A head for a well tubular. The well tubular head includes features that may be applied to a casing head or a tubing head. The well tubular head includes a bowl tubular reversibly connected with a casing connector. The bowl tubular is adapted for connecting with an uphole component of an equipment stack or other system. The bowl tubular includes a hanger profile for receiving a casing hanger or tubing hanger. The casing connector is adapted for connecting with the casing. The bowl tubular and the casing connector may be replaced independently of each oth-er. Removable connection points for flow lines may be includ-ed on the well tubular head to facilitate changing flow lines or flow line connection points. The bowl tubular may include a dri-ve system for rotating tubing.

An injector head used in coiled tubing systems including at least two opposed counter-rotating chain loops having a first end and a second end, the chain loops having a chain. The injector head further includes a fixed drive sprocket disposed at the first end of a chain loop and a floating sprocket disposed at the second end of the chain loop. In the injector head, there is a force applied to the floating bottom sprocket to maintain the chain loop at a desired chain tension. Additionally, the injector head includes a tension cylinder that automatically maintains the chain loop at the desired chain tension.

A downhole protection apparatus, for use in protecting downhole control lines, comprises a sheath defining a channel configured to receive a control line. The sheath is configured to be attached to a tubing. In wellbore applications, the control lines associated with a tubing are inserted into the sheath such that the body of the sheath at least partially encompasses the control line and shields the control line from harsh downhole conditions which may include abrasive action from sand, proppants, wellbore cuttings and other debris. Therefore, the apparatus is configured such that after insertion of a control line into the channel, a body of the sheath protects the control line from an outside environment.

Method of simultaneous introducing of two or more than two chemical substances and/or water into a subterraneous hydrocarbon formation and/or control of the rate of chemical reactions of these substances, and a device for implementation of this method This invention relates to the method of simultaneous introducing of two or more than two chemical substances and/or water into a subterraneous hydrocarbon formation and/or control of rate of chemical reactions of these substances and/or water by introducing their controlled amount into a subterraneous formation containing liquid and/or gaseous hydrocarbons, particularly crude oil, shale gas or natural, below a dedicated packer for exploration and production of these hydrocarbons and simultaneous inserting of a dedicated data cable (3) for interconnection of the measuring and/or regulating components in the wellbore, where the said chemical substances and/or water are supplied into the wellbore at controlled rate through the free casing (5) by means of at least three mutually separated flexible tubing (2a,b) (flexible injection lines) or the combination of these flexible tubing (flexible injection lines) with the solid wellbore tubing, or by means of at least one flexible multi-channel tubing containing inside at least three fix-attached flexible tubing (channels) of smaller diameter leading into the space in the wellbore and/or pay zone below/behind at least one remotely-adjustable packer connected with the well head that, after reaching the required position, seals off space in the wellbore below the packer and the pay zone (16) against the space above the packer in the wellbore and up to the well head. The invention also includes a device for the implementation of this method.
