Corrosion and integrity evaluation through downhole inspection will support actions to limit metal loss. Control and inhibition is the objective of downhole well integrity strategy in any mature well inventory - contol and inhibition is costly and must be based on reliable data and models. Scale deposits and tubing deformation can obstruct effective well management. Even right at the beginning of the well construction process, monitoring of the effectiveness of wear control during drilling is often critical to long-term integrity of the well, and the optimisation of productive life.
Managing well integrity to avoid unplanned downtime is rapidly becoming a key activity for production engineers around the world. The downhole component of well integrity inspection and control is no less crucial to maximising production or injection up time. READ has the expertise and equipment to support you.
The PVS Pipe Visualisation Suite is much more than just a software imaging package or a combination of integrity logging tools - it is the key to understanding the physical structure of the well and the mechanisms affecting change in the well. It integrates the MFC multifinger caliper, ETT electromagnetic thickness and PTT ultrasonic thickness data. Used by READ analysts to prepare an in-depth report on well condition, it gives you full access to all logged data in a user-friendly format on your desk top PC.
PVS Pipe Visualisation Suite brings together downhole technology with software analysis techniques in the framework of an in-depth understanding of the requirements and constraints of the well integrity questions you need to answer.
The electro-mechanical multifinger caliper MFC - perhaps the most important downhole integrity measurement device, because the science of the measurement is the simplest, most direct and most accurate. The combination of multiple fingers and repeat data sections makes the multifinger caliper the most trusted of downhole integrity measurement tools.
The ETT electromagnetic thickness tool makes measurements of casing or tubing wall thickness and identifies the extent of internal or external corrosion or metal loss. The electromagnetic measurement is effective in any type of well fluid, through scale and other deposits.
Ultrasonic measurement of wall thickness with the PTT gives a very accurate and highly localised measurement of casing wall thickness. This is important when very exact calculation of burst or collapse rating is critical. The nature of ultrasonic sensors and the simplicity of the physics of measurement makes this a very reliable technique.
Downhole camera images transmitted to surface on standard monoconductor can put you quickly in the picture about downhole integrity. The optical option is sometimes the only way to design a fishing string, or look at a problem in the wellhead.
