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.

Triple Tube Coring Systems

Triple Tube Coring Systems

Triple tube coring is the term used when a sleeve is placed inside the inner barrel. While it reduces core diameter slightly, the XLI low invasion system guarntees the least amount of fluid invasion possible into a core sample leaving almost the full diameter in an insitu condition and providing a full useable sample.

Triple tube coring assemblies are by far the most used and requested systems from the Petrotool suite of tools and are more economical where long core intervals are present when compared to disposable inner tubes.

Available in both wireline retrievable and conventional configurations triple tube coring is the answer where core containerization is required, generally in soft and friable formations, for long term storage of core before analysis, areas where roads are rough or transport takes extra time and when the core needs to be frozen.

The triple tubes minimize the amount of core handling required and can prevent mechanical fracturing when coupled with a laydown cradle and surface core management system.

Available Liners
