Any failure of a well completion string or tubing - the result of corrosion problems, scale build-up, crushed or damaged well completion items - has long been recognized as a major source of production problems, one that may irrevocably lead to well abandonment. Well-recorded data of downhole tubular conditions is needed to maintain field recovery through remedial work, in order to maximize production.There are many types of measurement service available to monitor the down-hole tubular condition, the “Multi-finger Imaging Tool is one whose data can be processed with 3D Visualization software, to be of further use in detailed interpretation.The Multi-finger Imaging Tool provides high resolution data sets, measuring miniscule changes in tubular diameter. These data are then processed with 3D Visualization software to provide an excellent overview of actual tubular conditions from any angle, position, depth, or display cross-section.This poster presents a case study of the MIT performing an inspection for a TRSV Damaged Sealbore in a TEPI well. By comparing the 3D Visualization results with an actual well completion diagram and mechanical dimensions of the Tubing Retrievable Straddle Packer (TRSV) safety valve, our group managed to find a solution to this problem.As a result, the well was put back into production in December 2007.
