Survey systems for oil & gas well conductor installations, from Boretech International.

EPOCH Straightshot

Epoch Straightshot inclinometer offers push button multiple surveys on demand - no waiting for a preset clock and up to 4-hour survey run time. Tool can be run inside the drill string via wireline for efficient rapid data retrieval.

Accurate electronic sensing system +/-0.1° and 0.01° resolution.

0 to 30° calibrated inclination range, survey results shown on printed ticket. EPOCH SS tool has greater depth capability and can record wellbore temperature up to 150°C

To improve accuracy BoreTECH have a number of seating rings and TOTCO centralises that can be inserted into the BHA.

Conductor Survey Tool (CST2)

The CST2 has a Stainless Steel component housing with a pneumatic centralizing system that is operated from the surface and can be utilized for depths to 100+ meters. Surface LCD screens displays accurate real time data via an umbilical similar to an ROV.

The CST2 uses pneumatic systems to lock itself against the inside of the casing at set intervals, being usually 2 or 5 meter increments. The CST2 measures a 2 meter length of casing at a time, to determine any dog-leg sections and to build an accurate picture of deviation.

This system can accurately monitor the casing while utilising drill and drive installation methods. BoreTECH’s CST determines the azimuth or direction angle of drift so can be used for calculations for collision avoidance. For as-build surveys the CST can be deployed using a tripod, so a drilling rig is not required on site.

Measuring range - 0-360º
Operating temperature - 1ºc to +50ºc
Power supply - 12v
Tool weight (less poles) - 20 Kg
Actuator air pressure - 60 PSI
Umbilical length - 100m+

DeviShot

The DeviShot is an electronic multishot survey instrument for measuring the path of boreholes, in non-magnetic environments. With simple to use android software, single and multi-shot function, and quality that drillers can rely on, the DeviShot is widely accepted as the tool of choice for a range of mining and civil applications such as exploration boreholes, grout curtains and blast holes.

Running gear - Integrated
Diameter - 30 or 35/1.18" or 1.38"
Pressure - 500bar/7250psi
Temperature range -10° to +70°C/14° to 158°F
Azimuth accuracy ±0.5°
Inclination accuracy ±0.1°
Tool face accuracy ±0.2°
Azimuth range 0°-360°
Inclination range -90°- +90°

The highly durable DeviShot is a leading survey instrument for measuring the drill hole path, in a non-magnetic environment. It can be used in most drilling applications and will for instance easily operate as single shot, multi shot, with constant or variable depth interval, and for surveying in and/or out.

The instrument is operated through the user-friendly DeviShot Android application, equipped with intuitive step by step operation, also offering all the functionality needed for advanced users. Each survey data point is independent of the other and passes through an internal quality control system.

With the ability to pre-load the local TMI values of the drilling environment, any data points affected by magnetic disturbance or movement, are clearly flagged, alerting the operator after download of the survey data.

The DeviShot is designed for efficient operation and built to last through an integrated running gear set up, which includes a robust titanium structure, our innovative Brilliant Blue Technology (BBT) activation system, and patented wireless antenna, all enabling quick set up, data transfer and download; without having to open the instrument or utilize cables. So, regarding pre survey set up time and efficiency, the DeviShot is ready to go at all times.

In addition, a long life, internal, replaceable battery means the DeviShot instrument can remain at the drill site without needing to be charged.

DeviShot is available in the standard 35mm diameter version and in a slimmer 30mm version, for smaller diameter requirements.

RANGER Explorer Survey System

Is a Multi Functional Magnetic Surveying System developed to make drill hole surveying simpler and less time-consuming for the operator.

Using a memory system with communication through an infra-red data link the system is operated from the Ranger Explorer Controller (REC). The REC sets the tool in operation and when surveys are completed, downloads and displays the survey data. All raw survey data is recorded and placed in the REC memory for use/download at a later date.

Once completed, the survey data can be transferred easily to a Laptop or Personal Computer for analysing with the RANGER 3 Dimensional Survey Analysis Software (SAS 3D). With the SAS 3D the magnetic and gravity readings can be automatically set to distinguish between Magnetic or gravity effected readings.

TOTCO Tool

TOTCO inclinometers are run inside the drill string during open hole drilling.

For rapid data retrieval reasons the deployment method is via a wire line this also minimizes disruption to the drilling operation.

Measuring range (inclination) - 7º
Measuring accuracy - +/- 0.5º
Operating temperature - N/A
Power supply - N/A
Tool weight (less poles) - 10 Kg
Wire line length - Varies
