Deepwater - field production could be more efficient by reducing the size of production hosts , according to a study by employees of a number of production units . If contracts were structured in a different way and the operators had the chance to operate the offshore field for a longer period, it might have been possible to use smaller hosts and subsea production systems, thus reducing both Capex and operational expenditure (Opex). Researchers found that focusing on the host , rather than the entire production system or individual wells , could significantly reduce both capital and operational expenditure . In a paper delivered to the 2008 SPE Asia Pacific Oil and Gas Conference and Exhibition , they argued that operating smaller hosts would result in a longer field life and that timed replacement of such facilities could produce larger amounts of oil and gas in better conditions .
