Swell Packer by Easy Well Solutions

Swell Packer enables water control in open hole. Reliable and permanent annular isolation is normally required to enable water control in open hole completed wells. The Swell Packer, supplied by Easy Well Solutions is an annular isolation packer expanding and sealing in contact with hydrocarbons. Installation does not require any operations or manipulation. This saves rig time and increases reliability. The Swell Packer is installed across a formation barrier and left in place. It can be used for open hole and cased hole and is available for non-standard casing sizes.

In a mature North Sea field, North Cormorant, operated by Shell UK a through tubing drilling campaign was ongoing. The operations required zonal isolation from along the reservoir due to multiple intermittent layers with water and oil. Cementing these reservoirs was a challenge because of the small pipe diameters, ambitious drilling targets and high pressure contrasts. The operator performed a detailed analysis and found that Swell Packer would enhance the operations. No problems were associated with the installation. The packers provided better zonal isolation properties than cement. Perforating was avoided. By simplifications of the well design, the system has saved close to 50 percent of the total well cost.

In a shallow, viscous oil development in Alaska, U.S., an operator drilled multilateral wells to drain four zones. The bottom lateral was drilled undulating between two zones with five penetrations of the mudstone separating the zones. Previous wells have been plugged within a month after onset of production. To avoid this mudstone to mobilize and spread to plug adjacent slotted liner, a Swell Packer was positioned just above and just below each of these mudstone intervals. No plugging related production impairment has been seen in these wells.

To date, more than 250 Swell Packers have been installed in a multitude of downhole environments in different areas of the world. The installations has been with water control, open hole fracturing, sand control and many different applications. All installed packers have performed to expectation and no sealing failure has been detected.

Baker Oil Tools' REPacker™
Reduce operational, HSE, and wellbore damage risks; cut overall cost
We offer several types of reactive element packers that are triggered by contact with well fluids. Our packers will cut your overall costs and reduce HSE and wellbore damage risks.
Our Baker Oil Tools' REPacker™ is a self-energizing, reactive-element, swelling-elastomer packer that provides a long-term barrier to annular flow around tubular assemblies in either open or cased-hole. No cement is required. It is ideal for deviated wells.

The highly reliable packer has no moving parts and is available in oil- and water-reactive, non-reversible elements. There is no risk of elastomer shrinkage if fluids are changed after swelling. Deployment and installation are simple and do not require running tools or specialized personnel.
The packer is a sealing device built on a casing pup that matches the mechanical properties of the liner. The activation methods for annular sealing are the swelling properties of the rubber element reacting with wellbore fluids. This packer can be used in openhole or perforated casing to isolate unwanted formation production.

The FORMpac™ expandable packer with reactive element technology eliminates annular flow around liner assemblies. It is a sealing device built on expandable solid pipe technology. The primary activation method for annular sealing is expansion of the solid pipe mandrel. The secondary activation method is the swelling properties of rubber in all hydrocarbons except very lean, single phase gas. This thermodynamic absorption expansion is continuous.

The tool can be used in openhole or perforated casing to isolate unwanted formation or production. The FORMpac packer provides a simple and effective method to eliminate the linear annular flow of fluids in cased and open holes with maximum pass-through ID. It will isolate troublesome shale in openhole completions. The packer can be used with both standard and expanding liners and sand control screens.

Our RCPacker is used in openhole wells to isolate unwanted formation production. When used together with our EQUALIZER™ inflow control device, it can efficiently manage flow in the annulus. The reactive core (RC) packer uses non-cement inflation media for permanent isolation in openhole completions.

A swelling reactive core is protected by an inflatable element. The initial seal provided by the inflatable element is less affected by downhole pressure and temperature changes after the core of the packer system has reacted with its inflation fluid. The element uses our XTremeZone™ technology for enhanced run-in capabilities, along with internal metal reinforcing on either end to provide high differential capability.

The REBarrier uses a self-energizing swelling elastomer to reduce the annular flow of fines and other wellbore debris in open or cased-hole. The packer is a sealing device built on a substrate that can be easily installed on your casing. The activation methods for annular sealing are the swelling properties of the rubber element reacting with the wellbore fluids.
Our REFlex™ field-installable reactive element packer is installed onto nominal API base pipe. The primary purpose of the tool is to add flexibility in deployment and further simplify your completions. The REFlex packer is built with a rigid steel cage that is surrounded by a proprietary Baker Hughes reactive element rubber matrix.
