GuideWave^® CLEAR Multilayer Mapping-While-Drilling Service

Enables Geosteering in Complex, Extreme-Temperature, Extended-Reach Well

Design and implement a water-injection well to support oil production on the flank of the field.
Position certain portions of the lateral within specific targets. The reservoir consists of two relatively thin porosity layers within a thick carbonate complex. The operator wanted to open the upper zone first, move to the lower zone, and then back to the upper zone.

In collaboration with the operator, Weatherford experts conducted pre-job modeling from the geological and technology perspective to determine the optimal course of action in the extreme temperature range and long horizontal drain.
The teams created the final “drilling on paper” plan—including tools, measurements, and the structural setup—to bring all involved parties together.
To minimize the risk of stuck tools and the loss of radioactive sources, Weatherford engineers recommended a bottomhole assembly (BHA) comprising a rotary-steerable system (RSS) and both the GuideWave azimuthal resistivity and CrossWave™ azimuthal sonic tools.
The well placement service precisely met the operator’s requirements of positioning certain portions of the lateral within specific targets.
The GuideWave CLEAR multi-layer inversion identified reservoir zones and gave insight into reservoir spatial development.
While drilling, a fault was encountered, moving the trajectory into a dense formation, and the geosteering service managed to bring it back into porosity within strict constrains, balancing the trajectory smoothness and necessary non-reservoir zone exposure.

The use of GuideWave CLEAR multi-layer inversion in conjunction with the real-time correlation of all acquired data provided an unsurpassed level of confidence during the execution of the well.
The service proved its effectiveness of the single-well injection in supporting nearby laterals, including those located up-structure.
Under the Weatherford solution, the operator was able to save the cost of a dedicated high-temperature technology and shallower sections material.
By drilling an extremely long extended-reach well instead of multiple wells, the operator minimized the surface footprint, reducing the overall environmental impact.
