Standard Wireline Packer System (“SWPS”)
|
|
|
|
SWPS is fully compatible with industry standard drilling systems • Available in NQ, HQ or PQ sizes
|
|
Operation - as easy as 1-2-3 Step 1 - SWPS is run in after inner barrel withdrawn, locks on to the landing ring Step 2 - SWPS is inflated by water and testing is conducted Step 3 - SWPS is deflated and withdrawn, using a standard overshot, inner barrel replaced and drilling recommences. Note (1) A single system is designed to simply work as part of a coring job, a straddle system works independent of the coring phase. Note (2) If the packer becomes stuck withdrawal is effected by using the emergency deflation system.
