Weatherford International Plc revealed its smart rod-lift solution, comprised of production optimization software, automation, and skilled engineers, boosted uptime 42% and increased production 37% for 40 reciprocating rod-lift wells in Sumatra, Indonesia on Nov. 5. The solution redefined the production strategy for the field, and the operator is currently installing the smart rod-lift solutions on the remaining 160 wells.
The operator objectives were two-fold: first, optimize production in horizontal wells throughout a mature, 200-well, reciprocating-rod-lift asset. Second, reduce downtime caused by premature equipment wear; the pump failure rate was averaging 15 days of downtime.
“Weatherford helped our client to redefine production strategy for this 200-well field,” Manoj Nimbalkar, global vice president, production automation and software, Weatherford, said. “Production optimization software helped the operator monitor and remotely respond to dynamic well conditions, resulting in a 42% increase in uptime by preventing rod failures. Add to that the installation of variable speed drives at each of the 200 well sites in tandem with a rod-string controller to alleviate existing rod-string problems.”
Weatherford production-optimization experts assessed production in the asset along with its failure history. To combat ongoing fluid-pound issues, the team recommended upgrading the automation systems from fixed speed to variable speed. In addition, the Weatherford team recommended a WellPilot variable-speed drive and rod-pump controller unit to regulate the pump speed throughout each stroke. As a final piece of the solution, the team recommended the Weatherford production optimization software platform to enable the operator to monitor real-time well performance.
“The smart rod-lift solution, featuring WellPilot variable speed drives and rod-string controllers, empowered this operator to optimize production by automatically adjusting lift parameters,” Nimbalkar said. “The Weatherford production optimization software platform enabled remote monitoring and management, which enabled a faster response to dynamic well conditions. The success in meeting and exceeding all operator objectives has placed Weatherford and its field-proven solutions at the top of the production plans for the field’s remaining 160 wells.”
The Texas Railroad Commission, though, likely does not have the authority to interfere with contracts between companies to sell gas out of state, says Commissioner Jim Wright.
The refinery shutdowns will depress prices for U.S. crude oil and widen the spread between U.S. and Brent crude, Paul Sankey of independent energy researcher Sankey Research said.
A decade ago, after a milder Texas cold snap led to power outages, FERC probed ways to protect the grid and wrote recommendations for winterization of natural gas and other installations.
