Of all the energy companies providing updates this morning, only Winchester Energy (ASX:WEL) stood out because it recovered significant oil.

The Texas-focused explorer has swabbed two intervals at its Arledge 16#2 well and the combined rate is 80 barrels of oil per day. Shares jumped nearly 20 per cent at market open.

The company called these results highly significant and reminded shareholders two intervals were yet to be tested. It not only believes more oil is present within these intervals but that these are more prospective.

Winchester attributed its higher sand content, superior wireline and mudlog response and its greater thickness to its beliefs that more oil is present.

But for now the two intervals that were tested will suffice as its cause for optimism. The first interval swabbed 100 per cent oil with an entry rate of 30-35 barrels of oil per day. The second, swabbed 80 per cent oil at 48 barrels per day.

The company conducted a $2.5m placement earlier in the month and also owns another oil field in the Permian basin – the Mustang field.

One well there, White Hat 20#3, is producing over 200 barrels of oil per day and Winchester is testing a second well (White Hat 20#5).

Winchester shares climbed 18 per cent at market open this morning.
