Abstract: Methods and systems are presented in this disclosure for evaluation of formation properties (e.g., permeability, saturation) based on interpretation of data obtained by production logging tools (PLTs). Based on the PLT data, a production rate for a component (e.g., production fluid) produced by a wellbore can be determined, and a distribution of a property of the component can be initialized along a length of the wellbore. A simulated production rate for the component can be calculated, based on the distribution of the property using a simulator for the wellbore. The distribution of the property can be iteratively adjusted based on the production rate and the simulated production rate, until convergence of the distribution for two consecutive iterations is achieved. A reservoir formation model used for operating the wellbore can be updated based on the adjusted distribution of the property of the component.

Abstract: Selecting hydrocarbon wells for well testing. The selecting may include identifying hydrocarbon wells whose last well test took place prior to a predetermined date; identifying hydrocarbon wells with a parameter that exceeds a predetermined threshold; and selecting a predetermined number of hydrocarbon wells from the wells identified.

Abstract: A method and non-transitory program carrier device tangibly carrying computer executable instructions for adjusting downhole valve settings in order to optimize oil recovery and reduce water production from a well. The method and non-transitory program carrier device are particularly advantageous in wells with intelligent completions that are often referred to as smart wells. In the oil and gas industry, an Internal Control Valve (ICV) is an important tool for both reactive and proactive approaches to adjust ICV settings to improve oil recovery.
