At present, with the increasing in demand for natural gas, all gas production companies are increasing their efforts in natural gas exploration and development. Corrosion is one of the problems during the wet gas transporting, and this can be solved by adding corrosion inhibitor(CI) in most case. However, there are no standards for the Cis performance used in gas gathering and transportation pipelines, which may lead to some gapsbetweentheR&Dscientistsandtheneedsofcorrosioninhibitorusers. Based on the demand of some gas production companies for the CIs, this paper puts forward the performance requirements and corresponding indexes of Cis for natural gas gathering and transportation system, and given some advice on the evaluation method.

Laboratory Evaluation of Metalized Coatings for Use on Reclamation Infrastructure

Product Number: 41213-788-SG

Author: David Tordonato, Allen Skaja

Publication Date: 2013

$20.00

Metalizing is not a new technology. It has been in use since the 1930s. Although it has seen limited use in comparison with conventional coatings, this is primarily due to economics. In past years, application rates for metalized coatings have been slow, making the process an expensive alternative to conventional coatings.

Laboratory Evaluation of Scale Inhibitors Used in OTSG Boilers for Control of Silica Related Scale

Product Number: 51323-18761-SG

Author: Dong Shen, Kung-Po Chao, Swamy Margan

Publication Date: 2023

$20.00

The production of heavy oil or bitumen depends upon continuous steam injection to fluidize the oil in the formation. Most of the boilers used in steam generation to enhance oil production are gas-powered once-through-steam-generation (OTSG), because OTSG’s can tolerate hard water and are relatively easy to maintain. Since an approximate 80% of feedwater is vaporized in a single pass, silica/silicate scales could form in the OTSG boiler if the silica content in the feedwater is not well controlled.

Laboratory Experimental Methods for Estimating Inhibition Performance of Corrosion Inhibitor for Deepwater Natural Gas Pipeline

Product Number: 51319-13321-SG

Author: Yun Wang

Publication Date: 2019

CO2 corrosion has become a problem that can not be ignored for the deepwater natural gas pipeline. At present this is difficult to simulate the low water content and the high gas flow velocity for natural gas field in the deep water by the traditional evaluation method of corrosion inhibitor in the laboratory and the accuracy of experimental results is questionable. In this paper laboratory simulation of actual natural gas field conditions was carried out using traditional rotating cylinder electrodes and self-made wet gas flow loop via considering the wall shear stress and mass transfer function as the hydrodynamic parameters to equivalent actual working conditions and laboratory conditions. The effect of corrosion inhibitor in high gas flow velocity was evaluated by using the weight loss test the Microcor ER probe and the self-made electrochemical probe respectively. By comparing the evaluation results of above methods the advantages and disadvantages of each method are analyzed at same time the most suitable method and process for the evaluation of corrosion inhibitors are screened and formulated in deepwater natural gas pipelines. In addition it provides the theory and data support for the evaluation of the corrosion inhibitor in deepwater natural gas field.

Laboratory experiments vs Field experience – Localized corrosion performance of lean duplex stainless steel UNS S32202 in municipal wastewater treatment plants

Product Number: 51323-19159-SG

Author: Audrey Allion, Charles David, Benoit Emo, Nicolas Larché

Publication Date: 2023

$20.00

Thanks to their good corrosion resistance and ease to shape and weld, austenitic stainless steel grades (e.g. UNS S31603) are used as standard materials for the construction of municipal wastewater treatment plants (WWTP). The main factors influencing the corrosiveness of the fluids in WWTP are halides concentration (more specifically chlorides), H2S content, low pH, temperature and their combined effects.

In municipal wastewater streams, chloride content, known to be one of the critical agents affecting the stability of protective passive layers for stainless steels2, is usually around 50-200 mg/L and in this content range does not present major issues for the austenitic grade.

Laboratory Investigation Of Coating Impedance In Controlled Environments Using A Two-Cell Field Test Method

The recent development of ASTM D8370-22 provides a field-applicable technique for measuring impedance on protective coatings. The test method expands the use of electrochemical impedance spectroscopy (EIS) beyond the laboratory and standardizes the approach for various applications to polymeric coatings on conductive substrates, e.g., barrier coatings on steel structures. Example applications include condition assessments and quality control testing.

Laboratory Investigations into the Edge Protection of Organic Coatings

Product Number: 41210-555-SG

Author: Sascha Buchbach, Andreas W. Momber

Publication Date: 2010

$20.00

The presentation reports about a nationally funded 3-year R&D project on the effects of edge geometry and coating type on the corrosion protection performance of organic coatings on edges with particular attention to ballast water tank applications. Core of the presentation is the description of the testing scenarios, the introduction of three assessment methods, and the discussion of the results. Testing methods included the long-term testing of samples in a specially designed IMO chamber, the utilization of electric impedance spectroscopy and DFT measurements on polished cross sections of coated edges.

Laboratory Study of Internal Corrosion and Cathodic Protection Concerns Related to Offshore Monopile Structures

Product Number: 51323-18894-SG

Publication Date: 2023

There have been several studies and publications over the past decade that clearly illustrate how initial assumptions about monopile interiors being perfectly sealed compartments were not correct in practice. Oxygen ingress through various points in the monopile contributes to persistent internal corrosion, and planned inspections are also opportunities to introduce fresh oxygen into the monopile. The replenishment of oxygen has been found to continue the corrosion reaction between the monopile wall and entrapped water.

Scaling is an important factor affecting oilfield production. The main reasons for scale formation are usually either the mixing of incompatible waters in production flow systems, for example, a formation of brine and seawater injected for maintaining downhole pressure, or changing the
reservoir conditions such as temperature, pressure, and brine pH, among others1,2. Carbonate scaling is dependent upon the equilibrium between bicarbonate, carbonate, and carbon dioxide relative to changes in the temperature and pressure3,4. Scale can deposit on almost any surface,
so that, once a scale layer is formed, it will continue to become thicker unless treated. Scale can block pore throats in the near-well bore region or in the well itself, causing formation damage and loss of well productivity.
