The patent introduces a revolutionary Cylinder-less High-Pressure High-Temperature (CLS HPHT) Liner Hanger, addressing challenges in deep oil and gas well completions. The CLS LH utilizes a single-body Mandrel with Pistons and a spring-based mechanism, eliminating traditional cylinder activation. This design enhances performance by avoiding burst and collapse issues seen in standard Liner Hangers. The Mandrel's streamlined structure, made from corrosion-resistant alloy or steel alloy using additive manufacturing, improves overall efficiency. Dynamic sealing systems and Compression Springs contribute to high-temperature capabilities. Activation occurs without the need for internal liner pressure, setting it apart from conventional counterparts. The CLS HPHT Liner Hanger, detailed in this patent, represents a significant leap in wellbore integrity, offering a robust and efficient solution for extreme downhole environments in oil and gas well completions.
A Cylinder-less High-Pressure High-Temperature (CLS HPHT) Liner Hanger for oil and gas well completions, comprising a single-body Mandrel with strategically positioned holes and grooves, said Mandrel designed to eliminate the need for a conventional cylinder-type activation mechanism, wherein individual Pistons housed within the Mandrel are activated by Rupture Discs, initiating a sequence that releases a Collet, enabling Slips to anchor the Liner Hanger radially with the casing, and further wherein the CLS LH remains in its initial position during the running process without requiring pressure from inside the liner for activation.
A Cylinder-less High-Pressure High-Temperature (CLS HPHT) Liner Hanger for oil and gas well completions, comprising a Compression Spring strategically positioned between a Collet and Shifting Sleeve, said Compression Spring playing a pivotal role in the activation process, ensuring consistent force application, and reliable anchoring of the assembly with the casing.
A Cylinder-less High-Pressure High-Temperature (CLS HPHT) Liner Hanger for oil and gas well completions, comprising a corrosion-resistant alloy or steel alloy Mandrel manufactured using additive processes, said Mandrel featuring a streamlined design with strategically positioned holes and grooves, eliminating the need for multiple parts and significantly improving overall performance.
