    Abstract: An estimated gas leak flow rate can be determined using a teaching set of concentration profiles, a regression model implemented by a machine-learning subsystem, and a subset of attributes measured within an environment. The teaching set of concentration profiles can include gas flow rates associated with relevant attributes. The regression model can be transformed into a gas leak flow regression model via the machine-learning subsystem using the teaching set. The subset of attributes measured within the environment can be applied to the gas leak flow regression model to determine other attributes absent from the subset of attributes and an estimated gas flow rate for the environment. A gas leak attenuation action can be performed in response to the estimated gas flow rate.

    Abstract: The disclosed embodiments include a method, apparatus, and computer program product for improving production of an oil well. For example, one disclosed embodiment includes a system that includes at least one processor and at least one memory coupled to the at least one processor and storing instructions that when executed by the at least one processor performs operations for generating a model of a wellbore in a wellbore simulator. The at least one processor further executes an algorithm that determines optimal parameters for inflow control devices (ICD) along a horizontal portion of the wellbore. The determined optimal parameters of the inflow control devices would yield a substantially uniform approach of at least one of water and gas along the horizontal portion of the wellbore.

    Abstract: Method of determining drilling fluid density with contaminants fluid includes positioning one or more sensors within a wellbore to measure one or more characteristics of one or more individual components of a fluid within the wellbore. A gas solubility value and a volume formation factor for the one or more individual components of the fluid can be obtained based on the measured one or more characteristics. A formation gas modified volume of the drilling fluid can be calculated using the volume formation factor and a volume fraction for each of the one or more individual components. A total mass of the drilling fluid can be determined using the mass of the one or more individual components and a mass of dissolved gas, and a formation gas modified density of the drilling fluid can be determined based on the total mass and the formation gas modified volume.
