Sand control in horizontal wells The evolution of sand control from historical water wells to recommendations for 15‚000 ft+ horizontal oil/gas wells. This summary article backgrounds the need for formation sand entry prevention in downhole producing wells from man ’s first dumping of rocks into water wells drilled with rock or iron tools. Thousands of years later‚ the oil/gas industry invented basic gravel pack and sand screen methods to prevent inflow of unconsolidated formation sands.

been investigated in the past‚ but these were not readily acceptable for commercial production so far. Systems based on Dowicil 150‚ LA-TZ and LA-BZ were found to be unsuitable for block rubber production due to the adverse effects on CV (constant viscosity) properties‚ PRI (Plasticity Retention Index) and colour. There is‚ therefore‚ an urgent need to develop a better preservative system to replace those currently used as they can eventually become unsuitable due to the constraints of future regulatory

Lab #4 The Synthesis of Organic Polymers CHM2123‚ Section C October 21‚ 2014 Introduction: Organic polymers are macromolecules that are composed of smaller molecules called monomers. There are two main groups of polymers: natural polymers and unnatural (synthetic) polymers. Natural polymers include proteins such as cellulose and starch and are a necessity for our existence. On the other hand‚ synthetic polymers such as the polycarbonate in our lab goggles
