Abstract: A flow back system for separating solids from a slurry recovered from a hydrocarbon well. The system includes a V-shaped tank with a first series of baffles configured to cause the settling of solids that are moved by a shaftless auger to a conduit fluidly connected to hydrocyclones mounted over a linear shaker. The overflow from the hydrocyclones is discharged through a second conduit back into the tank for processing by a second series of baffles resulting in a clean effluent. The clean effluent is recirculated in the well.

Abstract: A method of improving natural gas recovery from a subterranean hydrocarbon reservoir includes at least one renewable energy source that is electrically coupled with a heat conducting element. The heat conducting element is positioned in a perforated section of a wellbore that traverses into the subterranean hydrocarbon reservoir. A temperature of the subterranean hydrocarbon reservoir is maintained above a cricondentherm temperature so that liquid condensation may be prevented at a final production time. In order to maintain the temperature within a required temperature range, an internal temperature, an internal pressure, and a set of reservoir properties are monitored and then utilized to plot a phase diagram that can be used to detect liquid condensation. If liquid condensation is detected, an electrical output of the renewable energy source is adjusted in order to control the temperature of the subterranean hydrocarbon reservoir at a producing end of a production tubing.

Abstract: Methods and kits for assembling a flow cage assembly are provided. The flow cage assembly may be used in a traveling valve or a standing valve of a downhole pump. In some embodiments, the kit comprises a tubular body having an axial bore, a tubular insert, and a retaining element.

In some embodiments, the interference fit between the retaining element and the tubular body may reduce or eliminate a possible failure point within the flow cage assembly.

Abstract: The invention relates to a method of conducting a perf wash cement (“P/W/C”) abandonment job in an offshore oil or gas well annulus (2), in particular the washing or cementing operation using a rotating head (6, 8) with nozzles (7, 9) dispensing wash fluid or cement at pressure. Certain values of parameters of a washing or cementing job have been found surprisingly to affect the quality of the job, or the degree to which they affect the quality of the job has been unexpected. These include including rotation rate of the tool, the direction of translational movement of the tool, and the volume flow rate and pressure per nozzle of cement or wash fluid (and hence nozzle size).

The method may include, when a hydraulic fracturing stage profile is not available, prompting configuration of hydraulic fracturing pumping stage parameters for the current hydraulic fracturing stage profile.

Abstract: A boring tool that is moved by a drill string to form an underground bore. A transmitter transmits a time varying dipole field as a homing field from the boring tool. A pitch sensor detects a pitch orientation of the boring tool. A homing receiver is positionable at a target location for detecting the homing field to produce a set of flux measurements. A processing arrangement uses the pitch orientation and flux measurements with a determined length of the drill string to determine a vertical homing command for use in controlling depth in directing the boring tool to the target location such that the vertical homing command is generated with a particular accuracy at a given range between the transmitter and the homing receiver and which would otherwise be generated with the particular accuracy for a standard range, different from the particular range. An associated system and method are described.
