Majorpack is an emerging leader in industry standards and technology for OCTG anti corrosion coatings. Years of extensive research and product development have concluded that multifaceted systems are necessary for complete corrosion protection of downhole tubulars. Our experts have tested and created exclusive coatings to ensure protection from all corrosive agents in any given environment including, but not limited to: H2S, CO2, and bacteria. Our success is proven through numerous field studies in some parts of Europe, Russia, Kazakhstan.
Types of MP coatings
- MPAG17 – latest dyplex system from paraffin deposits and 100% of tubings surface is being protected along with thread connections
- MPLAG17 – this coating was developed as a special protection from paraffin deposits
- MPLAG96 – to protect the inner surface of tubulars in high CO2 environments
- MPAG96 – dyplex system for H2S corrosive environments including bacteria
- DELTA5+ – dyplex system was mostly designed for sucker rod pump
One of the most widely spread complications in the oil and gas industry is the production of high-viscosity fluid, which consequently leads to different deposits on tubing walls. These deposits cause the gradual decline in production volume and extra operational costs. Often the deposit problem on high-viscosity oil wells is not taken seriously, when problems with production arise. MPAG17 has been designed specifically for these complications. It was created to specifically focus on deposit mitigation. This internal coating reduces asphalt-paraffin deposit and can be used with acid treatments to fight the deposition of other solids. Majorpack MPAG17 can be applied to both new and used tubular goods, making it versatile and cost effective.
It is recommended for tubulars with non-upset or upset ends, sucker rods and at the fixture elements (couplings, reducing taper elbows). It is highly recommended to use the Majorpack Protective Streamer (insert) for the protection of the inner surface of a coupling.
Gas corrosion (H2S,CO2)
Our prototype coating, MPAG96, differs from competing products because it has a diffusion intermetallic primer that covers 100% of the tubing surface. Additionally, there is an epoxy-polymeric coating (6-14 mils thick) applied internally.
MPAG96 was specifically designed for equipment operated under highly corrosive environments including bacteria, H2S and CO2. The duplex coating structure uses a combination of protective qualities from several materials that mutually complement each other. Essentially, the well-known weak points of one layer are smoothed over by the strong features of the other.
This coating is designed for corrosive conditions where the operating process is characterized by the harsh (even unfavorable) thermal conditions, corrosion-active gases and fluids. The long and safe performance of this coating very much depends on the service conditions and the specific aggressive environment in oil wells.
MPAG96 includes an inter-metallic primer (chemically more active than iron) which works as a protective layer to the corrosive fluids in an oil well. This layer covers 100% of the tubulars ID, OD, threads and connections. In a third-party U.S. lab test, this intermetallic proved to be impervious to acid producing bacteria (APB) and potentially poisonous to sulfate reducing bacteria (SRB).
MPAG96 has a micro-hardness several times higher than that of Grade E Steel. This provides supreme resistance to mechanical wear. For example, instead of 4-6 round trips, the threaded connection can withstand in upwards of 50 round trips. The top thermoplastic performs additional barrier functions that prevent the access of aggressive mediums and fluids to the body of tubing and the protective layer. This results in complete protection of the system and substantially increases the time between failures.
MPAG96 coating includes all the best features of its predecessors. Additionally, tubing with MPAG96 coating can be used in low-temperature environments with heavy crude oil. It is also successful in environments that struggle with scale deposit formation. Perhaps most notably, the physical properties of MPAG96’s hydrophobic polymer surface make it an excellent candidate for asphalt-paraffin deposit environments. MPAG96 is recommended for tubulars with non-upset or upset ends, sucker rods and at the fixture elements (couplings, reducing taper elbows). It is highly recommended to use the Majorpack Protective Streamer (insert) for the protection of the inner surface of a coupling.
Gas corrosion (H2S,CO2)
MPLAG17 is a polymer coating aimed to prevent paraffin deposits along with different types of corrosion. It is equipped with a liquid base to ensure higher levels of surface adhesion and to withstand harsh environment conditions. MPLAG17 is a coating with a very smooth surface that was specifically designed for paraffin mitigation. MPLAG17 protects the inner surface of tubulars in high level of CO2 environments as well as other corrosive environments.
Tubulars protected with MPLAG17 can be repaired without complications after being placed in operation, reducing downtime and increasing productivity. MPLAG17 is actively used in different oil field environments and substantially increases time between failures.
Gas corrosion (CO2)
MPLAG96 is a polymer coating aimed to prevent different types of corrosion. It is unique because of the innovative liquid base. This liquid base achieves very high levels of adhesion (>10MPa) to the inner surface of tubulars and results in a coating that can withstand very harsh environments.
This type of coating was designed to protect the inner surface of tubulars in high CO2 environments, as well environments that are complicated by salt and oxygen. One major benefit to MPLAG96 is the ability to be repaired without complications after being placed in operation. This results in less downtime for failures and higher production for consumers. Majorpack MPLAG96 is widely used in varying oilfield environments and substantially increases the time between failures. MPLAG96 has been approved by several leading oil companies.
Gas corrosion (CO2)
Duplex (Intermetallic + Epoxy-polymeric) protection system, providing high corrosion resistance and due to its microhardness and reliability can operate in the most aggressive environments of oil and gas production, including oil wells, complicated with CO2 and H2S corrosion, high temperature, and abrasive wear. Delta5+ coating combine barrier and sacrificial corrosion protection so that even the formation of sites of damage or partial absence of coating does not lead to the development of corrosion. In addition the special properties of the basic intermetallic layer lead to high reliability of pipe’s thread connection and give tenfold increase in the number of cycles of make and breaks.
Gas corrosion (H2S,CO2)
The Majorpack Protective Streamer or MP Streamer is an insert made for the protection of the J space in oilfield tubular connections. It is designed to prevent corrosion of a threaded connection. Often the threaded connection is damaged by turbulence in the unprotected part of the connection. The MP Streamer resolves this issue by minimizing and eliminating the space between the tubing and coupling connection. The MP Streamer secures the joint, preventing it from abrasive and erosive wear.
- registered (patented) construction
- adapted for the triangular thread, prevailing in the Russian oil production industry
- protects the tubing’s nipple from the production fluid
- protects the vulnerable inner surface of a coupling from washing out corrosion caused by the production fluid
- MP Streamer’s width is adapted for the exact joint «tubing-coupling»
- operation temperature: 392°-420°C
- MP Streamer is easily installed without special training and installation can be done in field conditions at the pipe yard without using some special facilities.
- MP Streamer can be used regardless of tubing’s condition – in new and used ones.
- Minimizing and eliminating the gap connections “tubing-coupling” MP Streamer provides tightness of connection, thereby preventing abrasive and erosive wear due to the high speed exposure of the production fluid (flow)
