The Key Excitement Was Gas Kicks (Further Discussion On “…overbalanced mud weight”)
・ The drill was using 10 lb. of mud pressure through to the Endrod formation, but once that formation was reached the gas pressures were so intense that it was becoming hard to contain.
・ Mud pressures were increased to 12 lb.; despite this gas kicks continue to break-through the mud. This is concrete evidence that gas is present and that it is highly overpressured.
・ Although this does not prove that the gas reservoir is economic (the well still needs to be test and fracked), it is an indicative sign that the reservoir likely contains a substantial amount of gas.
Implications Of This Early Result:
Again, the Pusztaszer-1 well is 45 km from the “main” target well (Mako-6), which is currently drilling (started about 3 weeks prior to the Pusztaszer-1 well). If the reservoir proves to be fully charged it will lend credence on the theory that the entire Mako Trough BCGA contains more than
100 tcf of gas in place.
