| 186 | Procédé de récupération d'un tube intérieur de carottier, du type verrouillable et coulissable dans un train de tube extérieur, en forage montant, et dispositif de récupération prévue à cet effet | EP80201101.5 | 1980-11-21 | EP0052672B1 | 1985-03-20 | Lambot, Honoré Joseph |
| 187 | Method and apparatus for conducting wireline operations in a borehole | EP84400069.5 | 1984-01-13 | EP0119872A1 | 1984-09-26 | Walulik, James J.; Lanmon II, C. P. |
For conducting wireline operations in a deviated borehole, a dual or two-stage locomotive (44) pulls a wireline cable (40) through both the entire length of a drill string (35) and the entire length of a stinger (25) therein to dock with a tool (20) at the bottom of the stinger. The inner or second-stage locomotive then pulls the stinger out into the borehole by pushing on the bottom end of the stinger to prevent buckling the stinger. The stinger and drill stem can be assembled to virtually any length, without requiring pre-wiring. The risk of buckling upon retracting the stinger back into the drill pipe, by pulling on the cable, is reduced by the use of the special configuration provided by the present invention. |

| 189 | Wireless downhole tool positioning control | US14545298 | 2015-04-20 | US10138688B2 | 2018-11-27 | Don Umphries; Gabe Williger |
| For a free falling well tool sub having one or more pipe bore centering cages, a collapsible material cone secured inside of the centering cage half length with the cone base opening in the downhole direction restricts the rate of pipe bore fluid flow past the cone and thereby restricts the descent rate of the tool. The rate of descent may be regulated with fluid flow by-pass apertures in the sub. A collapsible material cone in a bore centering cage having a base opening in the up-hole direction may be used as piston to drive the tool sub along horizontal segments of a deviated well bore. Both cones may be used separately or together. | ||||||

| 197 | UNIVERSAL DRILLING AND COMPLETION SYSTEM | US15452534 | 2017-03-07 | US20170175468A1 | 2017-06-22 | WILLIAM BANNING VAIL III; ROBERT L. DEKLE; DAMIR S. SKERL; JAMES E. CHITWOOD |
| Methods and apparatus are described to drill and complete wellbores. Such wellbores include extended reach horizontal wellbores, for example in shales, deep subsea extended reach wellbores, and multilateral wellbores. Specifically, the invention provides simple threaded subassemblies that are added to existing threaded tubular drilling and completion equipment which are used to dramatically increase the lateral reach using that existing on-site equipment. These subassemblies extract power from downward flowing clean mud, or other fluids, in an annulus to provide additional force or torque on tubular elements within the wellbore, while maintaining circulation, to extend the lateral reach of the drilling equipment and completion equipment. These added elements include combinations of The Leaky Seal™, a Cross-Over, The Force Sub™ and The Torque Sub™. The use of such additional simple elements allow lighter drilling equipment to be used to reach a given lateral distance, therefore reducing drilling costs. | ||||||
| 198 | Method of selective release of an object to a seat on a frack plug from immediately adjacent the frack plug | US14203072 | 2014-03-10 | US09650857B2 | 2017-05-16 | Jason C. Mailand; Daniel S. Matthews |
| In a fracking context the object that will ultimately block a passage in an isolation device is introduced into the zone with the bottom hole assembly. The object is not released until the guns fire to create a pressure spike in the borehole that triggers the object retaining device to release the object. The retaining device is placed in close proximity to the isolation device and its setting tool to allow a larger object and passage in the isolation device to be used. If the guns misfire, the object is not released and comes out with the guns. The replacement guns can be pumped in because the passage in the isolation device has stayed open during the misfire. Direct and indirect object release in response to pressure created from the firing of the guns is contemplated. | ||||||
