TRANSCRIPT
Casing & Connection EvaluationBackground• More than 25 years experience with extreme service applications• Analysis and testing including material behaviour and
full–scale qualification• Testing according to international and company–specific standards• ISO 13679 CAL IV• ISO/PAS12835• Global clients• Reliability engineering basis
Technology Status• URAP® imaging of contact stresses in seals• Advanced FEA for connections and pipe body
– seals, threads, bending, buckling, collapse, creep, high temperature• Thread compound evaluations• Full–scale testing
– connection qualification programs– temperature, internal/external pressure, axial and bending loads – sour environments
• Make–up control software• Completion tool evaluations
– packers, bore seals, bridge plugs• Casing deformation analysis from caliper surveys (CALTRAN)
ISO/PAS12835 thermal connection test string assembly
