Abstract
Sand control has traditionally been one of the biggest problems affecting production facilities and the design of surface equipment leading to escalation of project costs. With industry venturing into deeper waters and rising crude prices it's essential to develop complete and forget techniques for offshore locations most probable to produce sand. Hence a proper analysis for sand prediction and management has been at the forefront in research by many companies.
The most viable alternative today being gravel packs although requiring constant attention as seen through various literature reviews. We emphasized on the chemical consolidation technique for sand control which has been overlooked but is promising considering escalating maintenance costs. We would like to introduce a new resin consolidation system which is cost effective and withstand very high pressures and temperature ranges from 50 °F to 450 °F. The resin consists of Aromatic Polyesteramide and Tri-alkoxy organo silane based consolidation system. The chemicals combine together on contact with formation water to essentially hydrolyze it at the sites to form a strong silanol adhesive which bonds the grains together thus giving a highly strong bond. The highlight of the paper is the process of consolidation which is site specific thus preventing the considerable loss in porosity and permeability as is generally seen in chemical consolidation systems. The paper describes the complete properties of the polymer resin system and the process of consolidation with the new system. In addition it describes the advantages of being environmental friendly and easier to handle with comparison to certain furan based resin systems that are currently used in the industry and have handling issues.
