In 1990 PDO awarded the world1! biggest Turnkey Drilling Contract with a scope of work for 112 wells for the development of the Lekhwair field. An option to drill an additional 56 wells was included.

This paper gives an overview of the strategy and objectives that led to the award of this Turnkey Contract.

The Lekhwair Turnkey Contract, which covers a large number of wells, was supported by the preparatory work of a Multi-Discipline task force. The team, consisted of staff from Drilling Engineering, Production Engineering as well as Petroleum Engineering. The main issues addressed by the task force were: to agree on the well designs in relation to the field development concept and to formulate the basic input for the scope of work for a Turnkey type Drilling Contract

The paper discusses the Management principles for Turnkey Drilling Operations whereby the focus is given to Management of the Turnkey Contract, Quality of the Product, Health, Safety and Environment (HSE) issues and the Performance of the Turnkey Contractor.
