FX Energy, Inc. announced the start of drilling on the Kutno-2 well in
the Company's 700,000 acre Kutno concession. The Kutno-2 well is planned
to test a large about 35,000 acres 2-D defined Rotliegend structure at a
depth of approximately 6,500 meters.
"FX Energy is pleased to be joined in this project by PGNiG, the most
experienced explorer in Poland," said David Pierce, the Company's CEO.
"Given that Poland currently imports approximately one-third of a Tcf of
gas annually, and the Kutno prospect could have an EUR of up to 9.5
Tcf, both companies recognize that this project has the potential to
change the energy balance in the entire region."
The current rig will be used to drill the first sections of the well
prior to moving Nafta Pila's larger IDM 2000 rig with 500 ton load
capacity onto location for the bottom sections of the well. Drilling is
expected to take approximately eight to nine months. FX Energy is the
operator and will be 50% owner of the Kutno concession; PGNiG will earn
50%.
Plawce-2
The Plawce-2 tight gas well reached total depth of 4,200 meters. Gas shows were encountered as expected throughout the Rotliegend sandstone reservoir.
Cores and logs are currently being analyzed. Based upon the results of
this analysis, the well is expected to be perforated at the deepest
part of the well to determine whether the entire Rotliegend reservoir is water-free. Thereafter, current plans call for perforating and fraccing
approximately 50 meters of Rotliegend in the upper portion of the well
where porosity is approximately 9-10%. After testing, the well is
expected to be completed as a vertical producer.
The Plawce-2 well is located on an uplifted tight Rotliegend block that
could contain as much as 500 Bcf of gas in place within the Fences
concession. The Company holds a non-operating 49% interest in the Fences
concession and the Plawce-2 well; PGNiG operates and holds 51%
interest.
U.S. Alberta Bakken
In Montana, FX Energy is in the early stages of appraising the Alberta
Bakken oil potential in approximately 75,000 net acres. The Company has
drilled and fracced
a vertical well in its Cutbank acreage and is currently monitoring the
flow back. The Company has drilled a second vertical well in another of
its acreage blocks and plans to frac
the vertical section. In three to four weeks the Company plans to
drill a lateral section of approximately 4,000 feet at this location.
Two further wells are planned in the fourth quarter, one vertical and
one with a lateral section, assuming results of the Company's first two
wells meet technical expectations. FX Energy is operator and holds a
one-third working interest in approximately 75,000 net acres; American
Eagle Energy, Inc., and Big Sky Operating, LLC, each own a one-third
working interest.

Gulfsands makes oil discovery in Syria
Gulfsands provided this update on operations in Syria.
BLOCK 26 DRILLING OPERATIONS
YOUSEFIEH EAST EXPLORATION WELL (YOUS-6)
The Yousefieh East exploration well ("Yous-6") has been drilled using the Crosco-E401 rig to test an undrilled structural high in Cretaceous age carbonates located approximately 3 kilometers to the east of the Yousefieh field discovery well (note, this well was erroneously referred to as Yousefieh-8 in a Gulfsands Petroleum plc News Release dated July 11th 2011). The Yous-6 well was deviated at an angle of up to 36 degrees to the vertical in order to avoid obstructions to drilling operations on the surface directly above the target location.
The Yous-6 well encountered oil bearing Cretaceous Massive Formation reservoir at a depth of 2045 meters Measured Depth Below Rotary Table ("m MDBRT") or 1560 meters True Vertical Depth Sub-Sea u("m TVDSS"), 28 meters deep to prognosis. The well penetrated the hydrocarbon bearing Massive reservoir section at an angle of approximately 29 degrees to the vertical. Two twelve meter core sections, parts of which were oil stained, were recovered from the wellbore over the interval 2055-2079m MDBRT (1569-1590m TVDSS). Interpretation of wireline logs indicates a gross porous reservoir interval of 18.1 meters was encountered overlying a non-porous interval, and having a net oil column of 12.8 meters, average porosity of 18% and average oil saturation of 69%.
Pressure data obtained via wireline logs indicates that the oil bearing reservoir is slightly depleted versus initial reservoir conditions, indicating that the Yousefieh East structure is likely to represent an eastern flank extension of the Yousefieh field which is currently on production at approximately 2,600 barrels of oil per day ("bopd"). Reservoir permeability in the Yous-6 net reservoir section is interpreted to be of similar quality to that encountered in the main producing areas of the Yousefieh field.
The Yous-6 well was production tested and produced at an average oil flow rate of approximately 250 bopd of 20 degree API oil for 4 hours on 2 inch choke under nitrogen assisted lift conditions with no water production. The well will be tested further following acidization of the reservoir in a rig-less operation.
Due to a thinner oil column encountered in this well versus other Yousefieh wells, the Yous-6 well will require the installation of permanent artificial lift facilities in order to flow continuously. The Yous-6 well is located within the Yousefieh field Development License Area and can be quickly tied back and produced into the existing Yousefieh field production facilities once artificial lift facilities are secured. Procurement of the relevant equipment is in progress.
The impact of Yous-6 on Yousefieh reserves will be evaluated as part of the year-end reserves review.
SAFA-1 EXPLORATION WELL
Operations have been completed on the Safa-1 exploration well which was drilled using the Crosco M-501 rig. This well targeted a fault-bound dip closed structure of Cretaceous aged reservoir on trend and approximately 7 kilometers north of the Khurbet East Field.
The Safa-1 well is interpreted to have encountered the Cretaceous Shiranish Formation at 1937m MDBRT (1448m TVDSS) and the Cretaceous Massive Formation at 1953m MDBRT (1464m TVDSS). Three consecutive core sections were cut between 1942m and 1975m MDBRT (1453m and 1486m TVDSS), with a total recovery of 31.4 meters of core, sections of which were stained with viscous oil. Evaluation of wireline logs indicates a net reservoir interval of 9.9 meters with an average porosity of 13% and an average oil saturation of 74%.
Well testing operations were conducted in open hole over sections of the gross reservoir column in three stages, however only formation water of low salinity plus traces of viscous oil were recovered to surface, even after an acidification of the net reservoir interval was performed.
The Safa-1 exploration well therefore has been plugged and abandoned as a non-commercial heavy oil discovery.
FORWARD DRILLING PROGRAM
Gulfsands drilling operations in Syria Block 26, using the Crosco E-401 and M-501 drilling rigs, will continue as planned with the drilling of one development and one exploration well.
The Khurbet East-20 well is planned as a delineation well to further evaluate the northern flank of the Khurbet East field. The Wardieh-1 exploration well will target a new exploration play, a combined structural/ stratigraphic trap located on the southern flank of the Souedieh Field at the Cretaceous "Massive" level.
BLOCK 26 OIL PRODUCTION
Production operations on Block 26 continue without interruption. Combined gross oil production from the Khurbet East and Yousefieh fields has averaged in excess of 24,000 bopd to date during the month of August following commissioning of an additional Khurbet East sub-station facility on August 6, 2011.

Roc Oil Announces appraisal drilling success
Roc Oil (Bohai) Company, a wholly owned subsidiary of ROC, reported
that production has commenced from the first appraisal well drilled in
the new Zhanghai block—one of two adjoining blocks added to ROC’s
existing Zhao Dong Block contract in March 2011 with the aim of
commercializing previous near-field discoveries in the area and
encouraging further appraisal activity.
The appraisal well (ZD CP2N-H-1) commenced drilling from the Zhao Dong C4 platform on 15 July and intersected 310 m of horizontal reservoir section. The well was completed, and production through existing C4 facilities has commenced at an initial rate of 3,546 bopd. PetroChina exercised its rights under the PSC to participate with a 51% interest in the new Zhao Dong blocks on the commencement of completion activities and commercial development of the well, effective Aug. 12. The interests in the two new additional blocks are now PetroChina 51%, ROC 39.2% and Sinochem 9.8%.
The company is planning to drill a second appraisal well during 2012.
Commenting on the success of the well, ROC’s CEO, Alan Linn, stated:
"One element of ROC’s strategy is to generate future growth by commercializing near field opportunities through existing infrastructure. Extension of the Zhao Dong block provides an opportunity to incrementally develop a number of existing discoveries through existing Zhao Dong facilities in parallel with ongoing development drilling activities. Exploration opportunities within this acreage could also impact the future profitability and recovery life of the existing assets.
Production from the first appraisal well in the additional Zhao Dong blocks is a positive outcome for all joint venture partners and represents the achievement of another of ROC’s key strategic objectives for 2011: to deliver a new production or pre-development opportunity in China."
