Enhanced Pipe Detection Tool (ePDT)

The enhanced Pipe Detector Tool (ePDT) is a two-inch O.D. advanced ferromagnetic metal thickness evaluation instrument. The integrity of multiple concentric tubulars strings can be evaluated in-situ. In most cases, this eliminates pulling the production tubing string, or disassembling the surface completion hardware to facilitate data acquisition.

ePDT, is GOWell’s Next Generation thickness instrument. It is based on evolutionary pulsed eddy current physics which permits quantitative thickness measurement capabilities. This allows evaluation of tubulars ranging from 2-7/8-inch to 26-inch O.D.


  • Warrior™ acquisition system compatible
  • 2-inch O.D. – deployed centralized
  • Clear real-time visualization for QC and onsite evaluation
  • Combinable with all Pegasus Series Tools
  • Quantitative 4 to 5 pipe thickness evaluation (dependent on total metal thickness)
  • Pre-job planner software that combines a powerful forward modeling module and simulation tool
  • Proprietary post-processing module built-in to ViewWell™ Well Integrity Platform


  • Simultaneously assess metal thickness of multiple tubulars strings
  • Locate collars and shoes of concentric strings
  • Aid P&A risk management by determining integrity of adjacent strings
  • Determine tubulars condition prior to workovers or re-fracs
  • Verify condition of casing patches and patched casing.
  • Establish trend-lines for tubulars degradation over time
  • Pin-point leak source location by combining with ANT, MFC, RBL, PLT, etc.
The ePDT is fully combinable with GOWell’s Pegasus instruments, including Multi-Finger Imaging Calipers (MFC), Array Noise Tool (ANT), Production Logging Tools (PLT) and our Digital Radial Bond Tool (RBL). The combination yields a comprehensive evaluation of well integrity, providing accurate thickness information for multiple pipe strings as well as leak detection, multi-phase fluid flow and cement bond quality.

During real-time logging via WarriorTM the software provides a comprehensive wellsite quality control display which offers clear visual indication of tool performance and pipe conditions. Post processing is performed with GOWell’s proprietary module contained in the industry leading Well Integrity Evaluation Platform – ViewWell™. When using ViewWell, all MFC, ePDT and Passive Noise data can be processed, viewed and interpreted side-by-side within a single software platform.

Vertical Production Logging (V-PLT)

The Alkhorayef Vertical Production Logging Tools (V-PLT), manufactured by Sondex, are used to gather fluid data which is used to maximize hydrocarbon recovery or manage fluid profiles for injection wells.

The V-PLT log data can be used to:

  • Identify producing zones and the fluids from them – oil, water, gas or mixtures
  • Detect leaks, low pressure zones or problem zones that require remedial work to repair the damage or block off zones
  • Calculate qualitatively the flowrates of oil, gas and water from each producing zone
  • Profile injection fluids - these are typically water or gas

Our vertical production logging tool string will typically include.

  • GR
  • CCL
  • Pressure
  • Temperature 
  • Density  
  • Capacitance  
  • Dual caliper 
  • Spinner (full bore, in-line, continues).


Advanced Horizontal Production Logging (H-PLT) with the Multiple Array Production Suite (MAPS)

The Alkhorayef Multiple Array Production Suite (MAPS), manufactured by Sondex, is used for deviated and horizontal production logging.

MAPS is a combination of advanced horizontal production logging tools that provides holdup data from resistance array tool (RAT) and capacitance array tool (CAT), and directional and speed of multi-phased flow from the spinner array tool (SAT) measured around the wellbore.

MAPS makes it possible to provide quantitative estimates of the volumetric flow rate of each phase with a much higher degree of confidence and thus provides vital information for reservoir management.

Our horizontal production logging tool string will typically include.

  • Pressure
  • Temperature 
  • Capacitance array tool (CAT)
  • Resistance array tool (RAT) 
  • Spinner array tool (SAT)
  • Dual caliper 
  • Full bore spinner


Mechanical Puncher Tool – K-Punch

K-Punch tool is manufactured by Kaseum is used to quickly and safely punch communication holes through tubing and casing. The kaseum 4.5” tubing K-Punch assembly utilises a hydro-mechanical system to safely punch up to a maximum of five 0.563” diameter communication holes in a single deployment. The 4.5” tubing K-Punch can be retrofitted to the bottom of either the 3.6” OD, 2.72” OD or 2.125” K-Set setting tool and uses its linear stroke to energize. The hydraulic system. The 4.5” tubing K-Punch does not require jarring or explosives to operate and will effectively penetrate through the tubing with a simple electronic command. The 4.5” tubing K-Punch consists of a 3.6” OD or 2.590” OD Hydraulic Actuator section that can be configured with up to five 3.6” OD Punch Head assemblies depending on the flow area required.

K-Punch features:

  • Electronic control: The K-Punch is initiated and controlled electronically for increased accuracy.
  • Modular design: Allowing multiple Punch Heads and Hydraulic Actuators for various string configurations.
  • Punch Phasing ability: Multiple Punch Heads can be rotationally phased to suit operational requirements.
  • Surface testable; Like the K-Set, the K-Punch can be tested prior to deployment to ensure correct function.
  • Non-explosive: A hydraulic system eliminates the need for explosives, reducing the safety hazard and logistical challenges involved in the deployment of explosives. 
  • Built in safety systems: The K-Punch is designed with multiple safety mechanisms to protect the tool and user from the dangers associated with pressurized systems.
  • Emergency disconnect: In the unlikely event of a tool failure mid-operation and the tool string is stuck downhole, then the hydraulic chamber can be mechanically vented by jarring to allow the tool string to be recovered.
