FX Energy, Inc. has completed the flow portion of the dynamic reservoir test on the Tuchola-4K well located on its Edge license in north central Poland, where the company holds 100% working interest, the company reported in a news release. The well produced at a steady rate of approximately 15 million cubic feet of gas per day (Mmcf/d) and flared a total of 60 Mmcf over a four day period. The flow rate and the flowing wellhead pressure both increased over the first 24 hours of testing and then remained constant through the end of the flow period. The well was then shut in to allow the bottom hole pressure to stabilize and will remain shut in until 8am central European time Monday, May 26, when the bottom hole pressure gauges will be retrieved. The bottom hole pressure data, together with the gas flow data, will be used to estimate the total gas in place and the recoverable gas in the well. That information will be released as soon as available next week. The pressure gauges in the Tuchola-3K well will also be retrieved and should reveal whether the two wells produce from the same or different reservoirs.
"The Tuchola-4K well performed beautifully, with flowing volume and flowing wellhead pressure remaining essentially flat throughout," said David Pierce, CEO of FX Energy. "If the bottom hole pressures are comparably strong, we will have a very nice well indeed. At this point the well is providing great support for our decision to proceed promptly to development and to expedite further exploration efforts in the area."
The Company reported that the Szymanowice-1 sidetrack tested gas initially but watered out after several days and now will be plugged. Szymanowice-1 is located in the Lisewo area of the Fences license. It was completed initially in December 2013 as a vertical well in a 33.5 meter section of Rotliegend sandstone reservoir rock. At year-end 2013 proved reserves were 3.9 Bcf with a present value of $4.1 million, net to the Company from this well. Low production rates on testing were determined to be due to anhydrite cementation in the upper portion of the reservoir. It was hoped the sidetrack would reach a less impaired area of the reservoir at some distance from the original bottom-hole location. The problems at Szymanowice-1 may be related to more intense fracturing than is usually encountered in Fences wells, or to some other factors. Company technical personnel, along with the Operator's technical group, are investigating the matter in detail.
In other Fences operations the Company noted that drill-site preparations remain underway on the Baraniec well in the Lisewo area of the Fences license. Drilling operations are expected to begin later in June. Drilling is expected to start on the nearby Ciemierow well, also in the Lisewo area, after rig release on the Baraniec well. The Karmin well, near the southeast boundary of the Fences license, is expected to start drilling in about two to three months. The Karmin location
