Abstract: Methods for cleaning wellbore perforation clusters and reservoir fractures include extending a conduit into a wellbore until the conduit reaches a measured depth deeper than a designated perforation cluster, moving the conduit back and forth between the measured depth and a shallower measured depth, and dispensing different fluids into the wellbore via the conduit during respectively different cycles of the back and forth motion. The fluids may be liquid and/or gas. The conduit is dimensionally configured and arranged within the wellbore such that a passageway exists in the wellbore exterior to the conduit. The methods include closing the passageway prior to, at the same time or subsequent to introducing a gas-containing fluid into the wellbore and continuing to dispense the gas-containing fluid into the wellbore after closing the passageway. Storage mediums having program instructions which are executable by a processor for performing any steps of the methods are also provided.

Abstract: A wellhead system includes a sequence valve in fluid communication with a wellhead device having a first hydraulic actuation device and a second hydraulic actuation device. The sequence valve includes a valve element configured to direct flow to the first hydraulic actuation device in a closed position and to direct flow to the second hydraulic actuation device in an open position. The sequence valve can actuate the second hydraulic actuation device after fully actuating the first hydraulic actuation device. Because the sequence valve can control the order of actuation of the actuation devices, the sequence valve can simplify the operation of the wellhead device and prevent incomplete or improper actuation of the wellhead device. The sequence valve can be utilized in remote and high pressure applications. Because of this, the sequence valve can provide reliable operation in various configurations.

Abstract: A method for directionally drilling a portion of a borehole, comprising utilizing a drilling system associated with a drill string and a drill bit; rotating the drill string and placing an axial load on the drill string causing the drill string to move into compression; and stopping rotation of the drill string and with the drill string in compression, drilling a portion of the portion of the borehole while actively managing a toolface angle of the drill bit.

Abstract: A delivery system for feeding particulate matter to a target location at a well site, including a transportable conveyor belt assembly; one or more silos in fluid communication with a particulate supply line, each of the silo inlets extending through a side wall of the respective silo and disposed at a different location from the others along a longitudinal axis of the respective silo; and for each silo an enclosed chute detachably attachable thereto so as to receive into the chute particulate matter gravity fed out of the respective silo and convey such matter into the housing of the conveyor belt assembly. The silos, the chutes and the housing enclose the particulate matter as it passes from the silos through the chutes and conveyor belt assembly to the target location, to inhibit the release of dust generated from movement of the particulate matter from the silos to the target location.

Abstract: A method for assembling a radio frequency (RF) safe switch and detonator system in a non-RF free environment. More particularly, the method is for assembling an RF-safe switch and detonator system for an oil well perforating gun at a well-site that is in a non-RF free environment.

Abstract: A system and method for axially displacing a portion of coiled tubing into and/or out of a wellbore so that the coiled tubing does not incur a fatigue cycle during such axial displacement, such as, but not limited to a translation system located between the wellhead and the injector head base to axially displace the injector head and, therefore, the gripped coiled tubing, away from and toward, the wellhead.
