Tubing hanger and tree with horizontal flow and annulus ports

A well production assembly located at an upper end of a string of tubing extending into a well, comprising:

• a production tree having a longitudinal axis, an axial bore and a lateral production passage, the lateral production passage having an inlet at the bore and extending laterally through a sidewall of the production tree;
• a tubing hanger landed in the bore and adapted to be located at an upper end of a string of tubing, the tubing hanger having a vertical production passage extending axially through the tubing hanger and a lateral production passage which extends laterally from the vertical production passage through the tubing hanger and has an outlet at the exterior of the tubing hanger which registers with the inlet of the lateral production passage of the tree;
• a vertical annulus passage extending through the tubing hanger from a lower end to an upper end of the tubing hanger offset from the vertical production passage, the vertical annulus passage having a lower end adapted to be in communication with a tubing annulus surrounding the string of tubing;
• a removable production plug installed in the vertical production passage above the lateral production passage of the tubing hanger;
• and
• a removable annulus plug installed in the vertical annulus passage.

A well production assembly, comprising:

• a production tree having a longitudinal axis, an axial bore, and a lateral production passage, the lateral production passage having an inlet at the bore and extending laterally through a sidewall of the production tree;
• a tree seat ring installed within the inlet of the lateral production passage of the tree, the tree seat ring having on an inward facing side a tree seal area which is flat and inclined relative to the axis;
• a string of tubing extending into the well;
• a tubing hanger connected to an upper end of the string of tubing and landed in the bore, the tubing hanger having a vertical production passage extending axially through the tubing hanger and a lateral production passage which extends laterally from the vertical production passage through the tubing hanger, the lateral production passage of the tubing hanger having an outlet at the exterior of the tubing hanger;
• a tubing hanger seat ring installed the outlet of the lateral production passage of the tubing hanger, the tubing hanger seat ring having a tubing hanger seal area located on an outward facing side of the tubing hanger seat ring which sealingly mates with the tubing hanger seat ring;
• a vertical annulus passage extending axially through the tubing hanger offset from and parallel to the vertical production passage, the vertical annulus passage having a lower end in communication with a tubing annulus surrounding the string of tubing and an upper end at an upper end of the tubing hanger;
• a removable production plug installed in the vertical production passage above the lateral production passage;
• and
• a removable annulus plug installed in the vertical annulus passage.

A well production assembly comprising in combination:

• a production tree having a vertical axis, an axially extending bore, and a lateral production passage extending from the bore through a sidewall of the tree transverse to the vertical axis;
• a generally upward facing shoulder formed in the bore;
• a tree auxiliary passage extending through the sidewall of the tree and having an auxiliary connector located at the upward facing shoulder;
• a string of tubing extending into a well;
• a tubing hanger which lands sealingly in the bore and is connected to the string of tubing, the tubing hanger having a lateral production passage extending from an axial production passage, the lateral production passage aligning with the lateral production passage of the tree;
• and
• a tubing hanger auxiliary passage extending through the tubing hanger, having an auxiliary connector which telescopingly and sealingly mates with the auxiliary connector in the tree when the tubing hanger lands, to communicate the tree auxiliary passage with the tubing hanger auxiliary passage.
