Halliburton provides deepwater presalt logging technology in West Africa

Offshore staff

HOUSTONHalliburton (NYSE: HAL) has provided wireline services technology for two deepwater presalt exploratory wells in Angola for Cobalt International Energy Inc. (NYSE:CIE).

The wireline technology enhances the understanding of the rock and fluid properties of the formation, and enables the company to make informed decisions and minimize drillstem test risks.

Combined with the standard suite of petrophysical tools, Halliburton employed its RDT reservoir description tool to collect formation pressure and samples over the course of three to four days. The tool collected reservoir formation pressure gradients, mini-drillstem tests with straddle packers, and fluid samples in a single run.

In addition, Halliburton’s new HRSCT-B hostile rotary sidewall coring tool was deployed on both rigs, taking samples at three times the volume of conventional core samples for better lab results. This technology produces samples that are 1.5 in. (38 mm) in diameter and 2.4 in. (61 mm) in length, while eliminating the microfractures typical in percussion cores and reducing the potential for uncertainties.

“Halliburton’s latest portfolio of technologies, designed specifically for the challenging and often hostile environment of deepwater exploration, performed exceptionally well and delivered key data for the analysis of these wells,” said Brady Murphy, senior vice president of Halliburton’s Business Development and Marketing.
