day 77 of 90 for BD260 Rig22 Aug 2018 10:03
As we are expecting this rig any day- "hopefully" and we will have it for six months, this is a recap of what it should be doing....
The BD-260 rig will complete the workover of Z-21 by pulling out the entire tubing string from the well, cleaning out the casing to the well's total depth, 3,982 metres, and subsequently performing a number of production tests. In the event that a satisfactory rate of production was not to be achieved from Z-21 following these operations, the Company would proceed with deepening well Z-21 beyond the Maykop formation into the Eocene and Upper Cretaceous formations by drilling an additional 300 metres, extending the well's total depth to approximately 4,270-4,300 metres. The primary reason for the evaluation of this possibility is the proximity of Z-21 to well Z-3, spud in 1979 and drilled to a total depth of 4,300 metres into the Eocene and Upper Cretaceous formations. Z-3 tested approximately 2,900 barrels of mixed hydrocarbons per day before the wellbore collapsed.
Â
Following the completion of operations in well Z-21, the Company will move the BD-260 rig to Z-28, where 69 metres of tubing require milling out before the well is cleaned out to its total depth, 3,944 metres. Zenith will perform a number of production tests once the well has been cleaned out to total depth.
Â
After the completion of operations in well Z-28, the Company intends to use the BD-260 rig for the workover of Z-3, where historical records indicate that 775 metres of tubing has been left in the well, and for the workover of MOC-1 in the Muradkhanli field. Zenith will further update the market in greater detail regarding these planned operations once the workovers of Z-21 and Z-28 have been completed.
