Expand exploration in Pimienta formation
Operating in the Burgos basin, PEMEX needed to
evaluate the shale gas potential of its reserves
within the Pimienta formation located in
northern Mexico. Since tight cost controls and
operational excellence are critical factors for
profitability, the operator needed to implement
the most effective completion design to confirm
reserves and expand exploration in the basin.
Optimized completion design
Schlumberger was selected to develop the
best strategy for characterizing the Pimienta
formation and to recommend an optimal
completion strategy. The BroadBand Sequence
fracturing service, supported by Mangrove stimulation design, was proposed and implemented for the
horizontal wells drilled in the northern part of the
Pimienta formation. This was the first application
of the BroadBand Sequence service outside
US unconventional plays.
Mangrove stimulation design was used to quantify reservoir
and completion quality along the wellbores,
model fracture complexity in 3D, and estimate
well production rates from the complex fracture
networks. The completion advisor module offered
through the Mangrove design was used to create
the most effective completion design and select
the optimal perforation placement, number
of stimulation intervals, and diversion stages.
During the design phase, Mangrove design was
used for simulation of complex fracture geometry
in the heterogeneous Pimienta formation and to
provide a production forecast.
