TransAtlantic Petroleum Provides Operational Update

HAMILTON, Bermuda, Oct. 1, 2013 (GLOBE NEWSWIRE) -- TransAtlantic Petroleum
Ltd. (TSX:TNP) (NYSE-MKT:TAT) (the "Company" or "TransAtlantic") today
provided an operational update on its current drilling program.

Operational Update

TransAtlantic ended the third quarter of 2013 with production of more than
4,500 Boe/d and expects its 2013 year-end exit rate to be at least 5,000
Boe/d. The Company currently has three active rigs in southeastern Turkey and
two active rigs in the Thrace Basin in northwestern Turkey. In the fourth
quarter of 2013, TransAtlantic expects to add one drilling rig in Bulgaria and
release one drilling rig in the Thrace Basin in Turkey to maintain a five rig
operation going forward. The Company spudded 18 wells in the third quarter of
2013 and 27 wells year-to-date. TransAtlantic plans to drill a total of 38
wells in 2013.

Southeastern Turkey – Şelmo Field Redevelopment

TransAtlantic recently drilled a horizontal well in the Şelmo field (100%
working interest) targeting the MSD zone at a depth of approximately 5,200
feet for $2.2 million. The Company is currently drilling a second horizontal
MSD well and will complete both wells in October 2013. TransAtlantic plans to
drill two to five additional Şelmo horizontal wells targeting the MSD zone in
the fourth quarter of 2013.

Based on the success of the Şelmo-13H horizontal well, which targeted the LSD
zone at a depth of approximately 6,000 feet and is currently producing more
than 300 Bbls/d of oil, TransAtlantic expects to drill two additional Şelmo
horizontal wells targeting the LSD zone in the fourth quarter of 2013.

Southeastern Turkey – Molla Drilling Program

In August 2013, TransAtlantic drilled the Göksu-5H horizontal well (100%
working interest) to the Mardin zone at a total measured depth of 5,400 feet
for a cost of $2.8 million. The Company has five horizontal wells in
southeastern Turkey awaiting completion with a coiled tubing unit including
the Göksu-5H, Alibey-1, Oba-1 and two Şelmo wells. TransAtlantic expects to
complete and test these wells in the fourth quarter of 2013.

The Company is currently drilling two exploration wells in the Molla Area. The
Tepe-1 (100% working interest) has a targeted depth of 9,500 feet in the
Mardin and Bedinan formations on an exploration license the Company acquired
in May 2013. The Ambarcik-2 (50% working interest) has a planned total depth
of 9,750 feet targeting the Bedinan formation in the Arpatepe license. The
Company expects to drill at least one vertical well in the Arpatepe field (50%
interest) in the fourth quarter of 2013.

TransAtlantic continues to make progress on its 800 square kilometer (300
square mile) 3D seismic program over Molla and the surrounding areas. To date,
approximately 365 square kilometers (140 square miles) have been shot and the
data is being processed in Dallas, Texas. A detailed map of the Molla 3D
seismic program is available on TransAtlantic's website at
http://www.transatlanticpetroleum.com/news.aspx.

Northwestern Turkey – Thrace Basin Development

TransAtlantic completed and is currently production testing the BTD-4H (41.5%
working interest), its second horizontal well in the southern Thrace Basin.
The well cost $3.3 million to drill to a total depth of 5,800 feet and
features a 2,100-foot lateral section within a porous and permeable
gas-bearing member of the Teslimkoy formation.

In the central Thrace Basin, TransAtlantic drilled the Karanfiltepe-5 (41.5%
working interest) in the third quarter of 2013 and is currently running logs
to identify completion targets to test for the presence of hydrocarbons. An
offset well, the Karanfiltepe-4 (41.5% working interest) continues to produce
2.5 MMcf/d. The Company also spudded the Yildirim-3 in September 2013,
targeting the Osmancık formation at a depth of 4,500 feet.

In the northern Thrace Basin, the Company drilled six shallow, vertical
natural gas wells in the Edirne field after negotiating a low cost, group rate
drilling and completion package in the third quarter of 2013. One well was a
dry hole and five wells will be completed in the fourth quarter of 2013.

The Company began a 234 square kilometer (90 square mile) 3D seismic program
in the Osmanlı area of the southern Thrace Basin. A detailed map of the
Osmanlı 3D seismic program is available on TransAtlantic's website at
http://www.transatlanticpetroleum.com/news.aspx.

Bulgaria

TransAtlantic expects to spud the Deventci-R2 (50% working interest) in
October 2013, which will be a directional exploration well targeting the Dolni
Lukovit zone at a depth of approximately 14,500 feet. The Company's joint
venture partner will assume 75% of TransAtlantic's initial $40 million work
program in Bulgaria.

Third Quarter 2013 Earnings Call

The Company will provide more detailed operational and financial results on
its third quarter 2013 earnings call, which it expects to host in the first

Note on Boe

Barrels of oil equivalent, or Boe, are derived by the Company by converting
natural gas to oil in the ratio of six thousand cubic feet ("Mcf") of natural
gas to one bbl of oil. A Boe conversion ratio of 6 Mcf to 1 bbl is based on an
energy equivalency conversion method primarily applicable at the burner tip
and does not represent a value equivalency at the wellhead. Boe may be
misleading, particularly if used in isolation.
