Supply of a 143 mm OD single packer, all 316 stainless steel , equipped with a 2” center pipe (OD = 60,3 mm), food grade certified rubber, rubber length = 500 mm.
Complete riserless assembly with cable sealing stuffing boxes, inflation adapters and connections for the submersible pumps.

Net of groundwater circulation wells of 50 meter depth, 264 mm ID casing for in-situ soil rehabilitation ( Pharmaceutical company)
Geological formations : sand and clay
Application: pumping with a submersible pump in a zone isolated by a 220 mm OD Geopro single packer. The outer cover of the packer is made of viton and all metal parts are completely stainless steel made.

Rorary drilling in 8 1/2’’ reamed to 12 1⁄4’’ for deep aquifer exploration, 4000 feet deep.
Sedimentary formation with several artesians aquifers.
Application: sampling different aquifers using a ZI type Geopro double
packer(OD = 170 mm) under mud column . Water sampled by reducing the mud column weight
Results : location of a drinkable water aquifer verifi ed at 810 m deep.

150 m of 12 1/4” (311mm) borehole for drinkable water supply
Karstic formation
Pumping water with a submersible pump from a zone isolated by a Geopro
infl atable packer.
Results : Elimination of turbity and drastic reduction of the nitrate percentage making the water drinkable.

12 1/4’’ boreholes in a lithium mine
Selective pumping of water from different boreholes using a double packer
Supply of a complete 170 mm double packer to fi t the submersible pump.

Thermal water production saturated with H2S
Supply and installation of a casing annulus packer, all stainless steel, OD = 210 mm to be mounted on a PVC riser pipe (OD = 165 mm). Rubber length = 1 meter.
The annulus between the PVC pipe and the center pipe of the packer is sealed using injection of epoxy resin.
For this permanent installation, the packer is equipped with a non return valve and it is inflated with water.

water sampling with a MP 1 pump in a 3’’ piezometer.
Supply of a MP 1 pump assemblied to a 56 mm OD single packer .
Thanks to the infl atable packer, the sampling zone is isolated. The time for testing is reduced and the water sample is representative .
This single packer assembly can be easily transformed into a double packer confi guration if a specifi c zone must be tested.

Site reports - Examples of repair and cementation jobs

Thermal well with casing of 9 5/8” corroded to a depth of 350m.
Rehabilitation of the well by relining the old 9 5/8” casing with a new stainless steel casing of 7 5/8 ‘’ (193,7 X 181mm) and cemented full length to surface.
Method: achievement of the suspended cementation with casing annulus packer of 203 mm OD, cementation valve and infl ation/cementation tool (photo)
Supply of the casing annulus packer, the cementation valve, the tool for infl ation/cementation and technical assistance. Installation of the tool and cementation successfully achieved in less than two hours.

Old water supply well, 260 meters depth; 9 5/8” casing up to 203 meters and open hole down to 260 meters; screen and 9 5/8 casing very damaged by corrosion.
Rehabilitation of the well by relining the old 9 5/8” casing with a new stainless steel casing sealed at the bottom (206mm diameter) and cemented full length to surface (200 mm diameter). Installation of a new screen.
Achievement with the “Swage Packer” method of the setting of the 206mm diameter stainless steel casing between 188 meters and 202 meters.
Supply of cementation valves and installation of a double packer for the cementation job.

Old water well for industrial use (cement factory), 9 5/8” (245mm) casing very corroded up to 160 meters depth; 400 mm open hole below the casing.
Rehabilitation of the well with a new stainless steel 6 5/8” liner combined with a cementation system.
Supply of a casing annulus packer with high expansion capability (400 mm) with a cementing valve. Supply also included a double infl atable packer for cement injection.

Repair campaign on two old water wells, 13 3/8” casing, 57 meters and 72 meters deep both equipped with electric submersible pumps.
Rehabilitation of the complete well by relining the old casing with the “Swage Packer” repair method.
Swaging of a new stainless steel 10” casing. The 315 mm ID diameter after completion of the swaging operation allows reinstallation of the same 10” pump.
