Halliburton has introduced StrataStar™, a deep azimuthal resistivity service that provides multilayer visualisation to maximize well contact with the reservoir and improve real-time reserves evaluation.
Unveiled on Tuesday, Haliburton explained that regardless of the complexity of a reservoir, wells accurately placed in the most productive zones help operators maximise asset value and this is where the StrataStar™ comes in.
The American multinational’s deep “azimuthal resistivity service” from Halliburton Drilling delivers advanced measurements and processing to improve real-time reserves evaluation while optimising borehole placement to increase well production.
Encompassing the robust, compact design of the iStar™ intelligent drilling and logging platform, the StrataStar service embodies innovation by combining a novel antenna, mounted on a modular tool, with a suite of advanced inversion techniques. And this service provides better data interpretation, widens the volume investigated, and increases the amount of information collected in real time to precisely steer wells where they will most benefit operators.
The StrataStar service makes deep azimuthal measurements up to 30-feet around the wellbore; a sophisticated processing algorithm inverts the data and maps the positions, thicknesses, and resistivities of interbedded rock and fluid layers.

The company said realtime visualisation of the surrounding geology and fluids provide key information required to precisely place the well and maximise reservoir contact.
The StrataStar service also provides shallower multi-frequency measurements over four spacings to deliver a comprehensive understanding of resistivity across the widest range of fluids and rocks.
“The innovative design of the proprietary crossed transmitter antenna enables the computation of anisotropy in real time, enhancing formation characterisation.
“Real-time access to Rv and Rh in a relatively undisturbed environment drives a more accurate calculation of the water saturation, further supporting advanced petrophysical analysis of the reservoir,” the company explained.
With Halliburton as a prime contractor of ExxonMobil in Guyana, the country stands to benefit from newer technologies adopted by the company.
In a January analysis, Norway-based consultancy group Rystad Energy had said that some of the wells being spudded in Guyana are at the ‘bleeding edge of technology’ and represent drill campaigns that have never been done before.
