Whytch Farm Oil Field
Introduction
The oilfield initially was found near the farm called Wytch, in Dorset, south UK in December 1973, that’s why it carries the name Wytch Farm. It’s the largest onshore oilfield in the Europe [Ref 1]. The operator of the field was British Gas Corporation, in 1980s it was sold to BP, in 2011 to Perenco.
Exploration and appraisal
Wytch Farm consists of three reservoirs, which are Frome Formation (800 m), Bridport …show more content…
Map of the Sherwood Sandstone reservoir and Appraisal wells [Ref 1].
The data was gain by exploration wells, laboratory analyses and computer modelling. There’re shown basic rock and fluid properties in the table to give a general imagination.
Development strategy
As the main reserves are located offshore, initially it’s planned to drill a well from artificial island, but assuming the cost, time that would be spent for that, and the effect of the construction to the sensitive environment of the region (it’s popular among tourists), the plan changed and Extended Reach Drilling (ERD) well was decided to drill from the peninsula. It helped to cut the time and the drilling began three years earlier1 comparing with the previous plan. Due to the two main reservoirs (Bridport and Sherwood), the development plan consisted of three stages, first when Sherwood Sandstone reservoir was poor studied, the only Bridport Sands with 6000 barrels of oil per day were under production. After the discovery of oil rich Sherwood reservoir the second development stage (1988 to 1990) began and the production increased ten times. Additionally, the drilling of ERD well (10.5 km length) in 1993, which is third stage, increased the reserves from 30 million barrels to 500 million barrels [Ref …show more content…
In my work I’ve tried to read the interesting me information as much as possible from different sources and compare them, make a common summary and explain in my own words. If the information was from the results of the laboratory or experimental works, or statistical analyses or any other such sources that’s not common known, I showed the references. If the information was common known for a wide range of people or that can be concluded by myself, I used my opinions and
