1. INTRODUCTION

The following sections contain activity lists for the planning phase and scheduling phase, as described

in the previous chapter. They should be seen as guidelines that could be used as a starting point for

setting up a well construction project. Activities not applicable to the specific well construction projectcan be deleted for the specific activity plan.

The lists can be used to assign staff to activities and thus maintain a project management type of

control on the progression of the well construction project.

2. REQUIREMENTS

In order for these lists to be up to date and to reflect the latest lessons learned, the Drilling

Superintendent shall ensure that the electronic versions are being updated after conclusion of every

well construction project.
