1. WO/2015/112021 ONE TRIP BLOWOUT PREVENTER CLEANING AND PRESSURE TESTINGWO30.07.2015
E21B 33/043
PCT/NO2014/000005ARCHER OIL TOOL ASCONNELL, Paul, L.
A bottom hole assembly (BHA) has a plug below a debris catcher and an optional telescoping joint. A cleaning tool is above the debris catcher with another cleaning tool further up the BHA that is designed to clean the riser that extends up from the BOP. The plug is spotted and released to commence the BOP cleaning and the riser cleaning. The cleaning tools can be reconfigured to allow through flow after the cleaning is done so that the rams can be closed around a drill collar and a pressure test take place. With the BHA above the BOP the rams can be closed against each other for another pressure test from above. In a variety of options for the method, the plug can be retrieved after released or left in the hole in the set position.

E21B 7/04
PCT/NO2015/050016NATIONAL OILWELL VARCO NORWAY ASKYLLINGSTAD, Åge
There are described methods for controlling the direction of a wellbore trajectory during directional sliding drilling by means of a drill string having a drill bit rotatable, by means of a mud motor, around a drill bit rotation axis at its lower end, the direction of the drill bit rotation axis defining a tool face, wherein one of the methods comprises the following steps: a2) obtaining data indicative of the torque of the mud motor; and b2) calculating a reactive twist angle of the drill string by multiplying the obtained torque from step a2) by the torsional drill string compliance, wherein the method further comprises the step of : c2) rotating the drill string, by means of a drill string rotation means, an angle substantially equal to but in the opposite direction of the calculated reactive twist angle. There are also described systems for executing the methods as well as computer program products comprising instructions for causing a processor to perform the methods as described herein.
