141 METHOD OF CREATING A WELLBORE IN AN UNDERGROUND FORMATION EP00917054.9 2000-04-06 EP1169547A1 2002-01-09 COON, Robert, Joe; FRANK, Timothy, John; MARTIN, David, John
A method of creating a wellbore in an underground formation comprising drilling a borehole in the underground formation using a drilling tubular, capable of being expanded, to which a downhole motor driving a drill bit has been connected, and, after drilling to the desired casing setting depth, expanding the drilling tubular into place to line the borehole by applying a radial load to the drilling tubular and removing said load from the drilling tubular. A sealing material in a fluidic state is preferably pumped between the drilling tubular and the wellbore wall prior to applying said radial load to the drilling tubular which sealing material sets after the radial expansion.

146 METHOD OF CREATING A WELLBORE IN AN UNDERGROUND FORMATION EP93912930.0 1993-06-08 EP0643794B1 1996-11-20 WORRALL, Robert, Nicholas; LOHBECK, Wilhelmus, Christianus, Maria; CHOATE, Paul, Rogerson; DONNELLY, Martin
A method of creating a wellbore in an underground formation is provided, the method comprising drilling a borehole (1) in the underground formation (3), lowering a casing (5) of a malleable material into the borehole, said casing being radially expansible against the borehole wall upon application of a radial load (7) and having a smaller elastic radial deformation than the surrounding formation upon application of said load. The radial load is applied to the casing thereby radially expanding the casing against the borehole wall so as to induce a compressive force between the casing and the surrounding formation.
147 METHOD FOR ISOLATING A WELLBORE FORMATION ZONE EP94911000 1994-03-17 EP0688393A4 1996-04-17 MCPHERSON THURMAN WAYNE II; NG RICKY CHIU-YIN
A method for zone (10, 12, 14) isolation or replacing a damaged or corroded casing (20) with a solidifiable epoxy resin mixture. An amount of the mixture sufficient to form a hardened plastic or solid, underwater or at low wellbore temperatures that is able to withstand downhole stresses, is placed into the wellbore (16) so as to bind with the undamaged casing (20) and close off any thief zone (22). Subsequently, the mixture forms a hardened solid. The hardened solid is milled out if necessary so as to form a resinous casing the size of the original casing (20).

155 Verfahren zum Bearbeiten von Fugen an Betonrohren und Vorrichtung zur Durchführung des Verfahrens EP88117821.4 1988-10-26 EP0315038A2 1989-05-10 Baur, Fritz

Die Abdichtung der Stoßfuge (35) an Betonrohren (1,2) konnte bisher nur durch Vergießen im Sohlenbereich oder durch das Ein­bringen eines als Lippendichtung konzipierten Fugenbandes bewirkt werden. Bei diesen ist die Dichtkraft gering, so daß bei höheren Drücken die im Rohrstrang geführte Flüssig­keit nach außen dringen kann.

Durch das Aufschneiden der Stoßfuge (35) auf eine vorgegebene Tiefe und eine vorgebbare Breite wird die Möglichkeit ge­schaffen, daß strangförmige Dichtungen (43) mit hoher Verpressung eingebaut werden können, und zwar über den gesamten Rohrum­fang, so daß auch für einen hohen Flüssigkeitsdruck eine einwandfreie Abdichtung gewährleistet ist.
