Abstract
A chemical injection system directed at lower completions. The system includes a tubular stinger that is anchored within a upper region of a well but traverses into the lower completion. Thus, a platform is provided for a chemical injection line running from surface to the lower completion. As a result, chemical injection may be directed right at a sand screen and other scale prone features of lower completions.
Claims26
A chemical injection system comprising:
- an upper completion assembly disposed in a well;
- a lower completion assembly adjacent said upper assembly in the well;
- and
- a tubular stinger anchored in said upper assembly and providing fluid communication to said lower assembly for delivering chemical injection thereto.
1 more element
A chemical injection system comprising:
- an upper completion assembly disposed in a well and accommodating a production tubular;
- a lower completion disposed adjacent said upper assembly in the well;
- a shroud about the production tubular and coupled to said lower completion for maintaining flow management between the production tubular and said lower completion assembly;
- and
- a tubular stinger anchored in said upper assembly and providing fluid communication to said lower assembly for delivering chemical injection thereto.
2 more elements
