... of oil and gas storage. However, the systematic theoretical of how to build complex fractures in fractured-vuggy carbonate reservoirs is scarce. Facing this situation, this paper presents a method that can improve the accuracy of fracturing effect prediction and optimize fracturing process design...

... resources. Carbonate reservoirs provide a unique set of formation and productivity evaluation related challenges due to the highly variable characteristics of the natural fractures. This work elucidates how production logging data, combined with multiple wireline logs, resulted in resolving water production...

... Abstract Formation evaluation in a gas condensate carbonates reservoir with high temperature and pressure is very challenging: low porosity and gas have an effect on reserve estimation and fluid typing identification. A complex of or state-of-the-art petrophysical studies were implemented...

... Abstract The pre-salt reserves offshore from Santos basin represent a great opportunity and probably the most important recent oil discovery in Brazil. These carbonate reservoirs are currently drilled with various types of drill bits, and have proven to be a challenging environment. Since...

... machine learning techniques have been adopted to categorize electrofacies. In this paper, two supervised machine-learning techniques were implemented to model electrofacies given well logging data for a well in order to predict the distributions in all other wells (classification) in a carbonate reservoir...

... from a heterogeneous carbonate reservoir were used. The data included well log records such; GR, SP, Density, Neutron Porosity, Total Porosity, Resistivity, Induction, Shale Volume, Water Saturation, along with porosity and permeability values from core analysis. These data were integrated and analyzed...

... Abstract To enhance the efficiency of acid stimulation treatments in high-temperature carbonate reservoirs, the industry requires a superior retarded acid system that inherently displays high thermal stability, controlled reaction rate, and acceptable corrosion losses. One of the earliest means...
