摘要： The present invention provides a method and system in which signals from the surface are sent by changing flow rate of the drilling fluid supplied to the drill string (20) during drilling of a wellbore. The signals are sent based on a fixed or dynamic time period schemes so that the sent signals cross a dynamic threshold value in a known manner. A controller downhole (140) sets the dynamic threshold and determines the number of times a parameter, such as voltage, relating to the changes in the flow rate crosses the set dynamic threshold. Based on the number of the number of crossings and/or the number of crossings and the timing of such crossings, the controller (140) ascertains the signal sent from the surface for use downhole.

摘要： The casing cutter disclosed herein is useful for severing downhole tubulars and comprises a body (11) a cutting head (14) cutting blades, and actuators for operating the cutting head and cutting blades. Cutting is accomplished by rotatingly actuating the cutting head with an associated motor, and then radially extending the cutting blades away from the cutting head. In one embodiment, the cutting head includes a cutting member that pivotally extends from the cutting head upon rotation of the cutting head. In another embodiment cutting members extend from the cutting head due to centrifugal forces associated with rotating the cutting head.

摘要： A method of determining a formation pressure during drawdown of a formation comprises sampling fluid from a formation using a downhole tool. A fluid sample pressure is determined at two different times during the drawdown. The fluid sample pressures are analyzed using a higher-order pressure derivative with respect to time technique to determine the formation pressure during the drawdown. Another method of determining a formation pressure during drawdown of a formation comprises sampling fluid from a formation using a downhole tool. A fluid sample pressure is determined at two different times during the drawdown. The fluid sample pressures are analyzed using at least two analysis techniques to each determine an estimate of the formation pressure during the drawdown.

摘要： A control device (2) for a program-controlled household appliance (1) has a writeable memory area (18) into which program data can be transmitted from a physically separate data source (7) by remote data transmission, in particular by means of a telephone network (13) or over the Internet (14). The program data which has been transmitted can be integrated by the control device (2) into its functional range. In this way, the control program of the control device (2) can be supplemented with data which can be drawn from a central data source (7). Large quantities and the latest version of the program data can be stored in said data source. It is also possible to only equip the control device (2) with a control program without operating program data at first. Said control program can subsequently be used to add program data according to a remote data transmission, whereby the program data can be specifically transmitted according to the exact type of household appliance and/or the installation site.

摘要： A system for reverse circulation in a wellbore include equipment for supplying drilling fluid into the wellbore bit via at least an annulus of the wellbore and returning the drilling fluid to a surface location via at least a bore of a wellbore tubular. The system also includes devices for controlling the annulus pressure associated with this reverse circulation. In one embodiment, an active pressure differential device increases the pressure wellbore annulus to at least partially offset a circulating pressure loss. In other embodiments, the system includes devices for decreasing the pressure in the annulus of the wellbore. For offshore application, annulus pressure is decreased to accommodate the pore and fracture pressures of a subsea formation. In still other embodiments, annulus pressure is decreased to cause an underbalanced condition in the well.
