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 co...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 a...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 product...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 ca...Read more -

Oil And Gas Formation And Production
Oil and gas are formed from the remains of organisms that are decayed in the sedimentary rock alongside with the minerals of the rock. When these rocks are buried by overlying sediment, the organic matter decomposes and converts to oil and natural gas through bacterial p...Read more -
Growth In The Pipeline… a Pipe And Control Line Market Outlook
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...Read more -
The Most Common Reasons For Running Casing In a Well
The Following Are The Most Common Reasons For Running Casing In a Well: protect fresh-water aquifers (surface casing) provide strength for installation of wellhead equipment, including BOPs provide pressure integrity so that wellhead equipment, including BOPs, may be clo...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 pressuriz...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. Sinc...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...Read more
