Defined as geologically guiding the well path, geosteering guides decisions in real-time or near real-time to provide maximum exposure to production zones. Stratagraph’s experienced geosteering professionals offer expertise on subsurface geology and directing the well path while assisting with streamlining operations and enhancing communications with operations geologists, wellsite supervisors, directional drillers and MWD/LDW hands.

GEOSTEERING SOFTWARE

Remote Geosteering
While not all conventional plays are suited for remote geosteering, eligible sites are offered an alternative route to drilling efficiency that improves safety and reduces overall costs. Remote geosteering involves gamma markers, continuous supervision and consistent communication for optimal landing in the build section for most horizontal wells. Remote geosteering can assess hole conditions by monitoring drilling parameters and mud properties, paying particular attention to any indications of overpressure zones, sticky holes, or lost circulation.

Lowering the risk of accidents through fewer logging hours and fewer people at the wellsite, exposure to hazards at the wellsite is reduced through remote geosteering. With geologists working close to home, transportation costs are minimized, and accommodation costs are eliminated. While working remotely, our geologists are acquiring continuous drilling and MWD parameters to decide the optimal steering direction in Real-Time at any distance. Decision can then be instantly relayed to directional drillers.

Drilling a borehole in complex geology requires continuous adjustment of the borehole trajectory to guide a path to one or more reservoir targets. Achieving the correct adjustments is possible through real-time well trajectory monitoring, where data availability and expert log analysis results in the identification of reservoir boundaries even in dipping and fractured reservoirs. Stratagraph utilizes Stoner Engineering Software (SES) for both horizontal and directional drilling because it allows for the plotting of the actual trajectory of the well while drilling. When combined with other data, such as Total Gas, Gamma Ray, Resistivity, and ROP, SES is a valuable tool in allowing us to remain in the target zone while drilling the horizontal section.

SES also generates a three dimensional model of the well as it id drilled which is useful for additional applications such as completion plans and improving drilling plans for future wells.
