 In the late 70's and early 80's PEMEX initiated the development and exploitation of the offshore fields
Akal, Nohoch, Ku and Abkatun (shallow waters)
 In 2004, Cantarell one of the biggest field in the world, started its production declining

Cantarell, one of the world largest offshore oil field has provided Mexico with a
significant production base. In 2003, this field reached the highest peak production
around 2.2 MMBD.
As Cantarell entered into a depletion stage, water production has increased 160
MBD.

Treatment of heavy oil on shore is considered in actual PEMEX
strategies in order to accomplish water and salt specifications
Cantarell´s heavy oil, Ku
Maloob Zaap and other
fields production are
transported toward TMDB
to adequate water and
salt contained until
required specifications
(contractual limits).

Comments:
1.
The Norm 1996 establishes that if the concentration of Total Dissolved Solids (TDS) is
greater than the environment selected for discarding, as in the case of marine
environment where average concentration of TDS is around 35,000 mg/L, water disposal
has to be 2 km far away from the coast trough diffusers.
2.
In the case of TMDB, water disposal is carry out 3 km far away from the shore through a
diffuser; because of this TDS value obtained in treated water is not out of standard

Objetives
1. Apply JOGMEC technology in order to adequate in platform Akal-G PEP´s
produced water.

Produced water: Water from three-phase separator

Treated water: Following mexican norms NOM-001-SEMARNAT-1996 and NOM143-SEMARNAT-2003 and International rules for out-shore disposal.
2. Facility to PEP authorities the making decision process focused to eventual
acquisitions in produced water treatmeant technology from JOGMEC, following
the current legislation strictly.

Final remarks
 Produced Water Treatment System of JOMEC/HITACHI could be a
technological option to treat produced water in TMDB and dispose it to the
open sea 3 km far away from the shore trough a diffuser without damage
environmental.
 In order to take a final decision related to the possibility to acquire this
technology under current legislation in PEMEX, PEP and JOGMEC will carry
out a final technological test in TMDB with a pilot plant of 10,000 b/d including
the Magnetite Recycling Unit (MRU).
