Capability of selective formation intervals treatments

Used for hydraulic fracturing and acid stimulations

The top packer is of cup type, the bottom packer is mechanical

The interval to be treated is isolated from above and below enabling its selective stimulation

Over 10 hydraulic fracturing stages with 1 single trip

Can be used for selective intervals pressure testing

The packer features a casing collar locator for accurate positioning in front of the dedicted frac sleeve

Selective packer installation done within 30 minutes

Robust and proven design

Conveyed by tubing, coiled tubing or downhole tractor

Multiple repositioning of the packer

Description

SDT has SELECTIVE STAGE PACKER TOOL technology available for the use with full bore drift ports in unlimited stage fracking applications. Selective packer stage tool can be used for stimulation of new drilled wells and for secondary stimulation operations in old wells.

Full bore drift ports PBS and SHOT types can be used with selective stage packer tool technology.

Features & Benefits

Best solution for fracking stimulation of thin and tight reservoirs

Unlimited number of stages/ports

Maximum TFA for the port’s holes

Wide pressure setting range for ports activation

No risks of premature port’s activation

Cemented and uncemented port’s designs

Ports with option of closure available

SHOT design provides for guaranteed opening of 100% port holes

Up to 10m stimulation interval can be isolated by selective stage packer tool

Can be set and un-set as many times as needed

Build-in couplings locator to correctly position the tool in required zone (no need for other means of BHA positioning)
