The process is less equipment intensive than resin injection, although it requires greater expertise for well site evaluation and successful encapsulation. Therefore there should be no expensive long term equipment costs.
Better health and safety aspects. The process uses no solvents compared with resin method and there is little chance of spillage as the chemicals are sealed in pressurised ozone friendly canisters.
Experience has proven that in many areas where no annulus was evident for resin flow, large sections of core integrity were maintained using the foam injection method.
The non-invasive properties allow petrophysics to be undertaken with greater confidence.
The core does not have to be slabbed as in the resin method, for inspection.
The foam does not register on CT scans and subsequently improves data analysis. Core can
successfully be Lithotarge foam injected in large thirty foot sections.
Geological and laboratory analysis work can begin immediately, core can be correctly orientated for analysis and sampling as the foam is easily peeled from the core surface exposing any bedding planes.
Photography in white and ultra violet light can be undertaken immediately on the uncut core through a window cut in the fibre glass or aluminium liner.
Slabbing orientation can be correctly determined to ensure maximum dip showing if necessary.
Full diameter core analysis is available where practical.
The foam has a cushioning protective effect on the core integrity.
The core can be inspected on the wellsite if necessary, core has been sucesfully stabilised using Lithotarge foam injection after a section of the liner was removed along the full core length. This is the only method appropriate to stabilisation of core in half moon liners.
