101 WELL TOOL MODULES FOR RADIAL DRILLING AND ANCHORING EP15833516 2015-08-19 EP3183418A4 2018-07-25 SANDKLEIVA ARE
A drilling module is for radial drilling in a well and an anchoring module is for use in a well tool. The drilling module has a piston for receiving a drill for the radial drilling, and for displacing the drill in a radial direction towards a wall of the well and a cylinder for receiving and guiding the piston. Both the piston and the cylinder are guide-free and of a non-circular shape, at least in a portion, to prevent relative rotation between them. The anchoring module has an extent in the axial direction of the well. The anchoring module includes a displacement device arranged to push against a portion of the wall of the well to press the anchoring module against an opposite portion of the wall of the well. The displacement device is oblong in the axial direction of the anchoring module.

103 REDRESSING METHOD AND REDRESSED COMPLETION SYSTEM EP16728984.2 2016-06-15 EP3310991A1 2018-04-25 HAZEL, Paul
A redressing method for arranging an inner production casing within an existing production casing in order to re-establish production of hydrocarbon-containing fluid in a well, comprises providing the inner production casing to having a substantially constant inner diameter, the inner production casing comprising spaced first and second annular barriers. Each annular barrier has a tubular metal part and an expandable metal sleeve surrounding the tubular metal part. Each barrier has an inner face facing the tubular metal part and an outer face facing an inner wall of the existing production casing. The inner production casing has an outer unexpanded diameter which is smaller than the first inner diameter of the existing production casing. The existing production casing is redressed by introducing the inner production casing into the existing production casing, arranging the first annular barrier on one side of the first inflow section and the second annular barrier on the other side of the inflow section, thereby isolating an inflow of fluid from the first inflow section, encapsulating the first inflow section of the existing production casing by expanding the expandable metal sleeves of the first annular barrier and the second annular barrier, thereby isolating the first inflow section.
104 HYDROCARBON FILLED FRACTURE FORMATION TESTING BEFORE SHALE FRACTURING EP16736550.1 2016-06-02 EP3303771A1 2018-04-11 SANTARELLI, Frederic Joseph
A method of increasing hydrocarbon production by hydraulic fracturing in shale formations by using an a-seismic process of cyclic injection of cooled aqueous fluid at a low rate with shut-in periods to induce tensile failure in the formation and create a fracture network of high and very high conductivity fractures with sufficient lateral extension in a completed well. A final single cycle of aqueous fluid and proppant is used in which the volume of proppant has been determined from measurements of the downhole pressure. Further fracture parameters being: volume of the very high conductivity fractures, lateral extension of the very high conductivity fractures, surface of the very high conductivity fractures and estimation of the global fracture network shape are determined and analysed after each injection cycle.
