摘要： A system and method to eliminate the need for a dummy run comprises a logging assembly to detect the position of one or more blow-out preventer ("BOP") rams and a hang off location. During a logging operation, the logging assembly logs the positions of the BOP rams and wear bushing. The logged positions are then used to determine the correct placement of the subsea test tree ("SSTT") in relation to its hanger. Thus, the need to perform a dummy run is eliminated because correct placement of the SSTT can be determined during routine logging operations.

摘要： The invention relates to content determination of undersea hydrates, in particular to an application method of a device for accurately evaluating the vertical content distribution of an undersea hydrate reservoir, which comprises the following steps: assembling the device into a whole and screwing it into an undersea well; activating natural gas hydrates to produce gaseous substances; opening a directional guide channel corresponding to a thermal excitation system in a working state in S2, so that gaseous natural gas hydrates generated in this horizon enter a screw-in long sleeve through the directional guide channel; collecting, by a gas collection system, the gaseous natural gas hydrates; analyzing and recording components and contents in a box by an optical ranging unit and a resistivity unit; repeating S4 and S5 till the end of one collection cycle; and performing data processing and analysis. In this way, accurate evaluation of the vertical content distribution of undersea hydrates is realized.

摘要： A method for automatically evaluating a survey of a subterranean wellbore includes receiving downhole navigation sensor measurements and automatically evaluating surface sensor data obtained at substantially the same time as the navigation sensor measurements to determine whether or not the navigation sensor measurements were obtained during satisfactory wellbore survey conditions. The navigation sensor measurements are evaluated to determine whether or not they meet certain predetermined conditions necessary for obtaining a satisfactory survey. A survey recommendation is automatically generating based on the automatic evaluations performed.

摘要： A downhole logging tool and method of use for analysing portions of a seafloor borehole in seafloor drilling operations are provided. The downhole logging tool has an underwater chassis housing a power system and sensors including at least a conductivity sensor and a magnetic susceptibility sensor which, preferably, analyse the walls of the borehole. An automatically actuated switch, preferably actuated magnetically, provides power to the sensors from the power system when the downhole logging tool is not located in a designated portion of a seafloor drilling rig (e.g. when the tool is in use traversing a borehole) and removes power when the downhole logging tool is located in the designated portion of the seafloor drilling rig (e.g. when the downhole tool is not in use).

摘要： A downhole communication system for communication between a first and second location in a subsea oil and/or gas well installation. The oil and/or gas well installation comprises out of hole metallic structure comprising a riser 3 running upwards away from the mudline ML, and downhole metallic structure 2 running down into the well. The communication system is arranged so that at least part of a signal path for communications between the first and second locations is provided by the downhole metallic structure 2 such that, in use, data to be communicated between the first and second locations is carried by electrical signals in the downhole metallic structure 2. The communication system further comprises a first noise cancellation arrangement 5 arranged for sensing a noise signal generated in the out of hole metallic structure and arranged for applying a corresponding noise cancelling signal to the out of hole metallic structure or the downhole metallic structure to inhibit introduction of electrical noise into the downhole metallic structure 2 from the riser 3.
