SCOTON

System Description of SEMWD-2000 The system is made up of downhole tools and surface equipment. The downhole tools connected in the drilling-string can measure directional parameters and GR parameters, then send them to the surface. The waves are caught by the Surface Receiver. After amplification, de-noising and digital data acquisition, the data can be recovered, displayed and recorded by the computer, the directional parameters are displayed on the driller's monitor. Application Area of SEMWD-2000 MWD of gas drilling and mixed medium drilling wells. Vertical drilling control. MWD of shallow formations and coal seam gas wells. Horizontal wells and directional wells that suitable for electromagnetic wave transferring. Parameters Measured: Well deviation, azimuth, tool face, temperature, GR, resistivity, annular pressure, etc. Technical Specifications of SEMWD-2000 Measure range and accuracy: Deviation: 0～180° ±0.2° OD: 48mm Azimuth: ...

SCOTON's Array Noise Tool (ANT)  uses an array of highly sensitive wide-band acoustic sensors to detect sound produced downhole by fluid movement. DESCRIPTION of Array Noise Tool (Advanced Leak Detection) The tool employs a set of innovative differential measurements to enable excellent rejection of unwanted noise such as "road noise" produced while the tool is moving in the wellbore. The sensor  array  also  allows  propagation-direction processing to further extract weak fluid movement sounds from behind multiple pipes. Features of Array Noise Tool (Advanced Leak Detection) Total of 38 Hydrophones Sensor Configuration: 3 monopole + 6 differential X & Y Differential + Wave Propagation Provides accurate results while logging continuously Spectral Analysis Excellent (> 30dB) Road Noise Rejection Azimuthal Sensitivity Combinable including simultaneous RCBL logging HOW IT WORKS? By coupling both differential sensors with ar...

Multi-finger caliper logging tool is the latest in technology and reliability. Based on sound engineering and machining, and combined with input from field experience, Multi-finger caliper logging tool  is making itself known across the globe. The  Multi-finger caliper logging tool  provides a high resolution log along with the standard directional measurements expected from a modern caliper. It is completely Warrior Compatible, and does not require special keys and panels to operate. The tool has an integral digital telemetry cartridge which has proven to be extremely robust, operating easily on a wide range of electric lines. If you have a Warrior Data Acquisition System, you can begin logging right away. Multi-finger Caliper Raw Log The MFC sends an I.D. image (one sensor for each finger) plus additional curves: deviation and relative bearing for orientation and some control curves such as cablehead voltage and temperature. In addition there are some calculated cu...

The Magnetic Thickness Detector (MTD) is a 1-11/16 in O.D corrosion measuring instrument primarily run through tubing with the unique ability to simultaneously inspect tubing and the casings behind it. The integrity of the casing string can be evaluated with neither the requirement for costly workover rig, nor the time consuming removal of the tubing completion. Induction of Magnetic Thickness Detector-E (MTD-E) SCOTON's latest generation MTD tool is capable of evaluating quantitative thickness measurements of three concentric pipes. The state-of-the-art instrument combines a high power transmitter, improved signal-to-noise (SNR) electronics and fully configurable acquisition. This flexible approach allows a wide range of evaluations under different conditions and conveyance systems. A simple engineer selection of the functional mode allows features such as Logging in large pipes (up to 18-5/8 inches) Fast logging of single pipes...

The Radial Bond log Tool provides proven superior reliability and responsiveness even in thin cement sheath conditions. With circumferential cement bond evaluation, the RBL identifies channels, in addition to standard cement bond logging. The main application of the Radial Bond Log Tool is to evaluate hydraulic isolation between producing and non-producing zones– a key factor needed to assess the integrity of the well. Description of Radial Bond Log In addition to standard cement bond amplitude (CBL) through near receiver (3-ft), and variable density log (VDL) through far receiver (5-ft), the RBL tool provides a cement map through eight receivers (Radial @2Ft ), each segment covering 45° section of the pipe which gives a complete 360° evaluation of bond integrity. A single piezoelectric transmitter with a transducer central resonance frequency of 20KHz provides the source of energy for all 8 piezoelectric sector receivers, as well as ...

The top of Pegasus Star telemetry tools for logging is a standard GO connection. The lower connection is a 13 pin threaded collar that supports the latest generation Pegasus Tools. A 13-4 pin adaptor is available to support 4 pin generation Pegasus series tools. PegasusStar SRO telemetry system has the following features Auto-connect After power-up, the PegasusStar telemetry will automatically connect and establish communications between surface and downhole. There is no setup or configuration necessary – the engineer can just focus on logging. Front panel LED and software GUI provides immediate feedback on the connection status. Link speed and all status information is reported via warrior. Self-Adapting PegasusStar will automatically adjust to the maximum uplink speed supported by the wireline cable and conditions. The system's automatic noise suppression reduces any interference. Half-duplex Uplink is based on Digital Multicarrier Modulati...

SX and SR Landing Nipples SX and SR landing nipples are run into the well on the completion tubing to provide a specific landing location for subsurface flow control equipment. These landing nipples feature common internal profiles making them universal. The SX landing nipple is used in standard weight tubing. The SR landing nipple is typically used with heavyweight tubing. The completion can include as many selective nipples with the same ID in any sequence asdesired on the tubing string. This versatility results in an unlimited number of positions for setting and locking subsurface flow controls. SXN and SRN Landing Nipples This equipment is designed for use in single nipple installations or as the bottom nipple in a series of SX or SR landing nipples. These landing nipples have the same packing bore ID for a particular tubing size and weight. SX and SXN landing nipples are designed for use with standard weight tubing. SR and SRN landing nipples are designed for use with he...
