This paper aims to establish a complete workflow for petrophysical evaluation enhance and quantify hydrocarbon prospect productivity of Shahd SE field, East Ras Qattara concession, Western desert, Egypt. The suggested can, then, be used with the same steps sequences any study. Well logs data from four wells were this present has drilled through three formations: (1) Bahariya Formation, which be...

The volume of shale (Vsh) is a critical parameter in petrophysical analysis that enables the accurate estimation other parameters like effective porosity, saturation and Net-to-Gross. This an important step characterization reservoirs as well valuation hydrocarbon potentials. GR (Gamma Ray), Neutron Density Potassium, Uranium Thorium logs were adopted to estimate analyze Vsh for sand 4 reservoi...

The study aims to implement a high-resolution Extended Elastic Impedance (EEI) inversion estimate the petrophysical properties (e.g., porosity, saturation and volume of shale) from seismic well log data. resolves pitfall basic EEI in inverting below-tuning resolution, dimensionality absolute value are improved by employing stochastic perturbation constrained integrated energy spectra attribute ...

In drilling operation the design of a proper mud weight to avoid any instability’s is important. A low mud weight may cause breakouts around the borehole whereas a high mud weight can fracture the formation. Mud weight design is based on two main factors: the mechanical properties of formations being drilled and the state of in-situ stresses in the field. While drilling in soft formations are t...

primary sedimentary and secondary structural and diagenetic processes are responsible for heterogeneity in carbonate reservoirs and recognition of these factors is very essential subject in modeling these reservoirs. image logs are very useful for identification of structures and small scale sedimentary features. in this research, using image analysis of formation microimager log (fmi) in a dri...

Machine learning is an important part of the data science field. In petrophysics, machine algorithms and applications have been widely approached. this context, Vietnam Petroleum Institute (VPI) has researched deployed several effective prediction models, namely missing log prediction, fracture zone density forecast, etc. As one our solutions, VPI-MLogs a web-based deployment platform which int...

Biyad Formation is mainly made up of clastic sediments that contain substantial amount of proven crude oil in the eastern Yemen. The Byiad clastic is divided into Upper and Lower Biyad clastic units. Several vertical wells have been drilled and penetrated this formation. This study is concerned with the petrophysical evaluation by means of well log data of the Lower Cretaceous rocks at the East...

The onshore Barua Field, near the southeast edge of Lake Maracaibo, is a highly faulted structure producing from the Eocene Pauji and Misoa intervals. This mature field has undergone significant depletion from approximately 30 wells since 1958. A classical, deterministic reservoir characterization study followed by reservoir simulation history matching was conducted. Prior to completing the his...

Abstract Porosity and facies are two main properties of rock which control the reservoir quality have significant role in petroleum exploration production. Well seismic data most prevalent information for characterization. such as logs prepare adequate vertical resolution but leave a large distance between wells. In comparison, three-dimensional can more detailed characterization inter-well spa...
