ExxonMobil Corp.'s Yellowtail development offshore Guyana has advanced with installation of the first water alternating gas injection (WAG) jumpers.
Strohm fabricated the first 13 thermoplastic composite pipe (TCP) jumpers as part of its jumper on demand concept. The first two TCP Jumpers were integrated with vertical connections, pressure tested, and installed subsea at depths of more than 1,700 m earlier this month. The jumpers, installed by spreader bar, were locked in and back seal tested, the manufacturer said in a release Aug. 1.
"This first Jumper on Demand campaign for ExxonMobil applies a high-volume fabrication method, proving that onsite fabrication of TCP jumpers has the flexibility to scale up or down as the installation schedule demands," said Gavin Leiper, vice-president Americas & Global Field Services Group, Strohm.
Leiper said the company will collaborate with ExxonMobil during the next fabrication campaign in 2026.
Production from the Yellowtail project in the Stabroek block is expected to start late-2025 following completion of installation and well activities, bringing daily production capacity across ExxonMobi Guyana operations to about 900,000 bbl (OGJ Online, Apr. 17, 2025).
ExxonMobil Guyana is operator of the block with 45% interest. Partners are Chevron (30%) and CNOOC Petroleum Guyana Ltd. (25%).
