Welltec® Magma Packer
High temperature all metal expandable packer for Geothermal Applications
Geothermal energy offers the highest capacity factor in the renewable market and requires a consistently high temperature fluid flow to ensure a reliable output. Welltec® offers multiple solutions using an all metal expandable packer to assist operators in various stages of drilling and completion.
Welltec® Magma Packer can be incorporated into existing casing program helping achieve challenging high temperature cement jobs during new well construction, enable the sustainable rejuvenation of existing shut in wells via re-lining and provide open hole isolation for Enhanced Geothermal Systems (EGS) and stimulations.
Current designs of the WMP are qualified for 260 > 300°C, which can be used for injection and production wells with the possibility of modifications to address specific requirements.
Our ISO 14310 rated, all metal expandable WMP (Welltec Magma Packer) is expanded between the base pipe and the casing or the borehole by applying pressure in the casing. It conforms to the actual well bore geometry or casing internal diameter, providing metal to metal or metal to rock contact, and high strength anchoring capability.
Once the WMP is set, casing Integrity is re-instated via internal hydraulic isolation mechanism.
The packer can be mounted and welded onto any base casing in a simple and cost-effective way. Both ends are therefore fixed and provide life of well protection to the expanded sleeve.
