Since the last report on the 4 th of March 2024, the well was drilled to depth of 930 metres in 12 ¼ inch hole,wireline logs have been run, 9 ⅝ inch casing has been run then cemented and the well drilled in 8 ½ inch holeto the current depth of 1028 metres.
Well penetration rates have been faster than projected and the well is about 4 days ahead of theoriginal well plan
Minor hydrocarbon shows have been encountered in the carbonate formations. Formation gas shows haveincreased from 0.0099% to 0.1765% primarily for methane as well as ethane and propane also measured uponentering the Lunz Formation where the 9 ⅝ inch casing has been se
Formation gas is gas that is entrained in the drilling fluid during the tripping of drill pipe (pulling pipe out of thehole). Formation gas is not expected to be producible from the shallow carbonate or Lunz formations, howeverthe formation gas is evidence of an active petroleum system at the Welchau-1 well location that may result in aproducible gas zone deeper in the well where the target reservoirs are expected to be encountered.
The planned forward program is to drill ahead in 8 ½ inch hole to the main target.
