Material Characterization

Noetic Engineering offers tensile, compressive and cyclic material characterization services to support high-temperature casing and completion liner designs for extreme-service tubular applications. Given the sustained high temperatures and severe mechanical loading conditions that can exist in these types of wells, it is hardly surprising that standardized testing methods don’t always provide field-representative indications of material mechanical properties. Noetic aims to assist operators and OCTG providers in characterizing, understanding, and utilizing the near-yield and post-yield aspects of material response that can affect the reliability and longevity of severe-service tubulars.

Noetic enables characterization of material properties at field-representative temperatures and loading rates using efficient high-accuracy tensile testing systems and interpretation bases. At present, our climate-controlled uniaxial testing facility is capable of strain- or load-controlled monotonic and cyclic loading with separate temperature control up to 350°C. We continue to evolve our capabilities to suit the needs of our clients.

Project Examples:

  • Elevated-temperature slow-strain-rate tubular material characterizations to support design and procurement activities for SAGD and CSS thermal production casings and completion liners
  • Low-cycle fatigue testing and associated fatigue life prediction basis development for CSS applications
  • Characterization of the axial loading response of globally-constrained SAGD and CSS casing strings through simultaneous mechanical and thermal loading (“thermo-mechanical loading”)
  • Characterization of cyclic “master” curves and cyclic strain-hardening/softening tendencies in cyclic loading applications
  • Investigation and characterization of path-dependent yield strength reductions resulting from near-yield cycling in HPHT tubulars
  • Development of test and interpretation methods for estimating “static” (i.e., very low loading rate) material properties from constant-strain stress relaxation holds
  • Characterization of variability in near-yield and post-yield mechanical properties within individual pipe joints or mill heats and among mills, manufacturers, and API grades
  • Quality assurance programs for verifying production pipe mechanical properties meet specifications and design requirements
  • Development of an optimized material for thermal slotted liner completions
  • Material characterization for advanced numerical material models
  • Development of a robust compressive testing technique for quantifying circumferential mechanical properties of expandable tubular
