Schlumberger introduces fully dissolvable plug-and-perf system

16 February 2015 — Schlumberger announces the release of the Infinity dissolvable plug-and-perf system, which uses fully degradable fracture balls and fully degradable seats instead of plugs to isolate zones during well stimulation. This first full-bore interventionless plug-and-perf system ever marketed eliminates the need for milling operations and leaves nothing behind in the wellbore. As a result, no plug debris is produced to the surface, where it potentially could interfere with surface equipment. The technique eliminates lateral length restrictions, which maximizes reservoir contact and estimated ultimate recovery, and it greatly reduces intervention-related risks and costs.

The Infinity system underwent extensive material science and laboratory validation and has been field-tested in multiple unconventional reservoirs across the United States. Numerous wells were stimulated across five of the major plays in North America without any type of mechanical intervention required. A customer in southern Texas deployed the Infinity system in a seven-well project that began with partial wellbores and, after early successes, moved on to full-wellbore completions. The system was deployed under extreme conditions, with temperatures as high as 320ºF in laterals of as much as 8000 ft. In those wells, more than 135 stages were completed without any stages being skipped or any type of mechanical intervention being required.

ICCNexergy introduces lithium-ion battery for seismic exploration

19 February 2015 — ICCNexergy, Inc., a global leader in the design and manufacture of rechargeable power systems, announces the release of its seismic 12-V, 18-Ah lithium-ion battery-pack solution. The new SS-18 battery is an outdoor product that operates in the extreme environmental conditions of the geophysical-exploration market. It is an ideal battery for powering wireless nodes, particularly as a direct replacement for applications that currently use 12-V sealed lead-acid batteries. The SS-18 has built-in charging electronics with LED charge-level indication and smart-battery functions. It is IP68 rated for limited submersion.
