case-studiesAmong those who have employed Genesis’ software and services are major companies such as Petrobras, ENI, Talisman, Anadarko, Apache and RWEDEA. Some of this work has been registered in conference papers. The results shown in those Case Studies include Genesis products and services among other solutions.

Logo_petrobrasThe development of post-salt wells offshore of Brazil has been one of the most challenging projects in history of E&P. Faced with water depths of 2000+ meters – a salt layer 2000 meters thick – to reach reservoirs at 7000 meters below sea level, has necessitated the use of technological and procedural techniques never utilised before.

In two years (2009 to 2011) of exploration of these fields many technologies were tested and improved. In the paper ROG12_1310 Petrobras describes the systematic approach implemented to analyze, plan and follow-up the development of the drilling operations campaign in those fields. The paper also focuses on overall process improvement.

The assumption was to apply a risk analysis tool which uses previous data to analyze performance and plan future timeframes. The goals of this process are the continuous improvement of execution, as well as process control for each operation. Looking into previous performance, new interventions were planned more accurately and further improvements were studied. The frequent follow up of the drilling intervention was done using the statistical base to compare the most recent results.

At operational level it was possible to see if the last operation was done in the 1st, 2nd, 3rd or 4th quartile of its related statistical distribution, as well as to verify the difference within P10 and P90, which indicates the control of each operation execution process. The same process was done for some rig related operations and for the whole intervention at the end of it. Close contact with the intervention progress was kept and actions taken on any major deviation from the plan.

The application of the methodology resulted in significant improvement in the drilling process, as shown in the figure below:

AnadarkoPetroleumCorporationDaily drilling operations generate large amounts of data but, surprisingly, a significant proportion of these data are not utilized in a manner that shortens the learning curve and promotes drilling efficiency. Anadarko, in the published paper SPE87177, demonstrates how drilling analysis methodology helped identify performance gaps in a West Central Canadian field.

The methodology used is based on ways of properly measuring the data and is characterized by the questions:
• Where are we now?
• What is possible?
• How do we get there?

By applying this tool, significant cost savings to the tune of CAD$7 million have been achieved during this period of measurement.

The successful method used is based on BCT (Best Composite Time), or practical Technical Limit, which basically create an entire well plan with the best times already achieved on any single operation. This is a moving target, as once achieved, there is a new level. This continues until it reaches a plateau where only new technologies can provide further enhancements. This is represented in the figure below:
