Casing Head

Specialized large-diameter pipe lowered into an open hole and cemented in place. Casing

conform to latest version of API Specification 5CT, API Specification 5B and other related

standards.

Casings are available in standard API configurations with all sizes from 5" to 133/8" in grade

H40, J55, N80, L80, C90, P11O and Q125

Technical Performance

1. - High thread bonding strength with good anti-thread gluing ability.

2. - The steel yield strength is bigger than API standard.

3. - Big OD size, high steel grade with full size available.

Christmas Tree & Tubing Head

ChristmasTree:is an assembly of valves, spools and fittings for an oil well, and to design todirectand control formation fluids from the well. It can provide inlet for production tubingstrings, including all components above the tubing head adapter. Christmas tree assemblies

can constitute many different kinds of combinations in order to meet any special requirement.

Based on their different functions, Christmas trees can be classified into such special

Christmas trees as oil production (flowing and artificial lift) Christmas trees, gas (natural gas

and various sour gas) production Christmas trees, water injection Christmas trees, thermal

recovery Christmas trees, fracturing Christmas trees and acidizing Christmas trees. Different

pressure ratings serialize Christmas trees.

The gas production Christmas tree and tubing head are mainly used to produce gas and inject

gas. The relative density of natural gas is low and gas column pressure is low, while well head

pressure is high and liable to leakage regardless of gas production and gas injection.

Sometimes natural gas contains corrosive media such as H2S and CO2. Therefore, the gasproduction Christmas tree calls for rigid requirements on both its materials and its sealing

characteristics. For the sake of safety, two gate valves are used on the tubing and casing

respectively. Some gate valves to be used on high pressure and ultra-high pressure gas wells

are integrated valves manufactured from high quality forged steel.

The pressurization parts of the Christmas trees and tubing spools sold by Sapwells Global are

made of forged or special smelted forging, so it is high-pressurization safety and so on.

Scope of supply:

Working pressure: from 2,000psi to 20,0000psiNominal diameter: from 2.1/16" to 5.1/8"

Working medium: crude oil, gas, drilling fluid, gas contained H2S, CO2

Working temperature: -46C to 121C (L U)

Material class: AA, BB, CC, DD, EE, FF

Specification level: 1-4

Performance requirement: 1-2

To complete with air or hydraulic safety valve at option.

Tubing Spool

1. Tubing head structure

Tubing head is usually a spool with both flanged ends, which is set on the top flange of casing

head to hang tubing hanger and seal the annular space between the tubing string and oil-layer

casing and which consists of tubing head spool and tubing hanger.

2. Functions:

1) Hang the tubing string inside well;

2) Seal the annular space between tubing and casing;

3) Give a crossover to connect casing head downwards and to connect Christmas tree

upwards;

4) Provide both side outlets in tubing head spool body through which to execute injection andwellwash operation.

3. Tubing hanger

Tubing hanger is an assembly to support tubing string and seal the annular space between

tubing and casing, which is connected with tubing and seated into tubing hanger spool by

tubing gravity. It is convenient to operate and replace wellhead so that it is widely used for

intermediate depth well and common well.

Design features:

Fabricated with BT secondary seal, and could be field mounted by cutting casing pipe to

accommodate the seal height.

Tubing hanger and top flange are designed to run cable through.

Several control ports are available for connecting pipeline.

Sapwells Global sells tubing head spool manufactured in full accordance with API 6A, the

body is made of forged or special smelt steel, providing high bearing strength, safety and

reliability. Side outlets could be line pipe thread or studded, studded side outlet is machined

with 1.1/2" female thread.
