The equipment is used for drilling of directional and horizontal wells.
Irrespective of the required telemetry and measurements types the applied equipment reduces the drilling time and minimizes the well inclination intensity. During drilling operations MWD and LWD equipment provides to the specialists the data necessary for navigation and evaluation of reservoir properties.
Modern systems for solving of special tasks include some tools with many measured drilling parameters sent to the surface at a high speed and high density even during high rate of drilling. The equipment ensures reliable and accurate measurements for all main types of drilling operations on a real time basis.
Equipment used for heavy duty drilling of complex wells is facing additional requirements: Real time data transfer, continuous measurements near the drill bit, measurement of vibration and impact stress levels, measurement of bit speed, automatic maintenance of zenith and azimuth angles.
These tasks can be solved by rotor controlled systems. The equipment allows drilling of well with more smooth profile due to absence of large displacements, reduction of friction and better cleaning of the well bore.
Higher rate of drilling with continuous rotation of the drill stem prevents the drilling tools from sticking, reduces time for clean out of cuttings, decreases adverse impact of drilling mud upon the productive formations, and ensures faster putting of wells into production.
