No, Akiet High Strength Composite Tubulars are engineered to the specific loads and requirements of the customer’s application.
No, Akiet High Strength Composite Tubulars are in fact engineered for rugged drilling environments. Due to the stiffness and elastic nature of the epoxy resin, which holds the fiber matting together, fiberglass composite has high strength and flexibility.
Under normal conditions there no apparent effect of degradation from UV light. Akiet High Strength Composite Tubular properties show no discernable degradation even when subjected to prolonged exposure to sunlight. For prolonged storage in sunlight (more than 3 months) tubulars are best protected with a tarp or UV resistant coating.
Yes, although Akiet High Strength Composite Tubulars are designed for downhole applications, their strength and chemical resistance can be attractive in other applications as well.
Akiet High Strength Composite Tubulars are designed for the oil and gas industry. No specific precautions are required, however, it is recommended to avoid sharp point loads when handling the tubulars. Low weight will ease the handling during casing, running and handling on the rig floor. Further details are available in the Akiet product handling and installation manuals.
Akiet High Strength Composite Tubulars are made with thermosetting resin systems that do not become brittle even at low temperatures. An epoxy with high tensile strain at ambient temperature shall better cope with impact in sub-zero temperatures. We can design an epoxy-based system specific for sub-zero environments.
Yes, very suitable due to the limited weight and related friction with the side of the wellbore. Akiet’s HSCT stiffness naturally avoids problems with buckling.
No, Akiet offers composite well design and product engineering services as part of its services within reasonable measures.
Yes, although Akiet products are designed to conform with specific dimensions, other customized diameters are available upon request, with consideration to volume.
Mud cake removal represents a critical issue when cementing casings. The smoothness helps to wipe the mud from the casing and generate a better efficient cement bond to the casing.
Yes, it can be evaluated well. The preferred method for cement evaluation is acoustic pulse echo tools (PET): the acoustic pulse echo tools that digitize reflected wave forms can be used reliably to determine the presence of cement behind the High Strength Composite Tubular. The standard cement bond logs (CBL/VDL) is not the preferred method and cannot be interpreted definitively due to the low sonic transmit time through fiberglass pipe.
Yes, High Strength Composite Tubular shoe can be drilled out. Please contact the Akiet representative for details.
No, steel cutters will wear excessively, therefore diamond cutters are recommended.
Yes, Akiet High Strength Composite Tubulars can be perforated downhole. Perforation in cemented casing is preferred. Please contact the Akiet representative for details.
Yes, a window can be milled through the composite tubular when the right whipstock is installed to perform a milling operation. Please contact the Akiet representative for details.
Yes, one of the key advantages of composite tubulars is that they have a very low friction factor when compared to steel tubulars. This low friction factor is constant throughout the lifetime of the pipe because the material does not corrode..
Yes, Akiet has a comprehensive inspection and quality control program starting from raw material receipt, through to finished product and to final delivery. Regular inspections take place throughout the various stages of the manufacturing process. Each product is manufactured in accordance with customer specifications, including quality assessment (trial and testing program) as agreed with customer for specific application.
Yes, Akiet has handling and installation manuals available that include instructions on handling, delivery, and storage of the composite tubulars. Although Akiet HSCT can withstand the rigours of normal practice.
Yes, Akiet will assist the customer with the installation of composite tubulars as safely and efficiently as possible.
Yes, Akiet provides training on site for the adhesive connection system.
The High Strength Composite Tubulars are connected with quick-drying adhesives. Without risk of over-torqueing, unlike other manufactured pipe that is exposed to the issue with threaded composite couplings.
Yes, Akiet High Strength Composite Tubular connection technology has the ability to interface steel-composite, composite-composite and composite-steel and are connected with a quick-drying adhesive for the specific crossover connection. Crossovers are pre-made up and cannot be made in the field.
The main reason why Akiet HSCT have superior performance, comes from a proprietary rotary casting production technology.
The materials used in Akiet High Strength Composite Tubulars are glass fibers and epoxy resin (a matrix which holds filler (E-glass glass) together when cured). A composite tubular is a laminate made from glassfibers and thermosetting resin. It is commonly known as GRE (Glassfibre Reinforce Epoxy).
The specific weight of the Akiet High Strength Composite is 1.80, compare to 7.85 for steel. Strength to weight ratio is at least 2 times better than steel. Glass material and weight varies with size and application, as does the resin bonding type and properties.
Akiet High Strength Composite Tubulars are quite suited to solve corrosion, resistivity logging and extended reach drilling applications. Akiet HSCT can be used for all downhole applications including: geothermal wells, water injection/disposal, oil & gas productions wells, observation wells, salt solution wells, coal bed methane/coal seam gasification wells.
Akiet follows the specific end user standards as agreed upon with our customers.
Due to its superior resistance against chemical attack, most downhole mediums with temperatures less than 100°C. Chemical applications can be confirmed on a case by case specific basis.
