Previous information from the October 16 Annual Report was for a program of five wells: -
"A successful production test will provide the catalyst for a potential pilot development project and provide data which will enable Oilex to increase production and cash flow while confirming the commercial potential of the Cambay “tight” X and Y Zone reservoirs. The contingent drilling campaign of three vertical and two horizontal wells and a pilot development project will also provide data to support converting Contingent Resources into Reserves. Importantly Oilex has an Oil Sales Agreement in place and a refinery exists nearby."
I assume one or two of the vertical wells will be exploration to the deeper to the Decan formation (one vertical well would be to prove up X and Y Contingent Rescources). Its only a guess but I imagine that Oilex would have ordered the long lead items for 5 wells already once Cambay 77H started flowing good oil at a decent pressure. The usual plan would be to drill and move the rig onto the next well with the testing equipment following behind the rig onto the completed wells - and keep doing this. The before mentioned smaller diameter production casing would be inherently of a higher pressure rating and maybe readily available as an ex stock item - so once the rig contract is awarded Oilex could be continously busy drilling, stimulating, testing - and more importantly making oil and gas sales during 2015.
