Abstract: Systems and methods for controlling extraction of landfill gas from a landfill via a gas extraction system are provided herein. According to some aspects of the technology, there is provided site-level control methods for globally controlling one or more wells based on one or more characteristics of aggregate landfill gas collected from a plurality of wells at a gas output. According to some aspects of the technology, there is provided well-level control methods for locally controlling a first well based on or more characteristics of landfill gas collected from the first well. According to further aspects of the technology, there is provided hybrid control methods for making adjustments to a respective well based on both site-level and well-level control methods.

Abstract: A gas input switching device (also referred to as a “multipoint system”) receives gas samples from multiple gas sources (e.g., gas wells or other gas source) for testing using a gas analyzer (e.g., a laser sensor). Advantageously, using the multipoint system discussed herein, multiple individual gas sources may be analyzed by a single gas analyzer by alternating input to the gas analyzer between the multiple gas lines, such as according to a multipoint switching algorithm.

Abstract: Apparatus and methods are provided relating to bottom hole assemblies (BHA) for the isolation and treatment of selected zones using an uphole and a downhole sealing element. The BHA also includes a location and shifting mechanism for locating, engaging and actuating features in a wellbore. The BHA provides for the selective location and actuation of downhole features such as flow valves, precise introduction of fluid, and real-time monitoring of downhole conditions. Methods of deploying a BHA and treating an area of interest using the BHA includes engaging sealing elements using hydraulic pressure.

Abstract: A technique for providing a fluid conduit between a main bore and a substantially non-producing region of a fracture at a horizontal section of the bore. The technique includes forming a micro-tunnel from a location of the bore adjacent the fracture. The micro-tunnel may be directed at the non-producing region with a angled deflector or in a steerable manner. Additionally, the well may be configured with micro-tunneling at the outset or retrofitted with micro-tunnels as a manner of restoring production.

Abstract: Systems and method for injection a chemical into a wellbore. A chemical injection system may comprise a first valve, a chemical line, a pilot line, an injection line, and a backflow prevention valve disposable in the injection line. A production fluid recovery system may comprise a chemical injection system, a first valve, a pilot line, an injection line, a backflow prevention valve, a production tree, a wellhead, and production tubing. A method for actuating a valve in a chemical injection system may comprise pushing a fluid into a chemical line, pressurizing a pilot line to open a first valve, pushing the fluid through the first valve, increasing pressure in the pilot line to open a second valve, pushing the fluid through the second valve, pushing the fluid through a chemical line, and injecting fluid into a wellbore from the chemical line.
