Cast Iron Bridge Plug (HPHT Type)

Vigor Cast Iron Bridge Plug (HPHT Type) is a robust, drillable downhole tool made of cast iron, used in oil & gas wells for isolating zones, often in high-pressure (HP) and high-temperature (HT) environments (HPHT), offering temporary or permanent wellbore sealing for operations like abandonment, testing, or stimulation, featuring slips and packing for secure setting and easy milling out with drill bits.

Description

Vigor Cast Iron Bridge Plug (HPHT Type) is a highly reliable, permanent drillable bridge plug widely used for temporary or permanent interlayer isolation during stimulation treatments or cementing operations. It can be securely set in casings rated up to V155 steel grade and is easily drilled out. The ratchet-lock ring design ensures consistent setting pressure. The three piece packing element and matel back up rings combine for a superior seal. The case-hardened one-piece slips virtually eliminate premature setting.

Features

● This tool is designed to work with Baker-type wireline or hydraulic setting tool for temporary or permanent sealing of casing, water zones, or low-productivity formations.

● When paired with a hydraulic packer, it is particularly well-suited for challenging well conditions such as highly deviated wells or horizontal wells.

● The plug can be drilled out to restore the integrity of the wellbore.

APPLICATIONS

Application and Benefits

Vigor Cast Iron Bridge Plug (HPHT Type) is designed to work with Baker-type wireline or hydraulic setting tool for temporary or permanent sealing of casing, water zones, or low-productivity formations.
When paired with a hydraulic packer, it is particularly well-suited for challenging well conditions such as highly deviated wells or horizontal wells. The plug can be drilled out to restore the integrity of the wellbore.

What does HPHT mean?

The term HPHT is typically used to describe high-temperature, high-pressure wells that are at either a higher temperature or pressure than most other oil wells – usually over 150°C and 15,000psi at their deepest point. If a well exhibits these characteristics, it is likely to pose greater challenges when drilling. Boreholes with temperatures between 150°C and 200°C are described as Extreme HT, and those with pressures between 15,000 and 20,000 as Extreme HP. Anything beyond this is described as being Ultra-HPHT.

High-pressure, high-temperature drilling should be conducted with synthetic- or oil-based fluids to avoid the risk of a reaction with water-based fluids and the volatile solids in HPHT wells. There is also a risk that compounds within the earth may react exothermically with water.

Often, wells with extremely high temperatures will not be of a commensurately high pressure, and vice versa.

HPHT Classification system

Over the years and across companies, definitions of HPHT have varied. In 2012, the American Petroleum Institute (API) attempted to harmonize accepted terminology and classifications by publishing guidelines for equipment used in HPHT operations. The API Technical Report 1PER15K-1 Protocol for Verification and Validation of High-Pressure High-Temperature Equipment defines a high-pressure well as having pressure greater than 15,000 psi [103 MPa]; a well that has temperatures above 350Â°F [177°C] is considered high temperature. The API operating standards relate to design specifications for equipment, acceptable materials to be used in HPHT operations and the testing of well control and completion hardware to ensure safety, suitability and integrity. According to the API publication, three additional criteria qualify a well for HPHT classification:

Anticipated surface conditions that dictate completion and well control equipment rated above 15,000 psi [103 MPa].
Anticipated shut-in surface pressure in excess of 15,000 psi [103 MPa].
Flowing temperature at the surface in excess of 350°F.

Adapting to cope with HPHT conditions

Given the new technologies available to facilitate the exploration of HPHT opportunities, the number of HPHT wells has increased year on year, with many more planned for the near future.

Their extreme conditions massively reduce margins of error, and the potential for disaster has been realised in the past. The necessity for immaculate planning and an extremely experienced management team cannot be stressed enough. Only by ensuring the following needs are satisfied can success in HPHT operations be possible:

Detection of geopressure;
A fully-integrated team of operators, well technologists, and designers;
Adoption of new technologies; and
Proper management of contractors.

HPHT projects are complicated and precise – demand has not waned, but with technology allowing further exploration in extreme and ultra-HPHT boreholes, the true future yield and risk cannot yet be quantified.
