Total's Khalid Mateen also provided his thoughts on EOR planning and execution.
"There are challenges in planning EOR projects in deepwater and also limitations compared to onshore EOR," said Mateen, who serves as VP of Engineering Technology for Total E&P Research and Technology USA.
Offshore developments typically use a much wider well spacing, and the oil found in deepwater tends to be more viscous, he
The biggest difference is the cost of drilling each well, and that cost results in fewer wells and less familiarity with the downhole conditions, and with the reservoir.
has several initiatives directed at solving some of the deepwater EOR challenges, Mateen
These include qualifying a polymer injection process to use in shallow, high permeability reservoirs with high viscosity oil, such as at Dalia.
Subsea separation and processing are in application at Pazflor, and Total
is participating in development of the SPRINGS sea-water injection equipment.
While there is no "silver bullet" answer to deepwater EOR challenges, Mateen
said that it is best to identify an EOR option early, and then employ an integrated approach that involves all disciplines.
