Oil and Gas Sands Test in St. Martin Parish, Louisiana
Termo is partnered with Penta Resources of Lafayette, Louisiana in the Bull Moose Prospect to test the reserve potential of the Marg Tex 2, Stuart A and Bol Mex 2 sands. The well has a proposed TVD of 11,500’ and is located on the north flank of the Section 28 Field. In adjacent fault blocks are the Amoco St. Martin Land #9 and Stanolind St. Martin Land #5 wells. The Amoco #9 has produced 1.19 BCF and 1,100 MBO and the Stanolind #5 has produced 5.90 BCF and 580 MBO. The fault trap is bounded laterally by faults “R” and “S” and updip by Superior St. Martin Land #B-1 and Cypress Stuart #1 with gas pay in the Bol Mex 2A sand. Control for the faulting and salt placement is from reprocessed 3-D seismic data and subsurface well control.
The wells penetrated the Marg Tex sands up-dip from the apparent pay zone in the Amoco SML #20 well. In the up-thrown fault block, the Amoco SML #21 well is actively producing from the Marg Tex 2A sand. Downthrown on Fault T is the Amoco St. Martin Land #16 which is actively producing the Marg Tex 2A sand. In the fault block to the east and on strike, the Amoco St. Martin Land #7, #14 and #19 wells are productive in the Marg Tex 2 sand with cumulative production of 144 MBO and 208 MMCF.
Two cases were run with three sands productive by virtue of the down-dip or adjacent production, a likely case with the Marg Tex 2 having 48 MBO, and 144 MMCF, the Stuart sand having 100 MBO and 250 MMCF and the Bol Mex 2 having 412 MBO and 889 MMCF for total potential reserves of 312 MBO and 639 MMCF. An upside reserve estimate calculated for all three sands is 544 MBO and 1,582 MMCF. The proposed 11,500’ well is estimated to cost $1.2 million dry hole or $2.4 million dry hole if a liner over the Het sand is required. The completed well would cost an additional $720,000 or $1.92 million for a completed well if the liner is not required.
