LONDON (Alliance News) - Caspian Sunrise PLC said Wednesday that it has drilled drilled 75 metres of its four intervals at Deep Well 801.
The four intervals, which are potentially oil-bearing, were discovered while drilling a side-track. Caspian intends to acidize the intervals and has moved to low-density drilling fluids in order to prepare.
The acidization should clean any damage caused by the drilling process and make the oil reservoir more permeable.
During acidation, acid is pumped into the well, dissolving limestone and other rocks and making the oil easier to extract.
Shares in Caspian Sunrise were down 5.8% at 9.91 pence on Wednesday.
