Primary and secondary wellhead seals are located at the wellhead, which is the structure at the surface of a well that provides access to the subsurface. The primary seal is typically the first line of defense against fluid escape and is directly in contact with the wellbore, while the secondary seal serves as an additional barrier, positioned below or around the primary seal to provide extra protection. These seals are essential for maintaining well integrity and preventing leaks.
They are secondary consumers. It is sure that larger animals will eat them like sharks and seals.

Wellhead Equipment is a very important piece of oilfield equipment. We can classify Wellhead Equipment as conventional components. Wellhead products that consist of base plates which are easily detachable from the casing head for reattaching and welding. Such Equipment provides extra load for supporting the higher case loads. Wellhead casing has a straight bore design that accepts casings of different hangers. The line pipe threaded outlets, studded or flanged outlets can be also provided. Bottom preps include a slip on weld and threaded connections. Casing hangers type of equipment combine pack off and slip bowl hangers. Wellhead is easy to install and is also fluted for allowing the cement returns. Wellhead Equipment can also be included as the casing spools that have a top bowl configuration. Equipment has locking pins. Wellhead secondary seals help in the installation of tubing heads and casing spools to provide pressure energized secondary seals. Wellhead tubing has a fully opened straight bore design with a dual completion head available and is compatible with a variety of tubing hangers.

The primary consumers in the Arctic Ocean are phytoplankton and crustaceans that consume the zooplankton. Harp seals are secondary consumers, which mainly eat fish like Arctic cod and Arctic char, and some crustaceans. The top predators, or tertiary consumers, are polar bears and the Orca whale.
A secondary consumer in a food web is the carnivorous or omnivorous animal that feeds on the primary consumer, which is the organism (normally a plant) that eats the producer (normally a plant).
Secondary consumers eat herbivores, which are primary consumers. An example of this would be a lion that eats a zebra. The zebra is a herbivore and so the lion is a secondary consumer. Almost all carnivores are secondary consumers.
it is a tertiary consumer- producer is the plant/ algae, the primary consumer is the fish, the secondary the crab that eats the fish, the tertiary the seal that eats the crabs.
Sharks are considered primary consumers because they mainly feed on other animals like fish, seals, and squid. They occupy a high trophic level in the food chain as they are apex predators in marine ecosystems, playing a crucial role in regulating populations of prey species.
Secondary and Tertiary Consumers that are in the Neritic Zone are: larger fish, fish-eating birds, seals, sharks, human fishermen Producers if the Neritic Zone are: phytoplankton or autotrophic producers, and zooplankton, or heterotrophic producers
The main components of a wellhead include the casing head, tubing head, and Christmas tree. The casing head provides support for the casing strings and seals off the wellbore. The tubing head provides support for the production tubing and allows for access to the well. The Christmas tree is a series of valves and fittings that control the flow of fluids from the well.
The primary prey of orcas in the wild are fish, seals, sea lions, and sometimes even whales.
