Schlumberger Key Technology Initiatives in 2013

ONSHORE

Following the availability of the WesternGeco UniQ Integrated Point-Receiver Land Seismic System for lease or for sale, a one-year lease agreement is ongoing for the deployment of the UniQ System in Mexico, which is focused on the quality, efficiency, and productivity of onshore seismic acquisition.

PEMEX awarded WesternGeco GeoSolutions a multi-year contract at its processing center in Poza Rica, enabling access to WesternGeco technologies including full waveform inversion, reverse-time migration, seismic-guided drilling, and rock physics-guided migration. These state-of-the-art technologies will support PEMEX with integrated solutions for enhanced imaging, reservoir characterization, and drilling support.

Schlumberger completed the first horizontal well in the Terra field using over 500m of slotted liner in a highly heterogeneous carbonate play for PEMEX. A flow stimulation treatment was performed using SuperX Emulsion (SXE) and Viscoelastic Diverting Stimulation Fluids (VDA), resulting in an initial oil production of approximately 5,000b/d, which was 66% beyond planned.

Schlumberger Integrated Project Management (IPM) and Drilling Group Technologies introduced the Turbodrilling application to PEMEX, in order to be used on rock formations with high-compressibility. By combining Neyrfor Turbodrilling systems with customized Smith Bits’ hybrid and impregnated bits, the well was able to be drilled effectively. The well interval was drilled in less than 211 hours at an average rate of penetration close to 7ft/hr, saving PEMEX approximately 96 drilling hours compared with conventional drilling systems.

OFFSHORE

Well Intervention LIVE digital slickline technology was deployed for PEMEX on a well at the Ku-Maloob-Zaap field. The LIVE technology provided real-time cased-hole services combined with mechanical services capabilities in a single field unit. Only one rig-up was required to condition the well, run pressure and temperature gauges, and deploy a tubing puncher by using a Testing Services eFire electronic firing head system correlated in real time. The efficiency of the LIVE system in a very limited offshore production platform footprint helped PEMEX to increase well production while avoiding the need for a costly workover rig.

Integration of drilling and measurement technologies through Schlumberger’s PetroTechnical Services helped PEMEX drill a highly challenging section in an exploration well in the Chac field. The use of the company’s SonicScope multipole sonic-while-drilling technology and real-time geomechanics enabled accurate prediction of formation pore pressures so that mud weight could be maintained below the forecasted value. This operation marked the first time PEMEX has used logging-while-drilling and sonic-while-drilling technologies for shallowwater exploration wells. As a result, Schlumberger was able to save PEMEX one casing run by drilling 300m deeper than originally planned.

In the Abkatún-Pol-Chuc complex, a well intervention project combined ACTive’s real time in-well profiling performance and Jet Blaster’s jetting scale removal technologies for the first time in the matrix stimulation of a high-temperature well in the Taratunich field. Data interpretation from the ACTive Distributed Temperature Sensing (DTS) measurements enabled PEMEX to optimize the stimulation treatment in a carbonate formation with highly contrasted permeability profiles

Outside of the operational successes, Schlumberger continues to strengthen its relationship with academia through its University Relations programs, with the various research institutions through the firm’s joint R&D collaboration projects, as well as with the communities where the company works through social development and sustainability projects.
