LONDON -- Ithaca Energy has started operating the downhole pump on the Jacky field, increasing gross production rates to approximately 10,000 b/d of oil.
The Jacky field came onstream on April 6, at initial rates of approximately 8,800 b/d of oil. Downhole pressures and deliverability were above the company's expectations and as a result the activation of the downhole pump was delayed.
Average production in April and May from Jacky and Beatrice (Bravo and Alpha facilities) was lower than the initial rates experienced due to the fall in downhole pressure from Jacky; constraints from ongoing commissioning and well maintenance work at Beatrice; and a portion of initial Jacky production contributing to fill the infield and export pipelines.
In April, the average Jacky and Beatrice volumes arriving at the Nigg Oil Terminal were 4,740 b/d of oil. In May, prior to switching on the downhole pump at Jacky, production from Jacky and Beatrice was approximately 5,390 b/d of oil. These numbers compare with expectations prior to Jacky field startup (7,500 b/d of oil), the company says.
Commissioning and maintenance work is now finishing and the Beatrice and Jacky facilities are currently producing at combined rates of approximately 11,500 b/d of oil and will quickly make up the production deficit from April and May.
Partners in the Jacky field are Ithaca (67.275%), Dyas UK (22.725%), and North Sea Energy (UK) (10%).
