  • Patent number: 9702214
    Abstract: A cap for sealing a wellhead assembly of a subterranean well and suspending well assets (e.g., tubing, rods, etc.) therefrom within the well to facilitate production at the well after a period of abandonment. For instance, a decompletion process may be performed on a particular well to be temporarily abandoned which may include disconnecting a pumpjack (e.g., horsehead unit, pumping unit, etc.) from a wellhead of the well, breaking (e.g., disconnecting) the wellhead at the first flange (e.g., closest to ground level) to leave a casing head of the wellhead exposed, and/or the like. Ends of a tubing string and a rod string disposed within the subterranean well may be respectively secured within portions of the disclosed cap. The cap may then be placed and secured over the exposed casing head to limit entry of foreign objects and debris into the well.

  • Patent number: 9644330
    Abstract: A self-propelled construction road milling machine, includes a machine frame and a milling drum housing, in which a milling drum is arranged. The machine includes a drive unit with which the height of the scraper blade of a scraper device can be adjusted in relation to the milling drum. A control unit for the drive unit adjusts the height of the scraper blade and a measurement device measures the distance between the lower edge of the scraper blade and the milled material. The control unit is designed in such a way that the scraper blade is height-adjustable depending on the height of the milled material remaining in the milled track. The control unit ensures that, on the one hand, the milled material can come out of the milling drum housing unimpeded behind the milling drum in the direction of work and, on the other hand, that the milling drum housing is shut above the material that is coming out.

  • Patent number: 9638017
    Abstract: Batch initiation and/or exploitation phases of in situ solution mining of a mineral from an underground evaporite mineral stratum. The initiation phase may comprise a lifting step which employs a lithological displacement (lifting) of this stratum from an underlying non-evaporite stratum with application at the strata interface of a lifting hydraulic pressure greater than overburden pressure by a solvent suitable to dissolve the mineral; a soaking step for dissolution of mineral upon contact with stationary solvent, and a brine extraction step. The method may further comprise one or more exploitation phases carried out after the initiation phase. The exploitation phase may comprise a partial filing or filling step with the same solvent or different solvent than during lifting, another soaking step, and another brine extraction step. The lifting, cavity partial filing/filling, and brine extraction steps are being discontinuous. The evaporite mineral stratum preferably comprises trona.

  • Patent number: 9631433
    Abstract: The invention relates to a method for sinking or introducing cavities in rock, wherein the face of the cavity (2) is melted using electrical plasma generators. In order in such a method to produce an energy density at the face of the cavity (2), the energy density being sufficient to completely or partially evaporate the in-situ stone, the invention proposes arranging a heat shield (4) immediately over the face of the cavity (2), the heat shield (4) forming with the face of the cavity (2) a dynamic pressure space (7) in which a temperature of more than 2000° C. is established at a pressure of more than 2 bar by heating with plasma generators (8). This supply of energy is sufficient to melt the stone in-situ at the face of the cavity (2), to completely or partially gasify it and to remove it from the cavity (2).

  • Patent number: 9581006
    Abstract: In-situ solution mining method of an ore bed, particularly containing trona, which comprises exposing to a solvent an ore region inside a borehole drilled in the ore, and dissolving a desired solute within the exposed region to provide a liquor and create a voided ‘undercut’, such undercutting making the ore susceptible to gravitational loading and crushing. Unexposed ore falls into the undercut by gravity without breaking the ore roof resulting in exposure of fresh ore to the solvent and in preventing solvent exposure to contaminating material near the roof. The desired solute is eventually dissolved away in the entire bed from its floor up to its roof. Solvent injection may be delivered through a conduit positioned inside the borehole, and may be moved by retracting or perforating the conduit. The method may employ an advancing undercut initiated up-dip and traveling down-dip, or a retreating undercut initiated down-dip and traveling up-dip.
