Pressure measurement at a single point Pressure measurement at multiple points (multiple straddle packer) Packers for grouting, sacrificial/retrievable Wireline packers Grout filled packers Casing sleeve packers Large diameter packers to seal and grout pipes and tunnerls Wireline grouting packers for squeeze cementing Fluid sampling at single or multiple locations Well screen lifting Hydrofracture packers Impression packers Self inflating injection packers Flexible packers for use in confined situations No doubt there are other uses we haven't considered
Describe:
Define Hole Profile -
Maximum un-inflated diameter
Minimum inflated diameter
Minimum inflation pressure capability in unconfined state
Expected maximum diameter at which the packer should seal
Maximum scaling pressure required between the packer and the borehole wall at the maximum sealing diameter
Minimum length of packer in contact with the borehole wall at the maximum sealing diameter
Maximum length of packer assembly un-inflated
Lifting weight if the packer required to lift screen or casing etc
Preferred means of inflation
Media for Inflation
Required life when inflated
Corrosion/deterioration risks
Special valving required - eg for DST tool or non return inflation lines
