magnetic resonance, VSPs, and mechanical sidewall coring, as well as formation
testing services for pressure and fluid sampling.
The ability to employ a number of
real-time optimization processes during
project execution-supported by a dedicated monitoring center-gave the team
the agility for critical decisions during
drilling based on the best possible information. It also provided the basis for informed decisions that fine-tuned the
more comprehensive wireline evaluation
if a particular zone warranted further attention.

VÍCTOR GERARDO VALLEJO ARRIETA is the leader of the well engineer-

ing multidisciplinary group in Pemex. He
is responsible for the overall design and
well intervention of the exploration
wells that are drilled offshore (deep, ultradeep and shallow waters) and onshore
wells in Mexico's oil and gas basins. Under his leadership, Pemex has designed,
engineered and provided real-time surveillance on 34 of Mexico's 37 deep- and
ultradeepwater wells. Vallejo holds a
bachelor's and a master's in petroleum
engineering from the Universidad Nacional Autónoma de México, and a doctorate in petroleum engineering from
Louisiana State University.

ACIEL OLIVARES TORRALBA is
part of Pemex's group of deepwater
drilling specialists. He joined Pemex in
1987 as an operations engineer assigned to marine assets, and was the
leader of well completion and workover
operations. He is the 2012 recipient of
the Mexican Petroleum Engineering Association's Juan Hefferan Prize. Before
starting his career as a reservoir specialist in geothermal engineering for the
Electricity Commission of Mexico, he received a bachelor's in petroleum engineering from Universidad Nacional
Autónoma de México. He also holds a
diploma in project management and a
master's in business administration.

co-developed with its service providers.
These key insights from current and future
projects will reduce nonproductive time
and improve the formation evaluation
and drilling performance in many well
types and conditions.
