A drilling break
(an increase in the rate of penetration) was recorded from 13,196 to 13,267 feet measured depth.
After the winter drilling break
, current plans are to drill the Salcia prospect, another plunging anticline in the same area as the Lapos prospect with unrisked potential of 7 to 25 MMBOE.
E[acute accent]On this basis, Phase I will take some 11 weeks to complete including a drilling break
over Christmas with a Phase II Program of 125 core holes to then begin on receipt of Saskatchewan government approval.
At the conclusion of the current program, a brief drilling break
at TZ will be used to consolidate and organize drilling data and initiate an economic scoping study of the project.
Surface exploration work will be ongoing during the drilling break
to develop Sector Zeta and other targets to the drilling stage.
A drilling break
at a depth of 13,219 feet (4,029 meters) encountered sands that contained hydrocarbon shows and flowed free oil and gas to the surface with the well flaring excess hydrocarbons while well control measures were implemented to continue drilling operations.
A 14 meter drilling break
was encountered at the top of the Eocene Tasaran horizon at 643 meters and continued to 657 meters.
The target objective in the Wilcox has been encountered over significantly larger intervals than originally anticipated and has given multiple extensive hydrocarbon shows which occurred during fast drilling breaks
, and resulted in gas-cut mud weights, gas to the surface, condensate in the mud, and included pressures higher than anticipated.
Russell Porter, Gastar's President and CEO, commented, "We are encouraged since the Donelson #4 encountered several strong drilling breaks
and gas shows in the targeted lower Bossier formations.
These gas shows and limited drilling breaks
while drilling indicated that the Granite Wash interval is less developed in the far north west of the field than elsewhere in the field.
Continuous drilling followed with five drilling breaks
which allowed the Company to conduct core sample and drill stem tests to evaluate potential producing zones.
Permitted as a Newark East Field Barnett test, the Boggs #1 encountered significant drilling breaks
and mudlog shows in the Ouachita Section.
