Engineering support of drilling fluids

Drilling fluids play an enormous role in the construction of oil and gas wells, starting with the cleaning of the wellbore from cuttings and warnings from geological complications and emergencies, ending with a qualitative opening of the productive formation and further high rate of production well flow.

Non-destructive Testing

Non-destructive testing is used in the manufacturing, installation, repair, reconstruction and technical diagnosis.


One of the main activities of our company is the manufacture of parts and assembly units of any industry.

Wireline Retrievable Coring Systems

Wireline Retrievable Coring Systems

The largest cost on any coring program will be rig time. Wireline coring reduces or eliminates the number of trips required and thereby reduces the overall cost of your coring program when long intervals of core or numerous zones are required

The Wireline Retrievable Coring system is the solution in areas where frequent jamming is a concern, on core intervals of 35M or more in soft lithologies that can't be recovered with a long barrel,when coring multiple target formations or when the goal is to bring the sampe to the surface quickly to preserve a natural state or resource saturation.

All configurations of Petrotool’s wireline retrievable coring systems are compatible with our Drill Ahead Feature. This gives you the ability to clean the hole as required on long intervals, drill between target formations, drill out the overhole for logging or TD the well, all without the time normally required to trip pipe while eliminating the safety hazards associated with laying down a string of drill pipe.

The heart of the Petrotool’s wireline system is a self-contained building containing a premium wireline fitted with accurate digital depth gauge and weight indicator as well as a workshop and temperature regulated core handling facility all in a 24' x 7' footprint operated and maintained by certified Petrotool personnel.

Petrotool has designed and developed the Wireline Retrievable Systems to incorporate our Low Invasion technology. This has led to world leading ROP, Recovery and Quality of core.

Petrotool continue to enhance the Wireline Coring System to allow for better core recovery, lower costs, and high core quality. Our vast experience provides Petrotools’ clients unsurpassed expertise in this coring application.
