Ann: Drilling commences at Mukuyu-2 Appraisal Well, page-251

No more leaky than any drilling project. IVZ employees and all service people and consultants are usually under information confidentiality agreements with IVZ. Employees and consultants who leak data from a rig generally don't stay in their jobs for long. Rig and camp crews.....a few of them are usually playing the market but you're talking small potatoes.

Mobile phone reception won't be crash hot where the rig is and primary comms will most likely be via satellite link. Sat links make it easy to track phone calls and where people are surfing on the net. Not hard to track down a major leak and deal with the culprit.
