Mud Pulse MWDAim Directional Services uses the 'Tensor' based wire-line retrievable, positive pulse MWD tools. These types of tools are widely used in most small and mid-sized MWD companies. This is mainly due to their flexibility and availability.
Aim Directional chose to go with Tolteq as our mud pulse MWD tool manufacturer. Tolteq has proven to be an extremely reliable manufacturer of MWD components. They are both innovative and rugged by design. Tolteq and Aim Directional have worked together over the years to create a suite of MWD tools that are just what we want and need in order for our company to stand out in the industry.
We are continually seeking ways to make improvements on the standard 'Tensor' based tool design. That's why Aim Directional came up with a modified poppet housing for the pulser lower end. This patented (US 8,534,381 B1) 'High-LCM' lower end improves the reliability when pumping LCM for the well. Aim Directional has shown to be a leader in supplying our customers with a dependable and reliable MWD tool.
Electromagnetic "EM" MWDOur "EM" MWD tools are the Sharewell EM tools. The EM tools send out an electromagnetic low-frequency signal that's received through a series of antennas at surface and decoded into the MWD information sent up from the tool. This EM tool has the ability to downlink to it for any changes that need to be made, such as the power level for the signal, frequency of the signal, turning the tool on or off, etc. The EM tool reduces the survey and connection time since you're not waiting on the information to be sent up via mud pulse. The EMMWD tool doesn't have any moving parts to fail. It also works in low or no returns of drilling fluid. This tool is ideal for coal-bed methane wells, shallow horizontal wells, and any well with loss of returns above limestone formations.
The EM-MWD tool does have its limitations thou. The resistivity of most limestone formations (i.e.: Austin Chalk) don't allow the signal to be transmitted through it which makes the EM tool ineffective. However, new improvements are being made to improve the ability of getting the signal through these formations.
Gamma RayAim Directional uses CBG and Titan gamma probes. Both are very reliable gamma probes for "Tensor" style MWD tools. We try to get the gamma as close to the bit as possible for geology. We have the ability to create Memory Logs, not just real-time logs from the signal that's pulsed up from surface. This ensures that the gamma log has the correct values from the formation and is not subject to incorrect values decoded at surface from the pulsed up data. Our software is improved with smoothing and filters to create a gamma log as the geology department prefers it. It also gives us and our customers the ability to log into the surface system and view or create logs and LAS files as needed.
