  Halliburton Delivers Pioneering Logging Technology for Cobalt’s Recent
  Deepwater Pre-Salt Exploration Wells in West Africa

HOUSTON -- January 14, 2014

Halliburton (NYSE: HAL) today announced it has provided wireline services
technology for two deepwater exploratory wells in Angola’s demanding pre-salt
environment 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 drill-stem test risks.

Combined with the standard suite of petrophysical tools, Halliburton employed
its RDT™ reservoir description tool to collect reservoir formation pressure
and samples over the course of three to four days. The tool collected
reservoir formation pressure gradients, mini-drill stem test with straddle
packers and fluid samples in a single run, saving time by working longer than
conventional tools in this hostile environment.

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 and allowing for more meaningful lab results given
that the larger samples offer a better representation of the formation. This
technology produces samples that are 1.5-inches in diameter and 2.4-inches in
length, while eliminating the microfractures typical in percussion cores and
reducing the potential for uncertainties. Rated to withstand temperatures up
to 400 degrees Fahrenheit, the tool saved considerable time over coring
operations performed by previous service providers in some of the most
challenging formations on earth.

“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. “We are proud to be a part of this exciting and new play in the
pre-salt of Angola and with such an innovative operator as Cobalt.”

James Painter, Cobalt’s executive vice president, Execution and Appraisal,
stated, “Utilizing technology that provides representative and meaningful
information in the pre-salt environment enables Cobalt to assess risk,
mitigate hazards and make safe and timely decisions.”

Along with the other tools, Halliburton used its new Integrated Computational
Element (ICE Core^SM) optical fluid analyzer technology to obtain a better
understanding of the reservoir fluid composition. Using ICE Core tool
technology, the company was able to identify which fluid components were
present in a sample.
