Measurement While Drilling
Stay on Target and in Zone with Aim MWD Services
The most crucial tasks during drilling are keeping within lease lines and hitting the target
zone. This involves utilizing directional and logging sensors to ensure the drill string is at
the proper depth, angle, and formation. Operators rely on precise, proven technology in
order to eliminate costly mistakes or trips out of the hole.
Aim Directional Services’ Measurement While Drilling (MWD) technology allows operators
to stay on target and land in zone without worry. Using industry‐proven, robust, highly
accurate sensors; Aim supplies directional and gamma ray logging for any application.
This information is sent up in real‐time utilizing efficient and reliable mud pulse and
electromagnetic (EM) telemetry options to fit any drilling need. Obtain necessary data
on‐the‐fly without costly maintenance trips with Aim Directional Services’ MWD.
Defining Features:
• Proven technology with Tensor based design
• EM will operate in any drilling fluid (mud, oil, air, foam, etc)
• Extreme reliability even in high LCM situations
• Fully retrievable via wireline
• Low or no survey wait time with EM
Aim Advantages:
• Tolteq manufactured equipment provides a rugged and reliable tool string
• Patented lower poppet housing allows mud pulse technology to work even in
formations where high LCM is needed
• Ultra‐low noise receiver allows for deeper drilling with EM applications
• Accurate gamma logging combined with real‐time operating center (RTOC) capability
allows for on‐the‐fly wellpath changes
Real Benefits:
• Highly reliable, proven technology reduces non‐productive time (NPT)
• Mud properties and LCM content won’t affect mud pulse telemetry
• Avoid costly mistakes in wellpath deviation and missed targets
• Low noise receiver in EM and patented poppet for mud pulse save time by
eliminating the need to trip out due to formation resistivities or LCM content
MWD Services:
• Mud Pulse, EM, Dual Telemtry
• Gamma and Resistivity
• Continuous Inclination and Azimuth
• Rotary Pulser, Aim Patented Lower End
• PWD, Near‐bit Inclination/Gamma
