Drill inspection is executed as per customer-nominated standards, using case-appropriate techniques. Electromagnetic Inspection (EMI) units are utilized at intervals guided by drilling conditions and past failure experiences. A.C. Yoke Magnetic Flow technique is used for most inspections, while sandblasting units are employed to prepare inspection surfaces.
Bottom Hole Assembly
A well-maintained bottom-hole assembly supports a high drilling performance. PTIS conducts BHA inspections as per API RP7, DS1, NS2, or other standards as nominated by the commissioning clients.
Tubing / Casing
From a visual inspection of the body (and thread) to identify external damage, to full-length drifting of the tubular structures, all are performed by PTIS. Additionally, maintenance services, namely cleaning, coating, hardness-testing, thread-gauging, and ultrasonic wall-thickness measurement are conducted by PTIS technicians.
PTIS provides technological support for directional drilling, casing drilling, and bore-hole enlargement. These are capably combined with the flexibility of seismic-guided drilling services to deliver efficiencies in the areas of utility-construction and slant drilling.
