A plunger having a generally hollow interior between an open upper end of the plunger and a closed bottom end of the plunger. One or more orifices extend through a sidewall of the plunger near the closed bottom surface. The orifices fluidly connect the hollow interior of the plunger with the tubing below the plunger when the plunger is in use. The orifices allow for a transfer of gas from the well bottom into the liquid load above the plunger during plunger ascent. The orifices also allow liquids to pass through the plunger during plunger descent.

Graphical user interfaces for abating emissions of gaseous byproducts at hydrocarbon assets are described herein. In one example, a system can receive measurements of gaseous byproduct emissions from sites. The system can execute a classification module to distribute the measurements among various types of equipment. The system can then determine emissions estimates associated with the various types of equipment based on the measurements assigned to each type of equipment. Thereafter, the system can receive a user input that includes a list of types of equipment at a target site. The system can generate a total emissions estimate for each type of equipment in the list based on the emissions estimates. The system can then generate a graphical user interface providing the total emissions estimate for each type of equipment in the list to a user, which may help the user abate such emissions.

Described herein are embodiments of apparatuses and methods that include an improved double sleeve plunger. In an exemplary embodiment, the improved double sleeve plunger includes an outer sleeve, and inner sleeve, and a clutch, whereby the clutch retards movement of the inner sleeve relative to the outer sleeve between and open and closed position of the plunger.

A system and method for removing water from mine areas. In one embodiment, one or more directionally drilled dewatering wells are drilled into the geologic formation such that at least a portion of the dewatering well is positioned underneath the mine. In one embodiment, one or more of the dewatering wells may originate outside the perimeter of the mine so as not to interfere with mine operations. In one embodiment, a hydrogeologic assessment along with mine dewatering requirements may be used to generate a mine dewatering plan. In one embodiment, a hydrogeologic assessment along with a determination of the dewatering requirements of the mine and surrounding areas may be used to create a mine dewatering plan. In one embodiment, the mine dewatering plan provides design information pertaining to each dewatering well.

A system for producing Methane from a Methane Hydrate formation including a completion that is disposed through a Methane Hydrate formation. An inlet of the completion disposed in the Methane Hydrate formation; and a drain for water located in a direction proximate a direction of gravity relative to the Methane Hydrate formation and gravitationally beneath the Methane Hydrate formation. A method for producing methane from a Methane Hydrate formation

An unloading plunger having an internal chamber to hold compressed gas and a timer-operated valve to release the compressed gas through a gas jetting port as a jetting force for ascent of the unloading plunger in a wellbore to unload liquid from a well. The ascending of the unloading plunger may be via a combined motive force of wellbore pressure provided by formation pressure plus the jetting force provided by ejecting the compressed gas from the unloading plunger.

In some implementations, a method involves determining a level of accumulation of a hydrocarbon-water emulsion in an annulus of a wellbore. The method further involves based on the level of accumulation, determining an operating setting of a hydrocarbon-water separator and operating the hydrocarbon-water separator at the operating setting, where the hydrocarbon-water separator separates the hydrocarbon-water emulsion into water and a hydrocarbon fluid. Further, the method involves activating, in response to a first sensor detecting a first water level in the annulus, a pump that pumps the water from the annulus into a water zone below the wellbore. Yet further, the method involves deactivating the pump in response to a second sensor detecting a second water level in the annulus, where the second sensor is located below the first sensor.

Described herein are embodiments of systems and apparatuses that include a dart and/or a clutch for a dart plunger. In an exemplary embodiment, the dart plunger includes a dart adapted to move between a first position and a second position and also between a maximum closed position and a minimum closed position. Varying diameters of the dart enable the clutch to variably retard movement of the dart between its first, second, maximum, and minimum positions.

A method of removing wellbore water from a production wellbore includes determining a production flow rate. The method also includes determining a target production flow rate of the production fluid and comparing the production flow rate to a flow rate threshold associated with the target production flow rate. The method also includes determining, based on a result of comparing the production flow rate to the flow rate threshold, that the production flow rate satisfies the threshold. The method also includes activating a fluid moving device fluidly coupled to a wellbore string extending from a terranean surface to the water to inject, into the water, at least one of i) a surfactant, ii) a gas, or iii) a foaming agent, allowing the water and the production fluid to emulsify together and thereby allowing a mixture of water and production fluid to flow to the terranean surface of the wellbore.

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.
