An injection fluid is pumped down along an interior of the tubing string and out through the plurality of flow control devices for entry into the surrounding formation. Based on a function of this injection flow, the flow areas of the flow control devices are adjusted to improve the subsequent distribution of inflowing fluids. The injection and the subsequent adjustment of flow areas as a function of the injection flow through each flow control device may be repeated for continued improvement, e.g. continued optimization, of the inflow distribution.

  • Patent number: 9501851
    Abstract: Various systems and methods are provided that display various graphs in an interactive user interface in substantially real-time in response to input from a user in order to determine information related to measured data points and provide the determined information to the user in the interactive user interface. For example, a computing device may be configured to retrieve data from one or more databases and generate one or more interactive user interfaces. The one or more interactive user interfaces may display the retrieved data in one or more graphs, such as time-series or scatterplots. The user interface may be interactive in that a user may manipulate one graph, which causes an identical or nearly identical manipulation of another displayed graph in real-time. The manipulations may occur even if the displayed graphs include data across different time ranges.

  • Patent number: 9200509
    Abstract: The present invention discloses an improved system for measurement of the liquid flow rate and totalized liquid production of a producing well. In the method of the present invention, liquid production rate in a pumping well is determined by calculation based upon wellbore geometry and continuously monitoring the depth of the fluid level within the wellbore. It is applicable to any pump lifted well where it is possible to shut the pump off periodically. Accuracy is enhanced with this method by properly accounting for pump leakage and where pump leakage is either known or can be estimated within reasonable limits or where it is measured during the pump shut off cycle.

  • Patent number: 9151868
    Abstract: An interactive system and method of operating the system to define and evaluate a model of a hydrocarbon reservoir. The reservoir model is defined from extrinsic information such as seismic surveys, well logs, and the like, and is based on elements of formation regions, connections among the regions, wells, and perforations. A boundary-element method is used to determine pressure interference responses, corresponding to the pressure at a perforation in response to a single perforation producing fluid at a unit flow rate. These pressure interference responses are then convolved with measured well flow rates obtained during production to arrive at estimates of the wellbore pressure at one or more wells of interest. The estimated wellbore pressure can be compared with downhole pressure measurements to validate the reservoir model, or to provoke the user into modifying the model and repeating the evaluation of the model.
