CASE STUDY
Reduced numbers of wells from critical to normal condition
Reduce drilling risks using offset well events, logging trends analysis and cross plot in real time
The RTOC provides engineering solutions to increase the control over the drilling process
Real-time engineering empowers the client to prevent and control future drilling events
TRAFFIC LIGHTS METHODOLOGY
CRITICALThe well is classified in Critical status when the drilling operation conditions require significant changes within the original drilling program to reach the goal in the well
ALERTSThe well is classified in Alert status when operative conditions and time are not within range or according to the plan
NORMALThe well is classified in Normal status when operative conditions and time are within range and according to the plan
REAL TIME GEOPRESSURE
