GODALMING, UK – Hurricane Energy is considering options for next-phase development drilling on the basement Lancaster oil field west of Shetland.
Last December the company was assessing a potential side tracking from the existing 205/21a-7z well into the central area of the field.
However, this would be more complex to drill than previous wells on Lancaster due to the need to incorporate an intelligent completion, and the well trajectory from the side track location.
Drilling during the 2021 summer weather window would entail operational and cost risk. Other options could be to defer the side track to 2022 following further planning work this year; to drill the side track with a planned water injector under a combined campaign again in 2022; or to pursue the side track in 2022 and the water injector in 2023.
Other unknowns which could influence thinking are field performance, prevailing oil prices, and support from stakeholders and counterparties.
Hurricane’s phased development of Lancaster started with an early production system comprising two wells tied-back to the FPSO Aoka Mizu. First oil flowed in June 2019.
