First-of-its Kind Technology Delivers Early, Accurate Volume Measurements in Unconventional Resource
HOUSTON – Aug. 25, 2014 – Halliburton's Wireline & Perforating business line (NYSE: HAL) today
introduced the CoreVault™ system, a unique solution that provides a more accurate volumetric picture of the
amount of oil and gas trapped in unconventional reservoir rocks. The system for the first time allows
operators to contain and bring the reservoir fluids within rock samples to the surface, allowing for
measurement of the volume of hydrocarbons-in-place.
David Topping, vice president of Wireline & Perforating, explained that "prior to the development
of the CoreVault system, when traditional coring tools were used to bring samples to the surface, they
allowed 50 to 70 percent of the hydrocarbons to escape from the rock as the samples depressurized. Building
a model of the volume of oil and gas in a reservoir thus required operators to estimate this fluid loss
rather than measure the fluids in place, and estimates were often inaccurate. By preserving 100 percent of
the fluids within the core sample, the CoreVault system allows for an improved understanding of potential
production within the reservoir."
The CoreVault system builds on the capabilities and reliability of the Halliburton Hostile Rotary Sidewall
Coring (HRSCT-B™) Tool that recovers 1.5-inch-OD cores at temperatures up to 400°F (204°C) and pressures up
to 25,000 psi. The CoreVault system, when combined with the HRSCT-B tool, allows up to 10 cores to be
sealed at reservoir conditions in a single wireline run, saving time over full-hole coring and allowing
more targeted samples to be taken.
Don Westacott, chief advisor, Global Unconventional Reservoirs, said, "The samples taken with the
CoreVault system often reveal dramatically more oil and gas in place than previous estimates would
indicate. The information obtained can significantly enhance economic value and reduce exploration and
development risk for our customers." An operator in Ohio and West Virginia used the system to retrieve
150 samples in five wells, with measurements of the samples showing 2.5 times more oil and gas in place
than had been previously estimated.
