Abstract

Formation damage causes the reduction of reservoir permeability and therefore reducing the productivity and injectivity of wells. One of the root causes of formation damage is the formation of scale which is either inorganic or organic precipitation. Inorganic scaling can occur in the well tubing and near well bore formations of production and injections wells. Two different types of zeolite which are clinoptilolite and chabazite were used in this study to mitigate the inorganic scaling which causes the formation damage. The objective of this study is to analyze the potential of clinoptilolite and chabazite to remove barium and sodium ions via adsorption. The effect of effective permeability of fluids before and after treatment with zeolite was also investigated. The degree of ions sorption of zeolite will be measured based on the value of the ions concentration measured by Atomic Adsorption Spectrophotometer. Bench Top Permeability System was used to measure the effective permeability of the fluids. The results obtained were analyzed to assess the potential use of zeolite in mitigating the inorganic scale. Results from the present project indicate that both clinoptilolite and chabazite has the capability to adsorp sodium ions. However those types of zeolite do not have the capability to adsorp barium ions. After the zeolite treatment, there were no significant effects that shown the reduction of the effective permeability of the fluids. This study found that raw natural zeolite such as clinoptilolite and chabazite do not exhibit high degree of potential in mitigating the formation of inorganic scales.
