Vigor specializes in the production of non-magnetic drill collars, drill pipe, and heavy-weight drill pipe (HWDP) that meet the standards of API Spec.7-1, 5DP, and NS-1. Our non-magnetic materials are equivalent to P530, P550, and P650, ensuring a high level of performance and reliability.
Our non-magnetic drill collars are made from a specially forged low carbon high-chromium manganese alloy steel. We maintain strict control over the chemical composition during the refining process to achieve superior mechanical properties, such as high strength and low magnetic permeability. This material also exhibits excellent resistance to intergranular corrosion cracking and wear.
These non-magnetic drill collars are crucial for directional drilling applications, where precise well trajectory is required. By using instruments inside the drill string, such as magnetic survey instruments (MWD) and logging while drilling (LWD) tools, we enable magnetic surveying of the well trajectory. The MWD instruments are located in the non-magnetic drill collars, allowing precise measurements of the earth's magnetic field without magnetic interference.
Our non-magnetic drill collars provide an effective solution to the issue of magnetic disturbance caused by steel components in the bottom hole assembly (BHA) and drill pipe. By isolating the survey instruments from such disturbances, we ensure accurate and reliable measurements are obtained during drilling operations.
With sizes available from 3 1/8" up to 11", our non-magnetic materials can be used for a wide range of drilling applications. We are committed to delivering products that excel in performance and durability, meeting the highest industry standards. Trust Vigor's non-magnetic drill collars, drill pipe, and HWDP to enhance your drilling operations with improved magnetic surveying capabilities and increased efficiency.
