MEASUREMENT WHILE DRILLING (MWD)

Accurate data while drilling allows you to optimize your wellbore placement to reduce non-productive time and costs. Our team enables you to drill reliably even in high- vibration, high-temperature and other harsh environments. As wells become deeper and more complex, we provide a constant stream of data for precise wellbore placement, reservoir navigation and drilling optimization. ALLTEC uses sets of highly reliable MWD/LWD system, manufactured by APS Technology, The Mud pulse directional (D&I) and gamma systems provides reliable and flexible Measurement While Drilling (MWD) performance in combination with Rotary Pulser – the toughest top- mounted pulser in the industry. This MWD system provides highly accurate azimuth and inclination data for all applications, from straight-hole through horizontal drilling. Rapid and accurate toolface transmission enables the most complex well paths to be drilled with confidence. The mud pulse MWD system's downhole tool includes a rugged directional sensor package with NIST-traceable magnetometer calibration; a reliable, field-proven Rotary Pulser. The APS MWD system uses either battery pack(s) or a turbine alternator, which can be run alone. The APS Turbine Alternator† is a high-temperature, axial flow design for use in measurement- while drilling (MWD) and logging-while-drilling (LWD) systems. This device provides reliable, ongoing power at temperatures of up to 175°C, taking the place of expensive, short-lived disposable batteries. The turbine is configurable to match the required flow rates for typical BHA/hole size combinations

LOGGING WHILE DRILLING (LWD)

APS's WPR sub is a spatially compensated, dual frequency (400 kHz & 2 MHz), dual spacing device designed for wireline-equivalent Logging-While-Drilling (LWD) and Measurements-After-Drilling (MAD) services in all well types. The Resistivity Tool (WPR) is symmetrical design, with centrally located receive antennas, provides real-time compensation, eliminates invasion effects due to measurement delays, and improves accuracy by canceling variations in receiver channels. WPR operates in all mud types including oil-based and salt-saturated and provides real-time resistivity with flexible transmission formats. High-resolution data is stored in downhole memory which can be retrieved and processed during trips. APS provides a complete set of software-enabled borehole corrections and applications with WPR, including a dipping bed model for geosteering .
