51316-7106-Compatibility Behavior of Elastomers for PCP Applications

A compatibility study of two elastomers with low and high nitrile content was done with the aim of understanding the performance of elastomeric materials used in progressive cavities pumps in environments such as H2S, CO2 and different crude oils to simulate real conditions in the lab.

With the aim of understand the performance of elastomeric materials used in progressive cavities pumps to face operational conditions presented in Venezuelan oil wells it was carried out a compatibility study with a nitrile rubber in environments such as H2S CO2 and different crude oils to simulate real conditions in the lab. This study is based in the evaluation of the mechanical behavior of the elastomers before and after being in contact with different fluid and gases. NACE and ASTM standards were used to evaluate mechanical properties of the elastomers such as yield strength elongation at break Shore A hardness permanent deformation and volumetric swelling. It was employed characterization techniques such as thermal gravimetric analysis (TGA) and scanning electron microscopy (SEM). The effect of crude oils hydrogen sulfide (H2S) and carbon dioxide (CO2) in the elastomer helps to predict the performance behavior of the material when it is in service. Upon completion of the different evaluation techniques it was observed how different fluids conditions (Temperature H2S and CO2 concentration partial pressure etc) affect the mechanical properties of the elastomers studied. It is recommended to continue the evaluation with different elastomers which provide a range of support to various aggressive environments to which the material is subjected during its operation.
