Many of the Romanian onshore fields have been in operation since the middle of the last century. During this period, the operations were executed with proven technologies and processes without putting particular emphasis on continuous improvements, as a result by the early 2000s, many of the existing facilities, technologies, and processes in the fields were outdated and not complying with latest norms / standards. To improve the current situation, OMV Petrom decided to initiate several field redevelopment programs (FRDP) for the high potential of onshore and offshore fields in Romania. The primary objectives of the programs were to:

• Maximize and accelerate incremental oil and/or gas production with enhanced recovery processes,
• Unlock new reserves with new technology,
• Improve efficiency of operations and reduce operational expenses,
• Ensure compliance with environmental regulations,
• Improve working environment for personnel according to HSE criteria
