摘要： An offshore universal riser system may include a valve module which selectively permits and prevents fluid flow through a flow passage extending longitudinally through a riser string. An anchoring device may releasably secure the valve module in the passage. A method of constructing a riser system may include the steps of installing the valve module in the passage, and installing at least one annular seal module in the passage. The annular seal module may prevent fluid flow through an annular space between the riser string and a tubular string positioned in the passage. Drilling methods may include injecting relatively low density fluid compositions into the annular space, and selectively varying a restriction to flow through a subsea choke in a drilling fluid return line. The riser string, including housings for the various modules and external control systems, may be dimensioned for installation through a rotary table.

摘要： A wet connector for latchingly connecting an electric cable between surface equipment and a previously installed electrically powered well tool at a remote, downhole location in a well for transmitting electrical energy or signals thereto or therefrom. This wet connector comprises a male connector on the downhole well tool and a female connector on the electric cable. The female connector carries a non-conductive liquid which is expelled therefrom during mating with the male connector to wash and cleanse the electrical contacts of both the male and the female connectors. One form of the wet connector is released electrically (reverse polarity being used), and another form of the connector is released by tensioning and slackening the electric cable a predetermined plurality of times. Systems using such wet connectors are disclosed, as are methods for their use. The wet connector can be used in conjunction with an electric cable for installing certain tools in a well, especially where it is desirable to deposit such tools gently with no jarring.

摘要： A method of operating an isolation valve can include continuously transmitting a signal to a detector section, and a control system operating an actuator in response to the detector section detecting cessation of the signal transmission. A well system can include an isolation valve which selectively permits and prevents fluid communication between sections of a wellbore, a remotely positioned signal transmitter, and the isolation valve including a control system which operates an actuator in response to detection of a signal by a detector section. Another well system can include an isolation valve interconnected in a tubular string, and the tubular string being cemented in a wellbore, with cement being disposed in an annulus formed radially between the isolation valve and the wellbore.

A well drilling system can include a control system which compares a parameter signature for a drilling operation to an event signature indicative of a drilling event, and a controller which controls the drilling operation automatically in response to the drilling event being indicated by at least a partial match between the parameter signature and the event signature.
