Effect of the use of production water of petroleum industry in agricultural and livestock activities
The total supply of available water in the country is 2.01 billion m3. From this flow, the petroleum industry has obtained permits from environmental authorities for a total of 67.5 million m3. This is equivalent to 0.00336 % of the total flow. On the other hand, the oil that is extracted from the earth is mixed with waters that are known as "production waters". These waters are part of the natural fluids of the reservoirs. In Colombia, for every barrel of oil, an average of 13 barrels of water are produced. The “production waters” can be treated and reinjected in the same formation to maintain the pressure of the deposits to increase the "recovery factor", they can also be treated and discharged to bodies of surface water or to the soil surface; or reinjected into the reservoirs as final disposal strategies. The "production waters" of the Orinoquia deposits, have a relatively low content of salts and dissolved solids, and do not have radioactive elements. These conditions generate opportunities: once those waters are treated, they could be reused in productive activities in rural areas, within the area of influence of oil fields. For these reasons Corpoica developed a series of research projects aimed at evaluating options for the safe use of these treated waters for the irrigation of pastures and as sources of water for cattle and poultry, among others. The effect of the application of treated production waters on different components of the ecosystem and on agricultural and livestock production systems was determined. The research was carried out in the department of Meta in the ASA Research Center (03º53’06” N and 73º35’04” W) and in the La Libertad Research Center (04º03’32” N and 73º27’59” W) located in Acacias and Villavicencio, respectively. The treated production water that was used came from the fields of Castilla and Apiay. A set of relevant variables of soil, water, crops and animals was selected. These variables were monitored and analyzed between the years 2011 and 2015. The results of this investigation indicate that the use of production waters and their application to the soil do not have significant effects on the physical and chemical properties of the soil. Neither do they have significant effects on the quality of the waters or on the health of animals and crops.
