N » Pyay Embayment (Pyay sub-basin) is one of the Tertiary sub-basin of the Central Myanmar Basin (CMB) (Bender; 1983, GIAC; 1996-1999, Pivnik et al., 1998).
» CMB is characterized by strike-slip movement of Burma plate against the Shan Plateau along the N-S striking Sagaing Fault (Gross; 1985, Win Swe; 1972).
» N-S running Kabaw Fault delimits the Pyay Embayment from Yakhine Yoma to the west (Win
Swe; 1972, Khan; 2012).
» At the east, the boundary between Pyay Embayment and Bago Yoma, is marked by Central Volcanic Line (Bender; 1983, Pivnik et al., 1998).
» Pyay Embayment and Salin sub-basin are separated by 20° N uplift (Bender; 1983, Pivnik et al.,
1998).
» The Pyay-Aunglan earthquake (1858) indicated as the Pyay thrust is still active since the Plio-Pleistocene
(Chhibber; 1934, Lin Thu Aung; 2014).

» Sharp topography, nearly vertical-overturned bedding, short and straight drainage features are the surface fault traces of Pyay thrust.
» Namayan monocline, Pyay North and Pyay South anticlines are due to the propagating of Pyay thrust.
» Pyay thrust is bifurcated in the Miocene formations and terminated in the southern end of Pyay oil field.
» One of the bifurcated thrust is probably terminated near the formation boundary of the PY and KK formations. The other thrust sheet is terminated as nearly vertical in the PY Fm with no significant displacement.

» Changes in the amplitude of the anticline may preserve profile compression as the thrust displacement decrease towards the south.
» The Pyay thrust geometry is pure thrust features in the Namayan monocline, high angle thrust or reverse fault in the Pyay North anticline and also Pyay South anticline.
» The stratigraphic throws or vertical displacement of thrust are up to ~ 6000 ft in Namayan monocline,

Hydrocarbon Implication» HC occurs in both of supra-thrust (east-flank) and sub-
thrust (west-flank) structure of exposed formations (PY, KK, OB and IRR Fm).
» Source may be Lower Miocene (so-call Pyawbweshale) and can also be the Oligocene age of Okhmintaung Formation (Assuming).
» Commercial accumulation of oil is found in the sub-thrust KK Fm and gas in PY Fm.
» HC bearing sands are trapped by fault bounded closure at the crest and plunge of the anticline and seal by shale layer of OB Fm.

1. The Namayan monocline, Pyay North and Pyay South anticlines are due to the
propagating of west verging major Pyay thrust in the steep west-flank.
2. All three structures have disharmonic features within the Pyawbwe Formation,
double plunging and separated by tow saddles structure.
3. The mean fold axes is trending 346° and the compression form 255°.
4. The area was probably raised (uplifted) to the North, started form the Pyay South
anticline. It is evident by the facts that some HC producing sands (4200‘ of Pyay
South anticline are exposed in the Pyay North anticline, and the whole thickness
of Irrawaddy sediments are absent in the Pyay North anticline.

5. The Pyay thrust is bifurcated and terminated within the Pyawbwe Formation at
the southern end of the Pyay South anticlines.
6. Cross faults are occurred to have formed at least two times of extension before
and after deposition of Irrawaddy formation.
SUGGESTIONS
1. Needs to correlate the surface and subsurface structures (Exposure is very poor).
2. East-flank fault and west-flank faults also need to correlate (continuous or
different faults). If the cross-faults of the two flanks are able to correlate, the
definite timing of deformation on cross-faults and timing of hydrocarbon
migration can be estimated.
3. Stratigraphic correlation between THREE STRUCTURES on east-flank and west-
flank of the are crucial to better understand the reservoir continuity for the future
exploration activities in the studied area.
4. Detailed geochemical analysis of the potential source rocks are also
recommended for the future studies.
