INNOVATIVE TECHNOLOGY

We are proud to design and manufacture all components down to the sensor level, ensuring product integrity and performance. Our suite of Wellbore positioning technologies and services include:

KEEPER GYRO SURVEY TOOLS

The Keeper gyro survey system provides enhanced flexibility for a wide range of survey applications with just a single sensor.  It features high speed options, close interval surveying in casing, drill pipe, and tubing in real-time and memory modes. It’s most notable sightline mode allowing continuous survey and efficient steering even on floating platforms where a standard north seeking gyro would be unable to operate.

KEEPER WIRELINE GYRO

The Keeper wireline gyro is recognized as a benchmark navigation technology and remains the most versatile high-accuracy gyro in the industry. Its unique sensor platform allows for continuous, high-speed gyro surveys from vertical to horizontal in all casing, tubing, and drillpipe sizes.

With its robust and innovative fluid filled design, real-time steering operations are now possible, where a typical MWD would normally be unable to survive due to temperature or vibrations.

KEEPER SLICKLINE MEMORY GYRO

The Memory Keeper is an extension of the Keeper gyro surveying system.  It utilizes long life lithium battery allowing the well to be surveyed completely in memory, and then calculated once the tool is back on surface.  This tool is the optimal choice for operations in locations where access to wireline is either difficult, or cost prohibitive. In addition, coupling with an optional CCL/Gamma sensor allows full depth correlation.

KEEPER ALL ATTITUDE DROP KEEPER (ADK)

The Keeper AdK is a smart drop tool for all-attitude operations including high-angle and horizontal pump-down applications.  The ADK drop gyro system bridges the technology gap between a conventional drop system and the capabilities of the wireline multi-mode Keeper.  This technology allows a definitive survey to be collected while tripping out of the hole, minimizing the rig time necessary.  Operating in high speed mode completely eliminates the stationary time needed at each survey point allowing survey collection at increased intervals if desired.

KEEPER SIGHTLINE Gyro

The Keeper Sightline gyro, is an innovative system designed for complex floating platform steering operations. It operates similar to legacy surface readout gyro systems, by determining the initial orientation via a sight-referenced heading.  Modern north-seeking gyro technology requires absolute stillness during the in-hole survey initialization and gyrocompass.  This can be very difficult to achieve on floating platforms and during near-seabed operations.

The Sightline gyro does not need to be held still for this process reducing  rig time and ultimately delivering significant cost savings.  After the initial heading is known the tool operates in high speed mode allowing full orientation and steering operations to continue.  Lightning fast survey and tool face updates provide the driller with the confidence to drill head without the need stop and re-orient.

Modern north-seeking gyro technology requires absolute stillness during the in-hole survey initialization and gyrocompass.  This can be very difficult to achieve on floating platforms and during near-seabed operations.  SDI has developed solutions for these specialized situations.

MEMORY KEEPER

SDI’s unique Keeper gyro survey system allows for a wide range of survey applications with a single sensor.  This allows SDI to work closely with the customer to determine when is the most efficient time to survey the well.  This flexibility allows high speed, close interval surveying in casing, drill pipe, tubing in both realtime and memory modes.  An industry only sightline mode allows continuous survey and steering even on floating platforms where a standard north seeking gyro would be unable to operate.
