To optimize its drilling, ChevronTexaco company developed in collaboration with a technology solution called Halliburton Well Design and Execution Collaboration Center or WellDECC.

This is a control center where all information is centralized drilling fields (especially offshore) in real time. The data are collected through field sensors and sent via cable and satellite. Therefore engineers, technicians and Earth scientists have a representation in 3 dimensions of the situation of a well for viewing its various parameters (temperature, pressure, seismic activity, etc.). They can, in a concerted manner, assess the risks and take appropriate decisions in case of problems. This system is also a reserve management tool, from production to transport. According to Cambridge Energy Research Associates (CERA), a research firm on oil, this digital approach could increase in the years 10 the world's hydrocarbon reserves 125 million barrels (Less than 2 days of global consumption). It could also allow the oil companies to reduce the staff on site, to increase production of 10%, reduce operating costs and raise 25% of 6% renewal oilfields. Different IT companies like Microsoft or SAP are very interested in this new market, valued at one billion dollars for the next years 5 by IBM (which devoted a thousand specialists). But if Shell is developing its own control structure, the rest of the oil companies shows still chilly. Despite considerable profits over 70% of them will not be planning in the immediate major investment in this sector, according to a study 2004 Forrester Research.
