powerful tool  for determining rock properties and estimating unknown parameters such as permeability. It can be performed based on routine core analysis (RCAL) or special

Deep convolutions for in-depth automated rock typing [PDF]

Computers & Geosciences, 2020
The description of rocks is one of the most time-consuming tasks in the everyday work of a geologist, especially when very accurate description is required. We here present a method that reduces the time needed for accurate description of rocks, enabling the geologist to work more efficiently.

Water saturation modeling using modified J-function constrained by rock typing method in bioclastic limestone

Oil & Gas Science and Technology, 2020
Combining both geological and petrophysical properties, a reliable rock typing scheme can be achieved. Two steps are included in rock typing. Step 1: rocks are classified into lithofacies based on core observations and thin sections; Step 2: lithofacies ...

An Improved Method of Clay-Induced Rock Typing Derived from Log Data in Modelling Low Salinity Water Injection: A Case Study on an Oil Field in Indonesia

Energies, 2022
Low salinity water injection (LSWI) is an emerging way to improve waterflood performance through chemical processes. The presence of clay minerals is one of the required parameters to successfully implement LSWI in sandstone formations.

Effect of overburden pressure on determination of reservoir rock types using RQI/FZI, FZI* and Winland methods in carbonate rocks

Petroleum Science, 2019
Rock typing is an important tool in evaluation and performance prediction of reservoirs. Different techniques such as flow zone indicator (FZI), FZI* and Winland methods are used to categorize reservoir rocks into distinct rock types.
