Solid Straight Blade Stand-off Centralizers
The original "wellbore friendly" RAY OIL TOOL COMPANY Stand-Off straight blade design provides easy wellbore entry, clean fluid passage and maximum standoff between casing and wellbore. The RAY OIL TOOL COMPANY straight blade centralizer has eliminated squeeze jobs on thousands of wells worldwide - a track record second to none.
RAY OIL TOOL COMPANY solid centralizers provide maximum standoff even in horizontal wells plus allows rotation and reciprocation simultaneously. The RAY OIL TOOL COMPANY solid centralizers were the first centralizers to overcome wellbore lateral forces and give proper casing/wellbore standoff in any drilled wellbore.
The solid straight blade design promotes self-cleaning in the wellbore with less fluid restrictions and drag than bow centralizers and allows pipe to rotate and reciprocate freely inside the centralizer.
RAY OIL TOOL COMPANY centralizers are cast of a high grade metallic alloy with one-piece construction. This design features the lowest drag and wear and fluid restrictions and has high impact and shock resistance, high tensile and yield strengths and corrosion resistance.
The high grade metallic alloy centralizer can now be placed across the productive intervals allowing clean perforations without shot distortion. Casing deterioration due to electrolysis between dissimilar metals is non-existent because the metallic alloy is the softer sacrificial metal reducing casing collapse. The centralizers are designed to slip easily on the pipe's pin end. They can run free on the joint or between stop rings, or can be secured to the casing with set screws.
