摘要： A method of drilling a subsea wellbore includes drilling the subsea wellbore and, while drilling the subsea wellbore: measuring a flow rate of the drilling fluid injected into a tubular string; measuring a flow rate of returns; comparing the returns flow rate to the drilling fluid flow rate to detect a kick by a formation being drilled; and exerting backpressure on the returns using a first variable choke valve. The method further includes, in response to detecting the kick: closing a blowout preventer of a subsea pressure control assembly (PCA) against the tubular string; and diverting the flow of returns from the PCA, through a choke line having a second variable choke valve, and through the first variable choke valve.

摘要： An assembly to recover hydrocarbon gas from a seabed comprises one or more self-propelled drilling devices that include hydrocarbon sensors and a sublimation mechanism to induce sublimation of crystallized hydrates into hydrocarbon gases. As the drilling device moves through the wellbore, hydrocarbon deposits are detected and the sublimation mechanism induces sublimation of the deposits to release hydrocarbon gases up through the formation to the seabed. A bladder is positioned atop the wellbore to capture the release hydrocarbon gas and transfer it to a surface vessel for collection.

摘要： An offshore system with a rig (1) and a cantilever (20) having a rigid cantilever structure with an operational end. The rig is provided with a first support rail (10) which extends along a side of the deck (3) supporting structure. Travelling and swivelling assemblies are arranged between the first support rail (10) and the cantilever beams (27). The rig is provided with one or more second support rails (35) that extend over the deck in a direction transverse to the first support rail. The system has a cantilever inner end carrier device (40) which travels over and engages on said one or more second support rails. This device is connected via a vertical pivot axis swivel (41) to a connector part of the rigid cantilever structure at or near its inner end to provide a rotation axis at a fixed location relative to the structure for the rotational motion of the cantilever, the cantilever inner end carrier device holding the cantilever inner end relative to the deck.
