Comet Ridge Limited has announced that Easternwell’s Rig 101 spudded the Albany 1 sandstone appraisal well at 1430 hrs on Saturday 19 May 2018. At 0600 hrs on the morning of Monday 21 May 2018, the rig was drilling ahead at 711 m in 12 1/4 in. surface hole and was approaching surface casing point.
The total depth (TD) of the well is estimated to be approximately 2775 m with drilling operations expected to take approximately 25 days. The Albany 1 surface location is 220 m to the southwest of the Carmichael 1 well which was drilled in 1995 and flowed gas at low rates from three intervals.
The drilling of Albany 1 will be the first Phase in the farm-out work programme. Under this program, Vintage Energy Ltd is farming into the sandstone section of the block (the Deeps) by funding the first US$3.35 million of drilling cost for this first well to earn a 15% interest in the Deeps. Vintage can also fund half of the second phase programme which contains further drilling and seismic acquisition in order to acquire a further 15% interest.
The upper sections of the well will be drilled with a standard drilling mud to lubricate the drilling bit and lift rock cuttings out of the well. The lowest (reservoir) section of the well will be drilled with nitrogen. This “underbalance” will allow the gas reservoir section to flow at its full potential without risk of damage from drilling mud.
