Geomechanical Sanding Prediction in Oil Fields by Wellbore Stability Charts

Sand production is a universally encountered issue during the exploration of unconsolidated sandstone reservoirs particularly during production. The production of sand particles with the reservoir fluids depends on the stress around a wellbore and the properties of the reservoir rocks and fluids. Therefore, it is crucial to predict under what production conditions sanding will occur and when sa...

Generalized Possibility and Necessity Measures on Fields of Sets

We give a generalization of possibility and necessity measures: their domains are extended towards fields of sets, and their codomains towards arbitrary complete lattices. In this way, these measures can be associated with (Q,≤)-fuzzy sets, where (Q,≤) is at least a poset. An important inconsistency problem, intricately linked with this association, is solved. It is argued that order lies at th...

A New Cementation Factor Correlation in Carbonate Parts of Oil Fields in South-West Iran

Petrophysical parameters such as porosity, water and oil saturations, formation resistivity factor, etc. describe the storage capability of the porous media or the capacity of rocks to hold fluids. The modified Archie’s equation . / . , also called the saturation equation, is used to determine the water saturation. Archie’s parameters, namely , , and , are sometimes assumed constant to simp...

Adaptation of Pseudomonas aeruginosa in Kansas oil fields for use in tertiary oil recovery

Over half of the oil reservoirs in the United States are considered “empty” although they still contain approximately 50% of their potential yield (Exxon Corporation, 1983). Pseudomonas aeruginosa produces a rhamnolipid biosurfactant extracellularly that can drive this trapped oil from crevices into openings that can be easily pumped. This tertiary method of oil recovery is currently being used...
