Introduction

Insert introductory paragraph outlining a brief description of the project, referencing the field, the subsea infrastructure to be installed, as per example in blue.

In accordance with the Petroleum Act 1998 and under the Guidance of the Oil and Gas Authority guidance notes (Company Name of PWA Holder) apply for authorisation to construct and use a 7” Production Pipeline, 3” NB gas lift flowline, Controls umbilical pipeline, 6” production jumper, 3” gas lift jumper and Control jumpers.

Administrative Details

2.1 Overview - Description and diagram of project

Insert a brief description of the project, why it is needed (see example in blue). Provide an overall project layout diagram showing pipeline(s) to be covered by the Authorisation and route of the pipeline(s) see below drawing.

For the purposes of this PWA application the scope of the (Field Name) Development pipelines system is as follows;

• 7” NB production flowline

• 3” NB gas lift flowline

• Controls umbilical pipeline

In addition, short well rigid jumpers and control jumpers will be required:

• 6” production jumper

• 3” gas lift jumper

• Control jumpers

The (Field Name) reservoir will be initially developed using a single production well. This well was drilled in mid YYYY to appraise the discovery and was completed as a production well with the wellhead installed and suspended in anticipation of production in January YYYY. A second well may be drilled to develop upside in the area, contingent on the performance of the first. Production wells will be gas lifted. The reservoir will require water injection for pressure maintenance. The design and location of the water injection well and flowline are currently being considered and will be subject of a variation to this PWA once the detail is finalised. Nonetheless, provision for a water injection well has been included in the initial facilities design.
