How does a subsea Christmas tree work?
Functions of a Subsea Xmas Tree Enable flow of the produced fluid from the well or the injection of water or gas from surface facility into the formation (called injection tree), including protection fluids, such as inhibitors for corrosion or hydrate prevention.
What is SCM subsea?
Subsea Control Module (SCM) A standard Subsea Control System package for the Oil & Gas industry providing monitoring and control of subsea assets.
What is subsea control module?
Subsea control module (SCM) is the interface between the control system and the tree. It is the main component of the tree-mounted control system. The SCM contains electronics, instrumentation, and hydraulics for safe and efficient operation of subsea tree valves, chokes, and downhole valves.
What is a subsea tree?
Used on offshore oil and gas fields, a subsea tree monitors and controls the production of a subsea well. Fixed to the wellhead of a completed well, subsea trees can also manage fluids or gas injected into the well. Subsea trees are used in offshore field developments worldwide, from shallow to ultra-deepwaters.
Whats the relationship between a spool and Christmas tree?
In petroleum and natural gas extraction, a Christmas tree, or “tree”, is an assembly of valves, casing spools, and fittings used to regulate the flow of pipes in an oil well, gas well, water injection well, water disposal well, gas injection well, condensate well, and other types of well.
What is the difference between BOP and Christmas tree?
Many times, the words Christmas Tree and Wellhead are used interchangeably; however, a wellhead and Christmas tree are entirely separate paces of equipment. A wellhead must be present in order to utilize a Christmas tree and is used without a Christmas tree during drilling operations.
What are subsea equipments?
Subsea is fully submerged ocean equipment, operations or applications, especially when some distance offshore, in deep ocean waters, or on the seabed.
What is a subsea well?
1. n. [Well Completions] A well in which the wellhead, Christmas tree and production-control equipment is located on the seabed.
How much does a subsea tree cost?
The global average cost of a subsea tree is $5.5 million.
What is the casing spool?
1. n. [Well Completions] A wellhead component used in flanged wellhead assemblies to secure the upper end of a casing string. Casing spools or bowls are available in a wide range of sizes and pressure ratings and are selected to suit the specific conditions.
How do wellheads work?
Simply put, a wellhead is a system of spools, valves, and assorted adapters that used to provide pressure control of a production well. Its primary purpose is to provide a suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment.
Is a BOP part of a Christmas tree?
Many times, the words Christmas Tree and Wellhead are used interchangeably; however, a wellhead and Christmas tree are entirely separate pieces of equipment. A wellhead must be present in order to utilize a Christmas tree and is used without a Christmas tree during drilling operations.
What is a subsea tree mounted system (SCM)?
The SCM contains electronics, instrumentation, and hydraulics for safe and efficient operation of subsea tree valves, chokes, and downhole valves. Other tree-mounted equipment includes various sensors and electrical and hydraulic connectors.
Where is the subsea control module and production tree located?
The subsea control module and production tree are generally located in a remote location relative to the surface control equipment.
What is a subsea control module (SCM)?
The typical SCM receives electrical power, communication signals, and hydraulic power supplies from surface control equipment. The subsea control module and production tree are generally located in a remote location relative to the surface control equipment.
