Infrastructure Protection: Injecting Chemicals To Inhibit Corrosion

Corrosion is a natural process, in which a metal gradually is destructed by a chemical or electrochemical process while contacted with its environment. Typical sources of corrosion are pH, CO2, H2S, chlorides, oxygen and bacteria. Oil or gas are called “sour” when the concentration of hydrosulfid... Read More

How To Select The Right Mass Flowmeter

For ten years it was quite common to take a mechanical flowmeter. With higher safety and security levels we expect from instrumentation for the oil and gas industry nowadays, a Coriolis flowmeter is the most logical and safest choice. The Coriolis flowmeter is a highly accurate direct mass and de... Read More

How To Deal With Risks Associated With Chemical Injections

There are various risks associated with chemical injections. Sometimes the injected chemicals do not have the desired effect, sometimes the process of deposition or corrosion just continues under injection. In case too much pressure is used for the injection, the production may be damaged. Or whe... Read More

Chemical Injections To Assure And Condition Flow By Preventing Build-ups

In order to prevent deposition typically inhibitors are injected. Depositions or build-ups in the oil and gas processes usually are asphaltenes, paraffins, scaling and hydrates. Of those asphaltenes are the heaviest molecules in crude oil. When they adhere, a pipeline can quickly plug. Paraffins ... Read More

Oil And Gas Formation And Production

In a globalised market, fragmentation in performance can be expected – in the pipeline and control line sector this is a key theme. Indeed, relative sub-sector performance differs not only by geography and market segment but also by water depth, construction material and environmental condi... Read More

Surface-Controlled Subsurface Safety Valve (SCSSV)

Control Line A small-diameter hydraulic line used to operate downhole completion equipment such as the surface controlled subsurface safety valve (SCSSV). Most systems operated by control line operate on a fail-safe basis. In this mode, the control line remains pressurized at all times. Any leak ... Read More

Downhole Chemical Injection Lines-Why Do They Fail? Experiences, Challenges and Application of New Test Methods Copyright 2012, Society of Petroleum Engineers Abstract Statoil is operating several fields where downhole continuous injection of scale inhibitor is applied. The objective is to protec... Read More

What Is Important In Selecting Pressure And Temperature Transmitters

Liquid compositions, temperature and pressure ranges, the flow, the location of an installation and the need for certificates are usually the basis for selection criteria. Chemical injection skids are often used on offshore platforms, where weight is very important. Since the chances of over-pres... Read More

The Role Of Chemical Injections

In the oil and gas industry we inject chemicals in order: • to protect the infrastructure • to optimize processes • to assure flow • and to improve productivity Chemicals are used in pipelines, tanks, machines and wellbores. It is crucial to avoid risks coming along with the injections. Too littl... Read More
