FX Energy, Inc. reported that it has drilled and cored a 118-foot (36-meter) section of Main Dolomite in the Tuchola-3K well. The Main Dolomite is the first of two target zones in this well. Very good gas shows were observed throughout the entire 118-foot section, but the drill stem test (DST) of the Main Dolomite from 8,665 to 8,783 feet (2,641 to 2,677 meters) did not encounter any inflow of gas or fluid. Core samples confirm that the Main Dolomite is tight and the fractures are cemented with anhydrite. Drilling will continue on the Tuchola-3K well to test a projected Devonian oil target at a depth of 10,433 to 12,533 feet (3,180 to 3,820 meters).
"The Main Dolomite is present as mapped and charged with gas as we had expected," said Vice President of International Exploration Jerzy Maciolek. "The problem we have encountered in the Tuchola-3K well, as with other Main Dolomite fields in Poland, is that reservoir quality is capricious: portions of the reservoir are cemented while other portions are quite porous and permeable. Clearly the Main Dolomite is gas charged and a nearby area with better reservoir properties should yield favorable results."
"We will use the data from this wellbore to calibrate our existing seismic for the direct detection of porous dolomite," continued Maciolek. "If we can detect good reservoir quality nearby in this reef trend, we would like to test it as soon as possible. This could be done by a sidetrack from the Tuchola-3K wellbore itself, if the deeper Devonian oil target is not successful. Alternatively, we could schedule a new well to test the Main Dolomite nearby. We are encouraged about Main Dolomite gas potential in the Tuchola concession and plan to increase our exploration efforts in this target area."
The Tuchola-3K well is located on one of four blocks that comprise the 880,000 acre Edge concession area in northern Poland. FX Energy holds a 100 percent interest and operates the Tuchola-3K well and the Edge concession area.
The Company also reported that the Mieczewo-1K exploration well is currently drilling below 9,843 feet (3,000 meters). The well is a planned test of a Rotliegend structure at a projected depth of 11,024 feet (3,360 meters). The Mieczewo-1K well is located in the western part of the 850,000 acre Fences concession, where PGNiG is the owner of the concession and operator and holds a 51% interest, the Company holds a 49% interest.
