FRAC WATER BLENDING SYSTEM
A water blending system and associated method for a gas shale well is provided, which includes a first inlet pipeline that receives water from a freshwater source. The first inlet pipeline has a first valve. A second inlet pipeline receives flow back water and has a second control valve. A third pipeline receives water flow from the first and second pipelines. The first pipeline has a salination level detector, the third pipeline flowing water into a tank; wherein the water flow of the first and second inlet pipelines is adjusted based on a salination level detected by the salination level detector.
1 . A water blending system for a gas shale well, comprising:
a first inlet pipeline receiving water from a freshwater source, the first inlet pipeline having a first valve;
a second inlet pipeline receiving flow back water, the second inlet pipeline having a second control valve;
a third pipeline, receiving water flow from the first and second pipelines, the first pipeline having a salination level detector, the third pipeline flowing water into a tank.
2 . The water bending system of claim 1 wherein the water flow of the first and second inlet pipelines is adjusted based on a salination level detected by the salination level detector
3 . The water blending system of claim 2 wherein the first and second inlet pipes meet the third pipeline at a junction.
4 . The water blending system of claim 3 wherein the third pipeline has a siphon tube exterior thereto.
5 . The water blending system of claim 4 wherein the first and second valves may be bypassed through respective first and second bypass lines.
6 . The water blending system of claim 5 wherein the third pipeline has a plurality of agitation plates.
7 . The water blending system of claim 6 wherein the first and second pipelines have respective first and second flow meters.
8 . The water blending system of claim 7 wherein the first and second flow meters are magnetic flow meters.
9 . A method of providing frac water to a tank, comprising:
receiving a flow of fresh water from a first pipeline, the first pipeline having a first control valve;
receiving a flow of flow back water from a second pipeline, the second pipeline having a second control valve;
combining the flow of fresh water from the first pipeline and flow back water from the second pipeline into a third water flow;
determining the salination level of the combined water flow, and:
if the salination level is above a maximum level, then increasing the first pipeline flow or decreasing the second pipeline flow; or
if the salination level is below a minimum level, increasing the second pipeline flow or decreasing the first pipeline flow.
10 . The method of claim 9 wherein the first pipeline flow is set at a maximum level, and if the salination level is greater than the maximum level, the second pipeline flow is reduced.
11 . The method of claim 10 wherein the second pipeline flow is set at a maximum level and if the salination level is greater than the maximum level, the first pipeline flow is increased.
