Following a shut-in period for pressure build-up, the uppermost zone (1,680 to 1,710 meters) produced a maximum stabilized flow rate of approximately 3,650 barrels of oil per day (bopd) of 18.6 degrees API oil through a 1’ choke. This follows Tullow’s previous update reporting that the same zone flowed at a stabilized rate of approximately 2,100 bopd through a 36/64' choke.
According to Tullow, the Waraga-1 testing program has concluded. The well tests were designed to assess formation productivity and acquire good-quality fluid samples. The well has been plugged and suspended, ready for completion and potential future production.
The rig and testing equipment will now be relocated to the Mputa-1 location for flow testing of similar oil-bearing intervals to those tested at Waraga. In addition, a flow test will be attempted from fractured basement lithologies where hydrocarbons were encountered during the drilling of the Mputa well--an additional play type to those already tested at Waraga. The program at Mputa is expected to commence in early August.
Hardman's next drilling update will be later this month with the spudding of the Colin-1 well, located in PSC Area “A,” offshore Mauritania.
