Composites 101 For Oil And Gas Industry
Composite materials provide long-term resistance to severe chemical and temperature environments commonly found in energy applications.
Manufacturing composite materials for the oil patch requires an understanding of the unique conditions, design considerations, use of materials, performance, turn-around and delivery requirements for the energy industry. Here are answers to commonly asked questions.
Composites are easily drillable, PDC friendly, non-conductive, non-magnetic and perform in environments up to 450° F and 30,000 PSI. Materials can be matched for specific downhole environments.
The most common types of composites are a result of combining reinforcing fibers with resin. Fibers can be a variety of items such as glass, Kevlar, carbon fiber, quartz, basalt or boron.
GP&C utilizes many different resin systems and cloth/roving combinations to meet each component or assemblies’ mechanical loading and environmental requirements.
Our engineers and technicians work jointly with customers early in the process, to develop prototypes, choose the best composite materials and manufacturing methods for construction, and coordinate and conduct in-house testing, assuring an innovative solution for your needs.
It is advantageous to involve our engineers early in the design phase for their expert guidance in using composite material for mechanical applications. Vital recommendations on the front-end will prevent time-consuming and costly changes at the back-end. They are experienced professionals with downhole tool design and composite materials engineering backgrounds and are an excellent resource on customer projects.
Thermoset plastic is a polymer that irreversibly cures and cannot be reprocessed. A thermoplastic is a polymer that can be re-molded and re-processed.
Typically, precision ground shaped mandrel or diamond tooling is used to machine specific features.
The design will most likely change and is dependent on component geometry and mechanical strength requirements.
Composites pack a powerful one-two punch with their ability to be molded into complex shapes at a relatively low cost. This offers designers, engineers and architects a freedom not typically found with other competing materials. Because composites are a blend of reinforcing fibers, resins and additives, they can be manufactured to meet an array of requirements. Designers are free to create exciting new products and, in many cases, are only limited by their imagination.
Composites do not rust or corrode. Products made from composites provide long-term resistance to severe chemical and temperature environments. Composites are often the material choice for outdoor exposure, chemical handling applications and other severe environments. There are many examples of glass fiber reinforced polymer ductwork being in service in chemical manufacturing plants for more than 25 years, operating in harsh chemical environments 24 hours a day, seven days a week. Composites offer corrosion-resistant solutions for many industries, including air pollution control, chemical processing, desalination, food and beverage, mineral processing and mining, oil and gas, pulp and paper, solid waste landfill and water and wastewater treatment.
Corrosion resistance is determined by the choice of resin and reinforcement used within the composite application. There are various resin systems available which provide long-term resistance to nearly every chemical and temperature environment. The choice of reinforcements is much more limited but crucial for certain chemical environments. Properly designed composites have a long service life and minimum maintenance.
Material strength depends on the manufacturing method, and reinforcement cloth weave/roving size and direction.
GP&C maintains strict confidentiality in all interactions with our customers or would-be customers. No analytical data, reports, opinions, discussions and other information are released to any third party without your permission.
Confidentiality is a very important aspect of our work at GPC, and our excellent reputation in the industry is a result of not only our product knowledge, expertise and service, but also of our high code of ethics.
Yes, confidentiality agreements will be signed upon request to our management.
It depends on the geometry. Typically, it is slightly more expensive, but costs can be controlled by using proper tooling.
The design requirements for drillable composites or logging tools exceed those for most other uses of fiberglass materials. This is due to the conditions these materials will be forced to undergo. These conditions include:
- High pressures
- High temperatures
- Compatible with moisture
- Compatible with drilling fluids
- Compatible with cement
- Compatible with most downhole chemicals
Since 1967, General Plastics & Composites has been providing composite materials to the oil patch. We thoroughly understand the unique conditions, design considerations, use of materials, performance, turn-around and delivery requirements for the energy industry.
