What is ISO 10426‑3 – Petroleum and natural gas industries about?
ISO 10426 is an international standard on petroleum and natural gas industries. Natural gas is used in many industrial processes that produce materials and good ranging products. Petroleum is used to provide heat, light, plastics and transportation.
ISO 10426‑3 is the third part of ISO 10426 that provides procedures for testing well cement and cement blends for use in the petroleum and natural gas industries in a deepwater environment, or areas with a low seafloor temperature, or areas where low well temperature exist.
NOTE 1: ISO 10426‑3 excludes the mitigation of shallow water flow in deepwater wells.
NOTE 2: Deepwater is usually regarded as water of depths exceeding 400-500m.
Who is ISO 10426‑3 – Petroleum and natural gas industries for?
ISO 10426‑3 on petroleum and natural gas is applicable to:
- Petroleum and natural gas industries
- Gas companies
Why should you use ISO 10426‑3 – Petroleum and natural gas industries?
Petroleum provides transportation, heat, light, plastics, and an abundance of other uses as fossil fuel is easy to extract. Natural gas provides warmth for cooking and heating, and it fuels power that provides electricity to homes and businesses. It also fuels many industrial processes that produce materials and goods ranging from glass to clothing and ingredient in products such as paints and plastics.
ISO 10426‑3 provides guidance in the case of a Deepwater cementing environment, several factors impact the thermal history of the cement slurry. These factors include water depth, mud-line temperature, geothermal gradient, the presence or absence of a drilling riser, drilling fluid temperature, ocean current velocity, presence of thermoclines, ambient sea-surface temperature, cement mix-water temperature, bulk cement temperature, cement mixing rate, cement heat of hydration, displacement rate, prior circulating and static event history, drill pipe size and mass, casing size and mass, and hole size.
By using ISO 10426‑3, you can ensure the testing of the cement formulation that reflect as closely as possible the actual temperature profile found during field cementing operations. Such cementations require critical and extensive pre-testing in order to successfully cement these walls.
What’s changed since the last update?
BS EN ISO 10426‑3:2019 supersedes BS EN ISO 10426‑3:2004, which is withdrawn. It includes:
- A clause on numerical pressure and temperature simulation has been added in order to allow accurate determination of the pressure and temperature schedules required for the various tests
- Strength determination at the casing shoe, the mudline, potential flow zones, top-of-liner and open- or cased hole plug and squeeze locations is treated separately
- Directions for sonic strength testing data reporting have been included
- The laboratory procedures for both sonic and destructive strength measurements have been expanded
- A clause has been added on thickening time simulations for liner cementations with and without the use of either liner-top packers or expandable liner hangers.
