... Abstract The accuracy and precision of well rates are paramount in reservoir management, well performance surveillance, flow assurance, and any third party processing arrangements. Rate allocation is traditionally based on well rate tests and downtime. This method is usually time-consuming...

... for determining the rate and the thermal conductivity coefficient are derived. The comparison with the "exact" values obtained from numerical method shows high accuracy of the proposed formulae, allowing recommending them for practical estimates. Further in the text, the formulae will be used as a first...

... Abstract Most of the existing correlations for estimating gas viscosity were developed in mid 60's and 70's of the last century. Limited number of data was used to develop them and their accuracies are questionable. Predicting accurate gas viscosity is extremely important in the oil and gas...

... with better accuracy. This study employs hybrid of both approaches to improve the prediction of permeability of a very heterogeneous carbonate reservoir. This study was conducted in three main phases. In the initial phase, reservoir layers were grouped considering data availability and layers’ lithology...
