OVERVIEW OF THE POTENTIAL OF TIEN HAI GAS
FIELD FOR EGR
1. Geographical location
Tien Hai Gas Field is situated in Tien Hai district, Thai Binh province, about
100 km away from southeast Hanoi. This field belongs to the Khoai Chau- Tien
Hai uplift zone, which is the most potential gas and oil area in the Red River
Delta Basin.

Delta basin
2. Exploration and production history
The history of exploration activities in Tien Hai Gas Field is coupled with
those in the Red River Delta basin. In the area, 228 km-length of seismic
measurements, and 21 exploration and exploitation wells have been carried out.
On the 19 April 1981, the first 100,000 m3 gas were produced from the
well 61 and used for thermoelectric turbine. In the next years, a series of
production wells were drilled and 14 gas-bearing layers have been discovered
with a estimated total of 1.3 billion m3 gas.
Since 1981 up to now, a total of 850 million m3 gas has been produced
and used for power generation, and production of cement, brick, porcelain and
glasses, etc... in Tien Hai Industrial Zone.
At present, the Tien Hai Gas Field has been being depleted, therefore it is
probably the subject for EGR.
3. Structural geology
The Tien Hai Gas Field is a Miocene-aged inverted uplift zone, which is
structurally closed on both sides by 2 reverse fault systems, namely Vinh Ninh
and Tien Hai Faults (Figures 2-3).

Tien Hai Gas Field
The Tien Hai Gas Field includes 14 gas-bearing layers numbered from T0
to T13, which are aged from Middle Miocene to Late Miocene. The reservoir is
composed of delta-facies sandstone layers, interbedded or overlied by thick
marine-facies claystone and marsh-facies mudstone layers (acting as aquicludes)
in domal structures. These gas-bearing sandstone layers are distributed from 460
to 1,700 meter depth, mainly belonging to Upper Phu Cu, Lower and Middle
Tien Hung Sub-formations (Figure 4).

4. Potential for CO2 geological storage
Among the gas-bearing layers, the layers from T4 to T8 are of good quality
and contain almost all the gas volume of the Tien Hai Gas Mine. These layers
are distributed from 850 to 1,200 meter depth (Figure 5), and the porosity of
sandstone ranges from 10 to 24%, mainly in the interval from 13 to 20%, and
the permeability ranges from 1 to 500 mD, mainly from 3 to 70 mD (Figure 6).
At present, these gas-bearing layers have been being depleted and flooded,
therefore they are considered to be suitable for EGR.

The theoretical capacity of Tien Hai Gas Field for CO2 storage was
calculated as follows:
MCO2 = ρCO2r× A × h × φ× (1 – Sw) ×B
Where, A, h, φ and Sw are the area, thickness, porosity and water
saturation of the reservoir; B is the factor which converts from the gas volume at
standard condition to the gas volume in place; ρCO2r is the density of CO2 in the
reservoir (ρCO2r = 0,7 ton/m3).
The theoretical capacity of Tien Hai Gas Field was estimated to be 550,9
Mton CO2.

The Tran Temple
The Tran Temple in Nam Dinh Province is 4km from Nam Dinh City,
90km south of Hanoi. The site of the Tran Temple now had been the
site of Trung Quang Palace and a temple dedicated to the Tran Royal
Family. The original complex of the Tran Temple was destroyed in
the 15th century by the Ming Troops. The Tran Temple now was
built in late 17th century including three temples: Thien Truong
Temple, Co Trach Temple and Trung Hoa Temple.
Gate to the Tran Temple
Thien Truong Temple is composed of four compartments: Tien
Duong for worshiping ceremonies; Trung Duong dedicated to the 14
kings of the Tran Dynasty, Chinh Tam dedicated to the four
forefathers of the Tran Family, Thieu Huong (Kinh Dan) dedicated to
the mandarins under the Tran Dynasty. Wives of the Tran Kings are
worshiped in the buildings on the two sides of the main one.
The front yard of the Thien Truong Temple, Tran Temple
Co Trach Temple (meaning the old house) was believed the site of
General Tran Hung Dao's home. Co Trach includes 4 compartments:
Tien Duong dedicated to the three generals of Tran Hung Dao (Pham
Ngo, Pham Ngu Lao, Nguyen Che Nghia); Trung Duong dedicated to
Tran Hung Dao and his four sons; Chinh Tam dedicated to Tran
Hung Dao's parents and his family; Thieu Huong (Kinh Dan) home to
a statue of Tran Hung Dao and 9 Buddhist statues. The side
buildings are home to altars dedicated to the generals under Tran
Hung Dao's command.
Thien Truong Temple
Trung Hoa Temple was built on the same site of the Trung Hoa
Palace earlier. At the palace the Tran Kings would return to his home
village (from Thang Long – Hanoi now) to seek advice from the
King's Fathers.
The Tran Temple is a sacred temple which attracts lots of
Vietnamese pilgrims, especially during the festivals' time (13th 15th of the 1st lunar month).
The Co Trach (Former House) Temple, Tran Temple
Paradissa hosts a number of volunteer trips, adventure tours and
relaxing holidays that include a visit to the Tran Temple as well as
other tourist attractions in Nam Dinh Province.
Thien Truong Temple
One of such traditional major festivals in Nam Dinh on February is Tran
Temple Festival.The festival was organized on the 14th night and 15th
day of the first lunar month.
The unique cultural activities, especially the splendid and radiant atmosphere
of “Dong A”, make Tran Temple Festival attractive totravellers everywhere.
Tran Temple in Nam Dinh is a famous destination, where kings of the Tran
Dynasty and their mandarins are worshiped. The structure of this place has
three main buildings, comprised of the Thien Truong Temple (Up Temple),
Trung Hoa Temple (Center Temple), and Co Trach Temple (Down Temple).
Thien Truong Temple was established from the base of Trung Quang Palace
in which the former King lived and worked.
The first aisle of the temple has the altars and plaques of the Tran Dynasty’s
mandarins. The other two aisles in the back are devoted to worshipping the
Tran Kings and their ancestors, and the altars of their queens are located at
the sides of the interior. Co Trach Temple is devoted to Tran Quoc Tuan, one
of the most famous generals in the history of Vietnam, who had three epic
victories for the Tran Dynasty against Mongol invaders.
His family and most reliable assistant are memorialized, along with many other
mandarins such as Truong Han Sieu and Pham Thien Nhan. Trung Hoa
Temple is a new building built in 2000 by the local authorities. This temple is
used to worship all fourteen Kings of the Tran Dynasty along with their most
respected mandarins.
The expression lingered in the mind of the Viet people like a reminder of
finding way back to the root as August and March came to join vivid festivals in
memory of Father and Holy Mother, who founded and protected the
supernatural land.
