    • A system for producing hydrocarbons from a subterranean well including a wellbore extending from a surface into a subterranean formation, the system including a wellhead disposed at the surface. In addition, the system includes a production tree coupled to the wellhead. Further, the system includes a casing coupled to the wellhead and extending into the wellbore. Still further, the system includes a first plurality of production tubing strings extending into the casing from the wellhead to a first production zone. Each of the first plurality of production tubing strings is configured to provide a fluid flow path for gases from the first production zone. The production tree is configured to selectively and independently control fluid flow through each of the first plurality of production tubing strings.
    • 一种用于从包括从表面延伸到地下地层的井眼的地下井产生烃的系统,所述系统包括设置在所述表面处的井口。 此外,该系统包括耦合到井口的生产树。 此外,该系统包括联接到井口并延伸到井筒中的壳体。 此外,该系统包括从井口向第一生产区域延伸到壳体中的第一多个生产管柱。 第一多个生产管柱中的每一个被配置成为来自第一生产区的气体提供流体流动路径。 生产树构造成选择性地和独立地控制通过第一多个生产油管柱中的每一个的流体流动。

    • A method for producing gas from a well including a wellbore extending from a surface into a subterranean formation, wherein the well also produces liquid, the method including: (a) producing gas from a production zone in the subterranean formation through an annulus extending within the wellbore at a first velocity that is greater than a critical velocity, and (b) pumping liquid through a liquid tubing string after (a) to reduce a level of the liquid within the wellbore. The method also includes: (c) shutting in the annulus after (a) after the first velocity decreases below the critical velocity, wherein the annulus has a first cross-sectional area and the first production string has a second cross-sectional area that is less than the first cross-sectional area, and (d) producing gas from the production zone through the first production tubing string after (c) at a second velocity being greater than the critical velocity.
