Title: Industrial robot with broad working region in the horizontal direction
Inventor: SUN-WOO HEE-KWON
IPC: B25J1/00
Filed: 1991-10-30
Granted: 1997-12-09
Abstract: Disclosed is an industrial robot whose horizontal working area is enlarged.  In the robot, the first, third and fifth axes are rotation axes of the horizontal direction.  The second axis performs a straight movement in a horizontal direction. The fifth axis performs a straight movement in a vertical direction. Thereby, the horizontal working area of the industrial robot can be enlarged.  Also, if the actual working area is reduced, the second and fifth axes for straight movement go back to reduce the driving force.

Abstract: A method and device for making lateral openings (11) out of a wellbore (1) in a ground formation (2) where at least one laterally directed drill string (28) is movable in the axial direction inside a motherbore tubular (4), and where the leading end portion (16) of the drill string (28) is equipped with the drill bit (18) that is driven by a rotatable drill string (28), wherein the method includes: - connecting a fluid driven engine (22, 24, 26) to the rotatable drill string (28) inside the motherbore tubular (4); and - directing flow in the motherbore tubular (4) through the fluid driven engine (22, 24, 26) to create rotation of the drill bit (18) via the drill string (28).

Title: Expandable Drillable Shoe
Inventor: ERIC JAMES CONNOR
Filed: 2017-12-31
Abstract: An expansion system is assembled by coupling a piston assembly and a solid cone assembly to an adjustable cone assembly within an expandable tubular having inner sleeve disposed in a portion thereof. The expansion system is run into a wellbore. The piston assembly is activated to move the solid cone assembly downward through the inner sleeve so as to expand the inner sleeve and the portion of the expandable tubular having the inner sleeve. The adjustable cone assembly is shifted from a retracted position to an expansion position within the inner sleeve. The adjustable cone assembly is moved upward through expandable tubular while leaving the solid cone assembly and the inner sleeve coupled to expandable tubular. The solid cone assembly and the inner sleeve may be drilled or milled. Fig 1.

Title: In-situ process to produce hydrogen from underground hydrocarbon reservoirs
Inventor: GATES IAN D
Filed: 2018-08-08
Abstract: A hydrocarbon reservoir is treated with heat to induce gasification, water-gas shift, and/or ‎aquathermolysis reactions to generate gases including hydrogen. The hydrogen alone is ‎produced to the surface by using hydrogen-only membranes in the production wells.‎

Title: Acidizing Treatment Fluids for use in Subterranean Formation Operations
Inventor: BELAKSHE RAVIKANT S
Filed: 2019-01-21
Abstract: The present disclosure relates to acidizing treatment fluids for use in subterranean ‎formation, such as wellbore, operations for dissolving iron sulfide scale, such as ‎iron sulfide scale in sour conditions. Such treatment fluids comprise an aqueous ‎base fluid; an acid; a chelating agent of methylglycine diacetic acid trisodium salt; ‎and a hydrogen sulfide scavenger blend comprising 3-hydroxybutanal, ‎crotonaldehyde, acetaldehyde, and a solvent base fluid.‎
