Apply customised QA/QC processes from basic elimination of gross errors to advanced survey management

Well trajectory DB data-mining service description

A wellbore trajectory is a patrimonial asset considered as being highly strategic data. Nowadays, the multiplicity of complex wells in congested environment represents major risks that have pushed the oil & gas industry to better take into account the collision avoidance process in order to avoid disastrous incident.

The drive for improvement is to realise advanced collision avoidance studies between the reference well and the offset wells nearby. This process can be considered as successful if the reliability and the integrity of the well trajectory database are established.

The Well Trajectory DB Data Mining service enables qualifying the integrity and the consistency of all information contained in the database.

Based on a independent quality assessment and a quality control (QA/QC) approach (Level 1 and Level 2 QA/QC), it allows defining a complete reliable and final well trajectory database, in compliance with the client’s company rules.
