Summary Information
* Operator: E-On
* Country: UK
* Location: Block 43/27a, Southern part of the North Sea
* Production start:
* Partners: Dana Petroleum
* Type: Gas
* Estimated Reserves:
* Production Volume:

+++ Description
* The Johnston Field is located 85km north-east of Easington in the Sole Pit sub-basin of the Southern Gas Basin in approximately 39 m depth of water
* Gas is transported to the [[Easington Gas Processing Terminal]]

+++ Contractors
* **Technip:** Project management, design and installation of a 6.7km flexible flowline and 6.7km control umbilical, as well as complete all associated tie-ins and testing and pre-commissioning works
* **Bibby Offshore:** Johnston tie-ins
* **Seaway Heavy Lifting:** T & I - Johnston Wellhead Structure & Johnston Template

+++ History

* 1993 - Development approval given
* 1998 - Centrica acquires a stake from Powergen
* 2005 - Technip awarded pipeline contract
* 2005 - Eon acquires the field in the Caledonia deal

+++ Geology
* The field has a structural trap, fault bounded to the SW and dip-closed to the north, east and south. This field geometry has been established using high quality 3D seismic data, enhanced by seismic attribute analysis. The sandstone reservoir interval consists of the Early Permian, Lower Leman Sandstone Formation of the Upper Rotliegend Group. This reservoir consists of a series of interbedded aeolian dune, fluvial, and clastic sabkha lithofacies. The quality of the reservoir is variable and is principally controlled by the distribution of the various lithofacies. The top seal and fault bounding side seal are provided by the overlying clay stone of the Silverpit Shale Formation and the evaporite dominated Zechstein Supergroup.
