Hydrocarbon gas production system

A method of producing hydrocarbons from a hydrocarbon reservoir, the method comprising:

• obtaining, by a well production monitoring system, well production data for wells in a hydrocarbon reservoir, the well production data comprising measured hydrocarbon production of the wells in a first production region and wells in a second production region;
• sensing, by production sensors of a gas production monitoring system, gas characteristics of hydrocarbons produced by the wells, each of the gas production sensors sensing a characteristic of gas produced by one or more of the wells and being associated with a first production region or a second production region,
• generating, by the gas production monitoring system, gas production data comprising measurements of gas characteristics sensed by the gas production sensors, each of the measurements by a gas production sensor being associated with a production region of the gas production sensor and a time of measurement, wherein the gas production sensors comprise carbon dioxide (CO2) content type sensors, hydrogen sulfide (H2S) content type sensors, and total dissolved gas content type sensors;
• receiving, by way of a user interface of a production monitoring system, user selection of modeling parameters comprising a selected region and a selected time period;
• and
• generating, in response to receiving the selection of the modeling parameters, a set of well performance data comprising:
• well production data comprising a subset of the production data for a subset of the wells (i) in the selected region and (ii) measured in the selected time period;
• and
• gas production data comprising gas characteristics sensed by gas production sensors (i) associated with the selected region and (ii) measured in the selected time period;
• generating, by a production modeling system and based on the set of well performance data, a model of the performance of the subset of the wells located in the selected region;
• identifying, by a production modeling system and based on the model, a first well having the greatest amount of sales gas contributions to production of the hydrocarbon reservoir production system and a second well having the least amount of sales gas contributions to production of the hydrocarbon reservoir production system;
• regulating, by a production operations system and based on simulation of the model, operation of one or more of the wells in the selected region, wherein regulating operation of one or more of the wells located in the selected region comprises:
• determining, based on application of predicted well production data for the subset of the wells located in the selected region to the validated model, sets of predicted sales gas characteristics for the subset of the wells located in the selected region;
• assessing the sales gas characteristics to determine a select one of the sets of predicted sales gas characteristics that satisfies a sales gas criteria;
• determining, based on determined select one of the sets of predicted sales gas characteristics, target production flowrates for the wells in the selected region and
• operating the wells in the selected region in accordance with the target production flowrates by controlling valves associated with the wells.
