... and high downhole temperature. Reservoir characterization is indispensable in the development of this Cretaceous structural fractured tight sandstone reservoir formation. Fluid identification is a key tool used to locate the sweet spot with high producibility for further development. Resistivity...

... the current industry needs very well, as it is reliable, maximises return and can be easily integrated into the development strategy of any CSG reservoir. The novelty of the methodology relies on the qualitative identification of permeability and gas saturation to capture reservoir heterogeneity...

... Abstract Identification of an optimal field development plan is one of the most critical decisions for oil asset management. In the new norm of low oil prices, this assumes even more relevance for mature oilfields to maximize overall recovery. In greenfield developments and oilfields in early...

As a dimension reduction statistical method, the purpose of PCA is to use relatively fewer indicators instead of more factors to carry out the comprehensive evaluation...

... cards evaluation has led to the identification of several mechanical pump issues such as a traveling valve and standing valve leak that directly impact production. One step of the traditional process to identification of rod pump failure is based on a manual pump card shape analysis performed...

... Abstract A new quantitative model of water channeling identification in unconsolidated sandstone reservoir is presented that uses the hierarchical analysis and grey correlation method as its basis for calculations. By analyzing the influential factors of water channeling, seven static factors...

... Abstract The automation of lithology identification based on natural gamma, resistivity, neutron density and other well logging data is an important step to perform intelligent drilling/geo-steering. The current identification of lithology normally is based on the statistical results...
