Borehole Planning
Today, most directional-well planning is done on the computer. Modern computer technologies, such as 3D visualization and 3D earth models, have provided geoscientists and engineers with integrated and interactive tools to create, visualize, and optimize well paths through reservoir targets. Furthermore, recently developed directional drilling systems allow more-complex directional-well trajectories that are designed to optimize drilling programs to get more information out of less meter drilled. The 3D visualization together with the earth model allow detailed planning to maximize geological information gained from the drilling program as well as minimize the time, work and cost needed to obtain such information.
AZIWELL planning services
AZIWELL personnel can assist in bore hole planning with the aim to maximize obtained geological info, while keeping the cost as low as possible, All done by experienced field engineers who have extensive experience from directional drilling projects, working as a team with project geologists and the drilling company. Regardless if the aim is to intersect multiple targets from a limited location or master hole, follow a tunnel track or just keep a hole within give boundaries, we do our best to find the best solution for each individual project.
Mineral exploration
Straight drilling
Planning of corrections in drifting bore holes in highly deviated formations.
Horizontal drilling
Planning of drill holes starting from surface or underground and turn it horizontal or to a specific inclination to intersect the ore body at a specific angle or reach a targets that otherwise would be inaccessible due to surface topography.
Multiple Kick-Offs
Planning of multiple Kick-Offs from a single master hole to reduce the cost of transport drilling as well as coring and casings in the overlaying formations. With proper planning there are virtually no limits of the number of branches you can have, thus the saving potential is considerable both money wise and for minimizing nature impact.
Pilot holes for raise bore and utility holes
Planning of pilot holes for later raise boring or hole opening to speed up penetration rates for other types of drilling in order to intersect underground tunnels or caverns.
Civil applications
Geological pre-investigation for tunnels or caverns
Planning for drill holes starting from surface or underground that turn horizontal or follow a tunnel track. Thus providing crucial information about the geology along the planned route of the tunnel.
Producing accurate holes for freeze curtains
Planning of freeze curtains in tunnel or cavern projects, where each hole need to be within certain limits to each other to ensure that the curtain can solidify the formation properly.
Controlled slope drilling for sewage and water tunnels
Planning of bore holes for sewage or water tunnels that need to follow a specific path or slope to ensure positive gravity flow of water through the tunnel.
River-crossing applications
Planning of bore holes for pipelines that cross beneath rivers to install fiber-optic cables, power lines or other infrastructure.
