At ISTA group, we provide comprehensive, fully integrated maintenance, overhaul, and refurbishment services for both surface and downhole well logging equipment. With a team of highly skilled engineers and certified technicians, our goal is to ensure that every tool, module, and system operates reliably, accurately, and in full compliance with industry and safety standards.

Our maintenance process begins with a detailed technical inspection, including mechanical, electrical, and electronic evaluation of all components. Using advanced diagnostic systems and precision testing equipment, we identify performance issues, hidden defects, calibration drift, and component degradation. This allows us to restore each unit to optimal working condition through a combination of repair, replacement, and professional refurbishment.

ISTA group performs complete overhauls for a wide range of wireline and logging tools, including CCLs, GR/CCL combos, telemetry modules, power sections, tension systems, depth systems, and acquisition units. All maintenance procedures follow structured workflows, technical documentation, and international guidelines to ensure consistent quality across all serviced equipment.

As part of our commitment to reliability, we use certified spare parts, industry-approved materials, and specialized machining processes for restoring mechanical integrity. We also perform full calibration, functional testing, pressure testing, and environmental simulation to ensure readiness for field deployment under harsh conditions.

Every serviced tool undergoes a final quality assurance stage—including documentation, maintenance reports, test charts, and performance validation—before delivery to the client. Our objective is not only to repair equipment but to extend tool life, improve operational reliability, reduce downtime, and optimize the overall performance of the logging system.

By combining deep technical expertise, advanced tools, and global best practices, ISTA group ensures that your well logging equipment remains safe, precise, and fully operational for sustained field use.
