Cement Bond Tool cased hole cementing logging tool The Cement Bond Tool is developed to determine cement bond integrity of well casing.
This is achieved by evaluating effect of casing, cement, and formation on amplitude of the acoustic wave generated by the tool. Higher amplitude of acoustic wave received means poorer bond integrity. There are one transmitter and two receivers (3ft and 5 ft as spacing) design. It can be combined with analog GR and CCL tool for depth correction.
FEATURES
Cementing evaluation Gain is selectable according to condition H2S resistant.

Cesium iodide crystals can be divided into three types based on the dopant, CsI(Tl), CsI(Na) and pure CsI. All of them are colorless transparent cubic crystals. CsI(Tl) is the most typical alkali halide scintillation crystal apart from NaI(Tl).
The Production Gamma Ray (PGR) tool measures the naturally occurring radiation that is emitted by various formations to determine lithology. Radioactive scale can also be detected. All models are compact, rugged and combine excellent sensitivity with high resolution for cased hole production logging applications.
