20110097152HELICALLY-REINFORCED HORIZONTAL WATER-GATHERING PIPE HAVING MULTI-DIAMETER AND METHOD OF INSERTING THE HELICALLY-REINFORCED HORIZONTAL WATER-GATHERING PIPE - Provided are a helically-reinforced horizontal water-gathering pipe having a multi-diameter, which is used in a riverbed filtration system that is installed in a predetermined depth of a riverbed to receive filtered water that is filtered through an aquifer and transfer the filtered water to a collector well or a collector trench, the helically-reinforced horizontal water-gathering pipe including: drain pipes including a plurality of inflow holes through which the filtered water flows, wherein the drain pipes have different diameters and each of the drain pipes having a larger diameter is disposed near the collector well or the collector trench; and at least one reinforcing screw helically protruded along an outer perimeter of each of the drain pipes, and a method of inserting the helically-reinforced horizontal water-gathering pipe. Since the helically-reinforced horizontal water-gathering pipe includes the reinforcing screw on the outer perimeter of each drain pipe, the helically-reinforced horizontal water-gathering pipe may be directly inserted into and installed in the aquifer by rotating the helically-reinforced horizontal water-gathering pipe. Accordingly, the helically-reinforced horizontal water-gathering pipe is easily and quickly installed without having to use an out-casing. Also, the reinforcing screw improves a structural strength of the helically-reinforced horizontal water-gathering pipe, thereby increasing durability of the helically-reinforced horizontal water-gathering pipe. Moreover, since a diameter of the helically-reinforced horizontal water-gathering pipe increases toward the collector well, an inflow efficiency of the filtered water may be prevented from being deteriorated even when a length of the helically-reinforced horizontal water-gathering pipe is long.04-28-2011

20110305514ESPRIZ funnel system - The current system was initially designed to help reduce the environment impact on in the Gulf of Mexico, when an operation rig exploded in April 2010 and the BOP over the well did not react to cutoff of the Oil spill from the well to the sea. The leakage of oil at such depth in sea is hard to assess. In such cases controlling and collection of the spill is the first thing to do. The Espriz Funnel system is based on simple and logical principles and the operation is low cost and fast. The goal of the system consists of collecting the maximum quantity of leaked oil at seabed level to reduce environment impact. By implementing this idea between 90%-100% of leaked oil will be gathered under a funnel and conducted by pumps through a flexible pipe on sea level and then loaded into FPSO or tankers. The loaded fuel may be accompanied by sea water and separating is easy to do. By this method the contact between the leaked oil and the sea water will be reduced to minimum possible and practically the whole leaked oil will be collected, without contaminating the sea water. We can design and manufacture different models of ESPRIZ Funnels for different sea levels to increase the safety level of drilling operation and we suggest using this system as an essential safety regulation12-15-2011
