A systematic approach, including better planning and performance evaluation, improved the horizontal drilling efficiency of a multiwell program in the Oseberg field in the North Sea. The horizontal drilling program in the Oseberg field is one of the most comprehensive horizontal drilling programs in the North Sea. The present horizontal drilling program consists of 14 oil producers from the C platform and 18 from the B platform. Total horizontal displacement varies from around 1,500 m to 5,540 m. The lengths of the horizontal section vary from 600 m to 1,500 m. The paper discusses will planning, directional drilling, drilling problems with coal seams and orientation, true vertical depth control, horizontal liner cement, spacer system, cement slurries, job execution, and results.
