Dwarf ™ Dissolve Frac Plug (Short Type)
Vigor Dwarf ™ Dissolve Frac Plugs (Short Type) revolutionizes temporary zonal isolation with its advanced high-strength dissolvable alloy construction, engineered to deliver superior pressure integrity throughout fracturing operations. This innovative downhole solution completely dissolves post-operation, eliminating costly drill-out interventions while maintaining exceptional load-bearing capacity across horizontal and vertical well applications.
As a 100% dissolvable completion tool, the Dwarf ™ Dissolve Frac Plugs (Short Type) significantly reduces operational risks and non-productive time by leaving no wellbore obstructions, enabling more efficient multi-stage fracturing operations and improved overall well economics.
Description
China Vigor Drilling Oil Tools And Equipment Co., Ltd. is one of the most professional manufacturers and suppliers of dwarf ™ dissolve frac plug (short type) in China, featured by competitive price and fast delivery. Welcome to buy high quality dwarf ™ dissolve frac plug (short type) in stock here from our factory.
Vigor Dwarf ™ Dissolve Frac Plugs (Short Type) are used for multi-layer fracturing operations in vertical and horizontal wells. Soluble magnesium alloys and rubber materials are used to achieve complete degradation of frac plugs.
During operation, the Dwarf ™ Dissolvable Frac Plug is connected to the sealing tool through an adapter. The Dwarf ™ Dissolvable Frac Plug is sent to the designed sealing position by cable or oil pipe. After the position is determined, the tool is sent in for ignition or the liquid is pumped on the ground. The push tube and the middle pull rod are relatively displaced, thereby sealing the bridge plug and letting it go. Then the ball is thrown, or the ball can be put into the bridge plug in advance for direct fracturing operations.
The slip surface adopts button tooth technology. The short structure design reduces the length of the bridge plug, reduces production costs, and accelerates dissolution efficiency.
Features
- Short, Single-slip Design：With a single- versus dual-slip design, the Dwarf ™ is one of the shortest dissolvable frac plugs on the market.
- No mandrel Required：The plug uses a unique wedge mechanism, eliminating the need for a mandrel and allowing for a smaller element, improving dissolution.
- Increased Rate of Returns：Fundamentally, the Dwarf ™ is purpose-built to get to production faster, resulting in an Increased Rate of Return (IRR).
- Configurable：Unlike other dissolvables, the Dwarf ™ can be specifically configured to reliably dissolve in a range of wellbore conditions, accommodating variables like chloride count and temperature.
- Lower Emissions：Compared to conventional completions, the Dwarf ™ significantly reduces production time, along with the associated carbon footprint.
