Oilex (ASX:OEX, LON:OEX) has started the production test shut-in period at its Cambay-77H well in India.
Upon completion, the instrumentation deployed downhole will be recovered and the data downloaded for analysis.
The test is focused on acquiring long term performance data essential for assessment of reservoir properties and will supplement surface data collected during flow-back, Oilex added.
A five day shut-in period preceded the test to allow the well to stabilise after around 85 days of flow-back production.
The shut-in is the second part of the formal test process and will comprise at least 300 hours where data will be recorded and monitored.
Oilex intends to announce the successful recovery of the instrumentation and data followed by an announcement regarding the flow-back and test results after a preliminary analysis of the data has been completed.
