Sand production is a big challenge for the upstream oil and gas industry .The sand particles that being produced together with reservoir fluid does not have any economic value .Besides ,it will cause severe production restriction ,erode tubular goods including downhole pumps and surface pipeline and equipment .With that ,sand control method need to be apply during the completion and production stage .The purpose of having sand control is to prevent unwanted solids being produced into wellbore ,completion string and surface facilities. But ,the conventional sand control likes gravel packing and screen are less effective and not 100% isolate the sand particles from the wellbore. Nowadays ,a lot of technology being introduced in the market to control this problem .Different company will introduce different method .Some of the technology that being introduced are based on some concepts likes chemical injection or improvement from the conventional method .The brand of method might be different because of different company will have different name. But, the similarities from all this method are their concept. In this paper ,the new technology that will review are sand aid or also known as zeta flow and through tubing gravel pack ( TTGP ).Sand aid are chemical injection and it’s being introduced in conjunction to improve the resin injection method .Both method are using the chemical but the different is their chemical fluid being inject and properties. Based on the real case study ,sand aid are more easy to handle compared to resin injection .This will be explain more in the next section.
