QGEP Announces Excellent Results of Atlanta Well Test
RIO DE JANEIRO, Feb. 5, 2014
RIO DE JANEIRO, Feb. 5, 2014 /PRNewswire/ -- QGEP Participacoes S.A.
(BMF&Bovespa: QGEP3, "Company") today announced the conclusion of the drilling
and testing of the first horizontal well (7-ATL-2HP-RJS) of the Early
Production System (EPS) of the Atlanta Field.
Located in Block BS-4, Atlanta is a post-salt oil field 185 km off the coast
of the city of Rio de Janeiro in the Santos Basin in water depth of
approximately 1,500 meters. The well was drilled to a horizontal section
length of 750m and a diameter of 9.5 inches. It encountered a very high
porosity sand reservoir, with average porosity of 38%. The horizontal part of
the well was then cased with screens and packed with gravel, which will
maximize oil productivity while preventing the movement of reservoir sand into
the borehole and production equipment.
A Drill Stem Test (DST) was then successfully performed with two different
flow periods, the first one more restricted in order to collect bottom hole
samples of oil and gas, and the second flow with less restrictions. The two
flow periods produced flow rates of 1,250 barrels of oil per day (bopd) and
over 5,000 bopd, respectively. These flow rates were subject to considerable
constraints associated with the DST set up and limited capacity of the surface
facilities, such as storage, short term flaring limitations and low capacity
electrical submersible pump (ESP).
Furthermore, the test confirmed a Productivity Index (PI) higher than was
estimated during reservoir simulation studies. These excellent results
obtained with the drilling, completion and DST indicated that production rates
of this well, once brought onstream under normal operation conditions and
equipped with a full capacity ESP, will be closer to the high end of estimated
6,000-12,000 bopd range. The results of the tests also confirmed the expected
characteristics of the reservoir and the oil, with high permeability and 14°
As laid out in the development schedule for Atlanta, the Consortium will
initiate immediately the drilling of the second horizontal well of the EPS.
In the coming days, the Company will launch the bidding process for FPSOs of
different capacities, covering both potential scenarios: continuing with the
EPS or proceeding directly to Full Development. The decision on which FPSO
will be hired will be based on the results of the tender and the impact on the
economics of the project. In both scenarios, first oil at Atlanta is expected
in late 2015 or early 2016.
"Production test results came in at the high end of our expected range,
confirming the potential of the Atlanta Field," said Danilo Oliveira, QGEP's
Production Director. "Our experienced team used cutting edge techniques and
equipment, to carry out a highly successful test, demonstrating the technical
know-how that we have built within QGEP. We will continue to apply this
know-how as we develop the Field."
Queiroz Galvao Exploracao e Producao S.A. is the operator of the Block with a
30% ownership; other consortium members include OGX Petroleo e Gas S.A. (40%)
and Barra Energia do Brasil Petroleo e Gas Ltda. (30%).
