Good Practice Guide to Drilling Long Horizontal Wells 2022: Offshore Energies UK (OEUK) Right Scoping Guidelines were produced by the OEUK Wells Forum in 2018. Since then, Well Operators have collaborated in many workshops to review each other’s well design challenges and to select the optimal design for those wells. In 2021 the Work Group identified a requirement to focus on some key themes that would be of benefit to the wider industry. The challenge of drilling long horizontal wells was selected as one of those themes.
A cross-industry workshop was held on 23rd June 2022 with representatives from Well Operators, Regulators, industry groups and the service sector, with the Wells Forum underpinning the attendees. The topic was split into three themes for discussion by separate groups. The themes were: Narrow margin drilling with & without MPD; Wellbore Stability; and Losses Mitigation Techniques. The aim of this brief document is to record the good practices identified by the discussion groups. Many of these themes apply to all wells, but are considered particularly important for the delivery of horizontal wells.
