is designed for side-wall coring in open oil and gas wells to define the lithology, the stratigraphy as well as the rock reservoir properties and their oil and gas water contents.
Features and Advantages
- improved exploration results owing to partial or complete replacement of core recovery while core drilling;
- accurate depth control of the core samples and purposeful core recovery from a desired borehole section specified by well logging data;
- high selectivity, operating efficiency and reliability.
Core sample can be used with a three-core cable up to 4200 m or seven-core cable up to 5500 m.
The set consists of a downhole tool, control console, transformer, communication cable, spare parts, tools and accessories, technical manual and instruction for use.
