Donga-4 appraisal to be cased and suspended
Posted: 15 December 2006
Victoria Petroleum NL has been advised by Bow Energy Limited operator for the Donga-4 oil appraisal well located in the Donga Oil Field in ATP 805P in the Surat-Bowen Basin, Queensland that the ATP 805P Surat-Bowen Basin, Queensland Joint Venture is considering casing and suspending the Donga-4 appraisal well as a future oil producer over the weekend and then releasing the drilling rig ADS Rig 6.
Donga-4 has reached a total depth of 1603 metres and preparing to run wire line logs.
A bottom hole drill stem test (DST) over the Donga sandstone interval 1563 to 1568 metres recovered a minor amount of light sweet crude oil and drilling mud with no formation water present.
The analysis of the DST indicated a combination of drilling fluid influx into the reservoir and blockage during the test is interpreted to have restricted the flow of fluids during the test.
However, the DST also suggests the reservoir is not well developed which is inconsistent with the reservoir interpretation while drilling.
The final casing decision will follow a detailed analysis of the wire line data which are currently being acquired.
The ATP 805P Joint Venture has determined that given the inconsistency of the results of Donga-4, it would not be prudent to drill Donga-5 immediately and the ADS Rig 6 will be released after the work at Donga-4 is completed.
The interests in Donga-4 and ATP 805P are:
- Victoria Petroleum 15%
- Bow Energy 85% (Operator
