摘要： The present disclosure relates to apparatus and methods for evaluating an earth formation though a drillstring during tripping of the drillstring, particularly locating an area of circulation loss in a wellbore. The apparatus may include a neutron source and at least one radiation detector, which may be disposed on a logging instrument, configured to be dropped or pumped into a drillstring at the end of drilling. The logging instrument may be configured to make measurements through a homogenous portion of the drillstring while the drillstring is being tripped. The apparatus may include a memory and processor for logging data for later retrieval. The method may include adding a radiation absorbing substance to drilling fluid in the wellbore; exposing the earth formation to neutron radiation; and making a plurality of measurement indicative of radiation measurements of sigma or distinct energy peaks along the wellbore.

摘要： An access port for providing subcutaneous access to a patient is disclosed. The access port includes a septum including palpable identification indicia thereon. In particular, the access port in one embodiment includes a body that defines a fluid cavity and a needle-penetrable septum covering the fluid cavity for providing access thereto. The septum defines an outer periphery. One or more palpation features are included on the septum. The palpation features each include a portion that extends in a radial direction beyond the outer periphery of the septum. The palpation features are therefore disposed relatively farther away from each other, simplifying palpation and identification thereof after the port has been subcutaneously implanted into a patient. The palpation features can be indicative of an attribute of the port, such as its ability to withstand fluid pressures and flow rates associated with power injection, for instance.

摘要： A visualization system for visualizing data obtained in a borehole includes a processor configured to process the data based on user input and instructions and provide output for display on a display device. The system may also include a computer-readable medium configured to store the instructions, the instructions including commands to output values of two or more types of parameters at two or more depth values. The instructions may include commands to provide a perspective top-down or bottom-up fly-through display of the borehole including a zoomed-in image of values closest to a user. The processor may also output a display of a photographic image at each of the two or more depth values based on a correspondence between the values of the two or more types of parameters and the plurality of parameters associated with the photographic image.

摘要： An access port for subcutaneous implantation is disclosed. Such an access port may comprise a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body. Further, the access port may include at least one feature structured and configured for identification of the access port subsequent to subcutaneous implantation. Methods of identifying a subcutaneously implanted access port are also disclosed. For example, a subcutaneously implanted access port may be provided and at least one feature of the subcutaneously implanted access port may be perceived. Further, the subcutaneously implanted access port may be identified in response to perceiving the at least one feature. In one embodiment, an identification feature is engraved or otherwise defined by the access port, so as to be visible after implantation via x-ray imaging technology.

摘要： A multifunction adaptor for an open-ended catheter that allows placement of the catheter while minimizing the risk of air embolism or blood loss through the open (proximal) end of the catheter body. In one variation, the design allows passage of a standard guidewire for “over-the-guidewire” placement techniques and a connection for catheter flushing using a standard syringe. In another variation, the multifunction adaptor is configured for coupling a tunneler to the proximal end of a catheter.
