Fracking manifold is a high-pressure manifold used in oil well fracturing operations.

Casing hangers are divided into two categories: threaded type (mandrel type) and cava type.

The casing head is a component that connects the casing and various wellhead devices: to support the gravity of the technical casing and the oil casing, to seal the annular interstitial interstitial of each layer of pipe, and to install the blowout preventer.

Oil production trees, also known as well trees or oil well installations, are important installations used to extract underground oil and gas.
