Up)
ExxonMobil Upstream Research Company (NYSE: XOM) announced today that it has awarded Weatherford International Ltd. (NYSE: WFT) the first global license for the company’s MazeFlo sand control screens for oil wells.
MazeFlo is a patented technology developed by ExxonMobil to improve the reliability of wells completed in sand-prone reservoirs. MazeFlo technology uses redundant screens and a maze of compartments to provide a self-healing capability against sand entering the producing section of a well. Each compartment contains a primary screen, outer housing, flow baffles and a secondary screen. If a primary screen erodes, sand will flow into the affected compartment and accumulate on the secondary screen. Fluid continues to flow to adjacent compartments with undamaged primary screens and can be produced without active involvement from surface operators.
“MazeFlo is one of several openhole sand control completion technologies developed by ExxonMobil during the past few years to address reliability issues in high-cost production wells,” said Sara N. Ortwein, president of Houston-based ExxonMobil Upstream Research Company. “Reliability is very important in deepwater and remote fields where the resource has been developed with high volume wells.”
