Technical notes

What information is needed to choose a deep well drilling rig?

Machine selection is not made on depth alone. Target diameter, geology, drilling method, carrier preference and auxiliary equipment needs are assessed together.

No two sites are the same

Ground conditions, target depth, diameter, transport mode and the drilling method to be used determine the right configuration of the machine. That is why the right machine starts with the right site data.

The Qawsar team assesses this information together with the customer before the quote. It starts from a standard product option, then adapts the technical scope to site and operating needs.

Target depth and well diameter

The Qawsar product family covers depth classes from 400 m to 2,500 m. The drilling capacity in the catalog defines the standard product class; actual capacity may vary with well diameter, formation, drilling method and operating conditions.

Formation and drilling method

Geological conditions and drilling method directly affect the choice of rotation system and of mud and air equipment.

Carrier preference

The machine can be built on a truck chassis or on a semi-trailer. The right solution is determined by assessing the customer's existing truck, site mobility and logistics preferences.

Auxiliary equipment

Main items defined at the quote stage together with the project goal:

  • Mast and chassis dimensions
  • Engine and alternator selection
  • Mud pump and piston pump
  • Pneumatic controls and auxiliary systems
  • Carrier vehicle or trailer compatibility

Information to share for a quote

The following information speeds up quote preparation:

  • Target drilling depth
  • Target well diameter
  • Formation or site information
  • Drilling method
  • Country of operation
  • Carrier preference: existing truck chassis or semi-trailer
  • Required auxiliary equipment
