RE: Mengo vs Djeno5 Jul 2019 10:23
When they reported the oil leaking they made it all sound very upbeat and promising but actually I don't see how they can ignore a cement plug thats fractured and leaking under pressure.
This is why I think they have to deal with the Djeno before attempting to work on the mengo or any other section.
Environmentally alone it has to be a must surely?
After several weeks of settling, and unexpectedly, pressure began to rise at the well head. In order to manage this pressure, the well was bled off and, during this bleed, oil was produced at surface along with gas and water. Following this initial bleed, the well has been bled weekly in order to manage pressure. Over this period, the well has continued to produce oil and gas, and the water content has subsided. The well now flows without any assistance for the entire duration of the bleed without a drop in its flow.
The oil has been collected and then tested by both the Total laboratory in Pointe Noire and the Congolese state refinery. Both tests show an oil quality of 43 API; due to the characteristics of the oil and the well design, it is calculated that this oil is from the Djeno reservoir, leaking to surface under associated gas pressure through a fracture in the concrete plug.
This welcome news has confirmed the potential of the Djeno reservoir in our block. As a result, the Company has taken the decision to target the Djeno for production from TLP-103C.
