DynaString® Gauge Carrier
HAL24450
TUBING CONVEYED SYSTEM FOR MEMORY AND
REAL-TIME GAUGES
OVERVIEW
The DynaString® gauge carrier is a full bore tool that carries memory and realtime
gauges (DynaMem™ and DynaGauge®) and DynaLink® telemetry tools in external
slots. Depending on the carrier’s outside diameter (OD), the design includes two or
four slots. The number of gauges that can be installed in a carrier is determined by
carrier slot length and number of slots specified in the Equipment Specifications table
below and the length of the gauges to be installed.
While the 5-in. OD carrier is offset 0.4 in. from the inside diameter (ID), the
larger OD models are concentric with the ID. In all the cases, the ID of the tool is
concentric with the tubing string so that the ID is always maintained, enabling both
unrestricted flow through the tool and wireline-tool/drop-bar passage. Depending
on which of the various end adapters are run on the carrier, the effective OD of the
tool can vary. The 5.5 in. OD high-temperature carrier features a metal-to-metal seal
backed up by elastomer seals.
FEATURES
»» Designed for severe well conditions, including sour gas and high temperature
»» Ability to carry up to two 1.25-in. OD standalone DynaMem memory gauges ported
to tubing pressure and additional gauges ported to annulus pressure in each slot
»» Ability to carry one DynaGauge* ported to either internal tubing or annulus
pressure, and depending on the configuration, additional standalone DynaMem
memory gauges to read either tubing or annulus pressure
»» Easy to install and retrieve standalone and telemetry gauges
»» Patented T-pressure adapters, enabling for quick installation and versatility of
porting to either the tubing or annulus
»» Acoustic coupling for use with DynaGauges
»» Adaptable to 1.25-in. OD mechanical gauges
BENEFITS
»» Permits unrestricted flow through the tools
»» Enables wireline operations to be run
»» Carries multiple gauges
»» Multiple tubing or annulus gauge porting
* The additional standalone DynaMem memory
gauge can be added only with the DynaGauge tool
with the standard battery. With a double battery,
there is no space for any extra DynaMem memory
gauge in the slot.

Notes:
1
Absolute pressure rating will be based upon the pressure rating of the gauges installed in the carrier.
2
Differential pressure is the difference in pressure between the casing annulus and the tool ID.
3
The values of tensile, burst, and collapse strength are calculated with new tool conditions, Lame formulas with von Mises’ Distortion Energy Theory for burst and collapse
strength, and stress area calculations for tensile strength.
