About Us
Direct Systems
Direct Systems provides to the drilling and resources industry, an extensive and high quality package of directional steering and borehole surveying services, ranging from; North Seeking Gyroscopes, Surface recording Gyroscopes, Borehole Steering, Phyiscal Properties, Planning and Monitoring of boreholes, Surface Surveying, Drill site setups, and borehole location pick-ups.
The senior members of the company all have extensive industry experience, and have brought together many years of data acquisition, directional steering, and borehole surveying knowledge from civil, mining and exploration environments.
Direct Systems have been involved on projects in Europe, Africa, and Asia; being an essential component to the success of various drilling programs for companies such as; Xstrata, Barrick Gold Corporation and Antofagasta.
Direct Systems regularily acts as the liaison between the drilling companies and its clients to ensure all directional drilling techniques are considered in achieving a target, with the ultimate goal of time and cost saving for all parties. Once provided with target co-ordinates that need to be tested, Direct Systems designs, establishes, monitors, and produces the final borehole trajectory data for the client.
What is Directional Drilling?
Directional Drilling is the method of controlling the path of a borehole along a predetermined course to a defined target, utilising guidance and deflection tools. Direct Systems utilises RSS steering tools from the UK to control direction and torque and with the help of the drillers display display allows the driller to see the path of the directional cut.
Where is Directional Drilling Used?
- Oil and Gas Industry
- Utility and Pipeline Construction
- Mineral Exploration
- Accurately placed exploration boreholes provide operational efficiency
- There is an increasing usage of deep drilling in Mineral Exploration, as near surface exploration targets and mineral deposits are exhausted
Method of Borehole Control
The trajectory of a borehole can be controlled in various of ways;
- Altering the configuration of the bottom hole assembly
- The use of wedges or whipstocks
- By using directional mud motors
How Does Directional Drilling Benefit a Project?
- Less drilling metres are required to intersect a greater number of targets. This can achieve significant cost and time savings.
- Precise borehole placement ensures accurate ore body definition and quantification.
- Multiple targets drilled from one drill site assist when geographical and environmental factors restrict the placement of drill sites.
- Geological targets are intersected when deep boreholes are kept to design.
- Boreholes intersect target zones at the optimum strike angle.
- Difficult ground conditions can be isolated and cased off, yet still allowing the intersection of multiple lower targets.
Survey Instrumentation – Why Survey Boreholes?
- Directional Drilling is reliant on there being a means of determining the borehole location.
- The control and monitoring of the borehole progress and target intersection is achieved using electronic instrumentation;
- Surface Read-out Steering Tools
- Electronic Magnetic Multi-shots
- Gyroscopic Systems
