Multi-point Isochronal Tests in Gas Wells

In high deliverability gas (#LNG) wells help to quantify turbulence factors for rate-dependent skin and tubing performance evaluations. An isochronal #welltest can even illuminate blocked, crimped, or parted tubing issues. In Alberta, #AER regulations stipulate that all gas wells with a transient AOF >300 e3m3/d require an isochronal test. BC-OGC generally defaults to AER rules. Saskatchewan gas wells all require an isochronal test.
