ELECTRO-MAGNETIC THICKNESS TOOL (EMT-S)

The Electromagnetic Thickness Tool – Scanning (EMT-S) is designed to detect the damage of tubulars by calculating the remaining wall thickness and corrosion extent. By measuring the phase shift of an induced electromagnetic field, it can accurately indicate the column structure and location of other objects in concentric pipe. High resolution and fast sampling enable EMT-S to scan tubular geometry to provide positional location of nonconformities.

Applications

  • Measure the remaining wall thickness of concentric casing in one run
  • Determination of the type(s) of damage: pits, penetrations, cracks in transverse or longitudinal plane
  • Determination of inner casing penetration

Features

  • Compact Design
  • Ability to adjust decay time window during logging to capture the response of outer casings.
  • High resolution
  • Through-tubing screening
  • Stainless steel scanning
  • Well completion monitoring: Corrosion progress and repeatability

MULTI-FINGER CALIPER TOOL(MFC)

The Multi-Finger Caliper Tool has been designed to provide the most accurate Pipe ID caliper measurements in the industry. The high quality output data allows for 3-D imaging and calculation of corrosion, penetration, or scale deposition. The MFC tool can be combined with some other of our well integrity tools using a Wireline Telemetry Cartridge(SRO) or Downhole Memory Cartridge(Memory). All MFC tools have a built-in orientation sensor that allow for relative bearing and deviation data correction. Temperature correction is hardware based so no software drift files are needed. The mechanical design allows for easy finger replacement in the field.

Applications

  • Tubular damage analysis
  • Perforation mapping
  • Quantification of scale build up and corrosion
  • Accurate location mapping of holes and anomalies
  • Large casing (up to 21”) inspection with extension kit

DUAL SPECTRAL NOISE TOOL (DSNT)

The Dual Spectral Noise Tool (DNST) is used to detect the incoming noises in the wellbore generated at different spectral frequencies from different sources. By analyzing the frequency spectrum, the nature of fluids may be determined and leaks can be located. Dual receivers allow the tool to reduce the effect of road noise while logging and also provide redundancy for stop checks. Noise logging is applicable to oil/gas/water wells. It increases the success rate of locating leaks and channeling in tubulars. When combined with temperature and flow rate measurements, extensive quantitative interpretation can be performed. Real time monitoring combined with the ability to save the audio to digital file provides ability to meet greater compliance regulations.

Applications

  • Location of production interval and productivity evaluation
  • Fluid identification and flow rate evaluation
  • Inspection of the channeling behind casing, leaks, backflows, sand production, and effect of packers
  • Features

ELECTRO-MECHANICAL SETTING TOOL (EMST)

The EMST is a unique electro-mechanical downhole setting tool, capable of delivering up to 90,000 lbs of linear force which can be used to set, or un-set, wellbore devices in a wide range of tubing and casing sizes.

EMST is suitable for use on any conveyance method including slickline, digital slickline, electric line, and coiled tubing.

Description

The EMST is governed by an electronic controller that outlines the operational parameters of the tool. Once an initiation command has been acknowledged by this controller then the EMST will activate. Electrical power is supplied from the alkaline battery pack and is routed to a small dc motor, which provides a high-speed, low torque input into a gearbox. The gearbox takes this high speed, low torque input and generates a low speed, high torque rotational output. This rotational output is coupled to a linear actuator mechanism, which converts the rotational movement to linear movement, and in turn, pulls the slick rod slowly upwards.

Applications

Installation of wellbore devices such as:

  • Bridge-plug
  • Packers
  • Valves
  • Cement retainers
  • Downhole gauges

  • Features

    • Less equipment and personnel required

MEMDump Bailer (MDB

The MEMDump Bailer is unique in its application for completing tasks previously accomplished with explosives. Our gravity feed bailer system provides the ability to dump cement, acid, molted plastics, etc. without the use of explosives.

Description

The MEMDump Bailer system is a microprocessor-based tool which combines three major assemblies, the Battery Section Electronic Control Section and Valve Section. The Valve Section is used to hold the material being ‘dumped’ in the bailer body. Once the time Window has opened, Temperature Threshold is reached and there is no Turbulent Motion, the valve will open allowing the material in the bailer body to dump out of the tool.

Numerous safety features are also incorporated in the MEMDump. These features include a Time Window, Temperature Thresholds, and Turbulent Motion circuitry coupled with several other fail-safe internal proprietary hardware mechanisms.

Ultra-High Expansion (UHX) Sealing Solutions

With industry-leading expansion and high-pressure, in-flow deployment capability, our UHX solutions help to solve a range of complex plugging, sealing and isolation challenges in a variety of wells.

For wells with narrow restrictions or with small diameter completion tubing, this technology provides the ideal expansion ratio and strength to deliver a reliable seal in lower sections of the well, that may be up to three times wider in diameter.

These outstanding solutions are suited to completion, production optimization and abandonment applications in oil and gas wells and enable the repurposing of wells for carbon capture and gas storage by enabling the plugging of the lower completion.

Flexibility in the design of the packers, pack offs and plugs makes the range suitable for a variety of well configurations and tubing/casing/liner sizes.
