LWD Resistivity System

Introduction
LWD Resistivity System KTK-LWD is a magnetic field theory based, dual-frequency (2MHz and 400KHz) device, which measures the amplitude ratio and phase difference of the coil received in difference formations, and converts to get the resistivity information. This instrument can greatly enhance the detection efficiency and maximize the cost savings through a combination of orientation with geological parameters that takes drilling engineering services to a new level and provides technical support for exploiting complex oil formations.
Features
● Two-frequency design, symmetrical compensation, eliminate system errors and borehole influence.
● Dual spaced design, prevent the influence from tool eccentricity and dielectric effect.
● Provide 8 curves of amplitude and phase resistivity.
● Easily scale, eliminate effect on communication errors.
● Provide real amplitude ratio and phase difference.
● Modular design, fast and easy maintenance.
● Strong expandability, battery or turbine alternator for power supply.
● Compatible with azimuth gamma module.
● M30 and single bus communication modes are user-configurable.
● Operation software visualization and specialization.
Application
● Provide reservoir geological parameters in MWD, improve detection efficiency.
● Get good formation parameters in horizontal drilling.
● Provide reservoir parameter, increased detecting efficiency.
● Enhanced the oil recovery in thin reservoirs.

Since its inception in the early 2000, KTK Energy has evolved as a respected company, offering a diverse range of products and services to its customers in the worldwide. Today it is a leading provider of oilfield products and services, including rental services at Asia.
At KTK Energy, we are proud of our mission of providing high quality products and services to both our customers as well as our principals. As a reliable and efficient supplier, willing to go the extra mile to provide value solutions, we are also a well-respected and trusted partner for our principals based all across the globe.
When we commenced business in 2000, our activities was primarily trading in drilling mud equipment, pipeline and valves. With passage of time, a wider range of products have been manufactured, includes drilling mud equipment like mud system, shale shaker, centrifuge, mud cleaner, mud agitator and centrifugal pump. Instrumentation products like control measurement instruments, measure while drilling (MWD), gyro, directional sensor, EMS and ESS survey instrument, near bit MWD system. And downhole tools like drilling jar, fishing tools, milling tools, drilling pipe and drilling collars. For more than 20 years, we focused on upstream oil & gas.
On the QHSE front, we continue with our serious efforts for robust implementation across our operations. We have achieved a notable milestone when we received quality standards re-certification from ISO 9001:2008 to ISO 9001:2015.
We are grateful for the continued patronage of our valued customers and the trust of our principals and, will continue to always exceed their expectations.
