Directional Drilling in Cotulla, Texas
Tools and MWD support for horizontal wells in La Salle, Dimmit, Webb and Frio counties on the western Eagle Ford.
Geo Mag Technologies is a directional drilling service company available to operators drilling around Cotulla, Texas. La Salle County lies in the heart of the western Eagle Ford, on the Interstate 35 corridor between San Antonio and Laredo, and the drilling that runs through Cotulla reaches into Dimmit, Webb, Frio and McMullen counties.
Geo Mag provides the mud motors, MWD tool and complete bottom hole assembly needed to drill the well, and it plans the trajectory beforehand. It mobilizes from Broussard, Louisiana; travel distance is not a limiting factor.

The western Eagle Ford around La Salle County
South and west of Pleasanton the Eagle Ford deepens and the fluid changes: La Salle and Dimmit counties span the condensate and volatile-oil windows, and further toward Webb County the play goes to dry gas. Deeper targets mean higher bottom-hole temperatures and pressures than on the northern edge of the trend, and the laterals are long.
That combination puts more demand on the downhole tools. Pulsers and MWD electronics have to keep working hot, and pressure while drilling becomes a practical tool for managing equivalent circulating density on a long lateral rather than a luxury.

Capabilities matched to deeper, hotter laterals
The Rime slick-hd pulser Geo Mag runs is rated by its manufacturer to 175 C and 20,000 psi, and its rotary shear valve is designed for high-solids and high-LCM environments. The pressure-while-drilling tool in the same string is rated to 175 C and delivers real-time ECD through mud-pulse telemetry.
On the drilling side Geo Mag supplies Bico and Tomahawk mud motors, RSS, Key Drill drilling systems and full BHA packages. Surveys are decoded at the rig by the KeyDrill KDU-Mini and logged in Polaris, with the feed shared to the rig WITS system and the operator WITSML server.

Systems relevant to this region
Rime slick-hd servo pulser
Mud-pulse telemetry in high-solids and high-LCM environments
The pulser is the valve that writes downhole data into the mud column. Lost-circulation material, high solids, heat and pressure are what break pulsers; a valve that keeps clearing itself is what keeps the surveys coming.
PWD, annular pressure-while-drilling
Real-time downhole pressure and ECD
Annular pressure while drilling turns equivalent circulating density from a calculation into a measurement. It shows whether the hole is being cleaned, flags kicks and influxes early, and lets the overbalance be held tight without giving up rate of penetration.
KeyDrill KDU-Mini decoding unit
Mud-pulse decoding at the rig floor
Every survey depends on the surface receiver separating a small pressure pulse from pump noise. Deeper wells and PDC bits distort the signal; the lower the pulse a decoder can resolve, the more of the well it can survey reliably.
