    Abstract: Systems and methods are provided for laser heating in a fluid environment (30). Such a system may include a laser generator (12) and a laser output sub (16) separate from one another via an optical fiber (18). The laser generator may generate a heating laser pulse over the optical fiber. The laser output sub may emit the heating laser pulse to heat a substrate (22) in the fluid environment (30). To enable the heating laser pulse to pass between the laser output sub (16) and the substrate (22), the laser output sub may dispense a laser- transmissive optical grease or a laser-transmissive magnetic fluid, or may generate a vacuum cavitation bubble in the fluid between the laser output sub (16) and the substrate (22).

    Abstract: Drilling assemblies, systems and methods enable a wellbore to be drilled and lined with a slotted liner. A drilling system includes a liner assembly with a drill string in a bore thereof. The drill string and the liner assembly can be selectively coupled together to restrict relative motion between the liner assembly and the drill string. The liner assembly includes a slotted liner portion through which fluid may flow. As the drilling system is used to drill a wellbore, the liner assembly is simultaneously positioned within the wellbore. Once the wellbore is drilled to a desired depth, the drill string can be disengaged from the liner assembly and retrieved from the well. Production fluids such as oil and gas may then be transferred uphole through the liner assembly.

    Abstract: It is desirable to secure a lower end of a down hole assembly in the event of a down hole failure, such as a fractured drive shaft, enabling recovery of the bottom hole assembly and drill bit. To secure the lower end of the down hole assembly, a catch apparatus according to embodiments herein may be used, the catch apparatus including a rotating bearing having a distal end threadably coupled to a distal portion of a drive shaft. The apparatus may also include a stationary bearing having a proximal end threadably coupled to a distal end of an outer housing. A catch ring may be threadably coupled to a proximal end of the rotating bearing, the catch ring having a shoulder radially overlapping a shoulder of the stationary bearing.

    Abstract: A method for characterizing properties of a sample that employs a test apparatus including an isolated sample cell and pressure sensor where the isolated sample cell is loaded with the sample and gaseous test fluid to perform a number of different tests to derive properties of the sample. The tests can be performed over different parameters, such as different applied pressures of the test fluid to derive parameters related to apparent gas permeability of the sample as a function of applied pressure, different gaseous test fluids to characterize dependence of permeability of the sample on mean free molecular path or pressure, with both adsorptive and non-adsorptive test gases to characterize at least one property related to adsorptive interaction between the adsorptive test gas and the sample, and with samples of varying saturation levels to derive a measure of at least one property of the subsamples at corresponding saturation levels.

    Abstract: A method for characterizing properties of a manufactured rock sample that employs first and second test apparatus. The first test apparatus includes a sample holder and associated pressure sensors, wherein the sample holder allows for a pulse of test fluid to flow through the sample, and the pressure sensors measure pressure upstream and downstream of the sample as the pulse of test fluid flows through the sample. The second test apparatus includes a sample cell and associated pressure sensor, wherein the sample cell has a configuration where the sample cell is isolated and filled with test fluid under pressure and the pressure sensor measures pressure of the isolated sample cell. The first and second test apparatus are used to measure bulk properties of the sample. The sample is partitioned into pieces, and the second test apparatus is used to measure properties for different size-groups of such sample pieces.

    Abstract: A charge assembly for incorporation into a downhole tool to induce pressure at an interior of the tool during a downhole application. The assembly includes a reactive powder metals that is particularly configured of a reaction rate slower than that of a high energy explosive directed at the application. Thus, upon triggering of the explosive and downhole application in a high pressure well environment, reaction of the powder metals may serve to substantially reduce any pressure differential at the tool. As such, shock related damage due to sudden introduction of pressure differential wave to the tool may be minimized.
