The company said that the workover was undertaken to improve production flow rate and provide the ability to chemically treat the well downhole. It is anticipated this work will aid in future well flow performance.
The work necessary to achieve this increase in oil production involved pulling the production completion tubing string out of the well, changing components of the downhole equipment, installing wax scrappers onto the rod string and adding a chemical injection conductor line that will allow the periodic dosing of specialized flow improvement chemicals over the life of the well.
The well was taken offline to undertake this work thereby curtailing field production, however, the company took the decision to perform this important improvement work now before commencing the drilling of its planned Lidsey #2 well. This was done to take advantage of an equipment and personnel opportunity window.
The company also based their decision on industry views and financial predictions that the price of oil will remain close to or above $80 per barrel during 2010. The company feels that by undertaking this work now it will benefit from sustained cash flows during the drilling phase of the Lidsey #2 well when its nearby Lidsey #1 well’s production is expected to be impacted due to operational activities in its vicinity requiring it to be temporarily closed in.
Key Petroleum is undertaking a number of changes at it’s UK oilfields designed to specifically improve oil production and subsequently sales of produced oil.
Ken Russell, managing director/CEO of Key Petroleum, said: “The results being seen at this time from our Brockham well following this workover, indicates to us that with some thought and planning we can continue to improve production and operations of our UK assets.
“We plan to build on this successful result as we move forward towards our Lidsey #2 drilling program, currently being developed and planned to commence in the coming months, once necessary regulatory approvals have been received.”
