Downhole Coupon Holder provides metal loss measurements.

Press Release Summary:




Withstanding temperatures to 302°F and pressures to 10,000 psi, DCHA (Downhole Coupon Holder Assembly) indicates general corrosion behavior patterns and acts as secondary metal loss measurement of downhole tubing when used in conjunction with DCMS Downhole Tool for corrosion monitoring. Solution holds up to 9 coupon holders, including Bent Beam, Strip, and Cylindrical corrosion coupons. Three types of coupon holders can be mixed and matched according to corrosion effects being evaluated.



Original Press Release:



New DCHA(TM) Downhole Coupon Holder Assembly Provides Metal Loss Measurements of Downhole Tubing



Rohrback Cosasco launched the new DCHA Downhole Coupon Holder Assembly for downhole well corrosion management. The DCHA will indicate general corrosion behavior patterns and act as a secondary metal loss measurement, when used in conjunction with the DCMS Downhole Tool for corrosion monitoring. Coupon metal loss data from the DCHA samples can be correlated with ER probe metal loss data and temperature data, from the Downhole tool, to effectively analyze the condition of the downhole tubing.



The DCHA was developed to test the effects of different types of corrosion on downhole tube materials, including general corrosion, crevice corrosion, stress corrosion, and pitting in downhole conditions. The DCHA holds up to nine coupon holders, including Bent Beam, Strip, and Cylindrical corrosion coupons. The three type of coupon holders can be “mixed and matched” according to the type of corrosion effects you are evaluating. With the DCHA tool body made of highly corrosion resistant 17-4 PH stainless steel, it is designed to with stand temperatures up to 302°F (150°C) and pressures up to 10,000 psi.



Corrosion inhibitors are a cost-effective means of controlling corrosion in the downhole tubing of existing wells when properly tested and monitored. The Downhole Coupon Holder Assembly (DCHA) used solely or in conjunction with the DCMS™ Downhole Tool provides metal loss data from within hostile downhole environments and is used to test the efficacy of downhole corrosion inhibitor treatments.



The DCHA Downhole Tool is available for purchase and rental. For more information and specifications on the DCHA™ Downhole Corrosion Monitoring Tool for well corrosion management visit www.cosasco.com.
