Saltel Steel ECP-C
External Casing Packer
ECP stands for External Casing Packer. The Xpandable Steel external casing packer is based on proprietary expandable stainless steel technology.
Key Features of the External Casing Packer
The external casing packer (ECP) is a well-known tool in the oil and gas industry that provides excellent zonal isolation during cementing operations. ECP stands for “external” because it is installed on the outside of the casing, which enables easy removal and replacement if required.
Benefits of Using the External Casing Packer
One of the main benefits of the ECP is its expandable sleeve, which deforms and sets between the casing and borehole by applying pressure in the casing. The sleeve conforms to the real wellbore shape, sealing with the borehole’s uneven surface, thanks to the patented thin layer of bonded elastomer. The sealing element comes in lengths of 4ft or 8ft.
Furthermore, ECP stands for a “one-piece mandrel” design that eliminates the need for welding or machining operations on the base casing, saving time and money. The mandrel also provides high sealing and anchoring of the packer ends with the base pipe.
Another important feature of the ECP is its expansion valve. It closes permanently after the ECP installation and activates when it reaches a pre-determined pressure level. The extremity design protects the valve system during the running in hole (RIH). Besides, the valve systems comes with a safety device in case the ECP expands in front of a wash-out.
ECP stands for Versatility in Various Wellbore Conditions
Moreover, the ECP is a versatile tool. This packer is indeed workable in doglegs or tight spots, preserving casing integrity after the setting. It can also seal effectively in oval, out-of-gauge, or irregular boreholes, making it an ideal choice for various wellbore conditions. With its quick installation time and expansion on demand, the ECP is a popular choice in the industry.
To sum up, the ECP stands for an external casing packer that offers excellent zonal isolation. The packer is mounted on the outside of the casing. Its expandable sleeve comes as a one-piece mandrel, and the expansion valve is part of the key features that make it a popular choice in the industry.
