20080266577 | Apparatus for Measuring an Internal Dimension of a Well Bore - An apparatus for measuring an internal dimension of a well-bore comprising a tool ( | 10-30-2008 |
20090195244 | ELECTROMAGNETIC IMAGING METHOD AND DEVICE - An electromagnetic imaging method for electromagnetically measuring physical parameters of a pipe CJ, CC by means of a plurality of measuring arrangement ZMA, MCMA, MonMa, ImMA comprising a plurality of transmitter coil ZTX, LFTX, DTX and a plurality of receiver coil ZRX | 08-06-2009 |
20100044036 | TRACER INJECTOR TOOL FOR WELL INVESTIGATION - A tool system for monitoring a flow of liquid within a borehole. The tool system comprises a plurality of tools disposed on a longitudinal axis of the tool system. The plurality of tools comprises at least a first injector tool for ejecting in the borehole a tracer and a detector tool to detect the ejected tracer. The tool system further comprises a standard digital bus traversing at least a portion of each tool of the plurality of tools. The standard digital bus allows a communication between each tool of the plurality of tools. | 02-25-2010 |
20100307738 | WELL CLEANING APPARATUS - An apparatus for removing debris from a well is provided. The apparatus comprises a tool body having a head, a chamber, a connector, a conduit, and a filter. The head has an opening and comprises protrusions extending from the outer surface for moving debris. The chamber is in the tool body to store debris. The connector is for attaching the tool body to a drilling system. The conduit is connected to the opening in the head to convey debris and fluid from the well to the chamber. The filter is in the tool body to limit the size of the particles that can pass into the drilling system from the chamber. In use, fluid flow and the protrusions move the debris from the well and through the apparatus. | 12-09-2010 |
20110185805 | VARIABLE THROAT VENTURI FLOW METER - A variable throat Venturi flow meter includes an upstream pipe section having an upstream cross-sectional area, a throat section having a variable throat cross-sectional area that is smaller than the upstream cross-sectional area, and a plurality of section-varying elements adapted to temporarily vary the throat cross-sectional area to allow a downhole tool to pass through the throat section. | 08-04-2011 |
20130255370 | Variable Throat Venturi Flow Meter - An apparatus for performing a well test operation includes a closed chamber testing system having a downhole flow control device. In some embodiments, a method of performing a well test operation includes performing a well test operation with a closed chamber testing system having a downhole flow control device and estimating the reservoir properties based on pressure and flow data measured during the well test operation. | 10-03-2013 |
20140290350 | Well Data Acquisition Tool Probe Guard - A probe assembly for use with a well data acquisition tool includes a probe and a probe guard. The probe includes a body and a tip extending from the body along a longitudinal axis of the tip to a terminal end. The tip defines a length and a surface area along the length and is configured for sensing one or more well characteristics. The probe guard extends about the tip of the probe and leaves a majority of the surface area of the tip exposed to a flow that is angularly offset from the longitudinal axis of the tip of the probe. | 10-02-2014 |
