摘要： An acoustic detection of a discrete acoustic signal allows to detect a leak behind a casing (23) of a borehole. An acoustic amplitude (AA) is sampled during a recording time period (24; 64) at a determined position along the tube. Time intervals (26; 66) are defined inside of the recording time period (24), and for each time interval (26) the measured acoustic amplitudes are processed to obtain respectively a corresponding power-frequency spectrum (261). A plurality of the power-frequency spectra are analyzed to identify the discrete acoustic signal by detecting time and frequency dependant changes of power. Preferably the processing involves a Fourier transform analysis. A power-frequency time plot is used to conveniently identify the discrete acoustic event.

摘要： A method for determining the size of tubular pipe to be inserted into an interval of cased or uncased borehole is disclosed. The position of the borehole wall or innermost casing surface in the interval is determined and a window length that is less than the length of the interval is defined. A series of windows along the interval is defined and for each window, the determined position of the borehole wall in that window is used to define a polygon, the edges of which are defined by the parts of the borehole wall closest to the borehole axis in that window. The maximum size of pipe diameter that will fit inside the polygon in each window without intersecting the edges is determined and the size of pipe to be inserted into the interval selected based on the maximum size of diameter pipe determined for each window.

摘要： An assembly for positioning a well access line in a well. The assembly is located between a supply of well access line and a well, with the line running through the assembly and to the well. Multiple pulleys are incorporated into the assembly about which a well access line such as a conventional wireline may be wrapped. The pulleys are biased to one another such that slack in the line may be stored at the assembly and drawn on in the event of line tension spiking up to a predetermined amount. As such, tension in the line may be kept to a minimum so as to avoid damage to the line during a well access operation. Furthermore, should the tension in the line fail to come back down to below the predetermined amount, the well access operation may be halted in an automated manner. Halting may proceed while continuing to allow take-up of the slack in the line until completed halting of the operation is achieved.

摘要： Systems and methods for treating internal tissue defects, such as septal defects, with clip-based devices are provided. An exemplary clip-based device includes a tubular body having at least a first and a second deflectable member coupled thereto. The first and second members are coupled on opposite ends of the tubular body and configured to deflect between an undeployed configuration and a deployed configuration. In the deployed configuration, each member extends outwardly away from the tubular body in a position configured to abut a tissue surface. The first and second members are preferably configured to maintain a tissue wall therebetween and at least partially close any opening in the tissue wall.

摘要： An assembly for monitoring load on a drum during an operation in a well with a well access line deployed from the drum. The assembly may include multiple line detection mechanisms for acquiring real-time information relative to dynamic characteristics of the lone over the course of the operation. The assembly also includes a processor for computing the real-time information in light of pre-stored information relative to physical characteristics of the line and the drum. As a result, real-time monitoring of a load on the drum may be achieved. Thus, the operation may be adjusted in real-time as necessary to avoid over-loading of the drum. Additionally, a drum load history may be recorded so as to better account for the true condition of the drum following successive operations.
