Comprehensive Water Treatment
Water Conformance & Water Shut Off Polymer Flood
Currently in Colombia, it is evident amount of water that is produced in oil wells thataffects efficiency dand operating companies. For this reason, any technology that minimizes the amount of water or gas produced together with the crude oil produced would have a significant impact on energy consumption and in theproduction cost of oil.
There are many factors, such as the presence of areas with channels or areas of high permeability, fractures and water cones, which lead to an increase in water production, or leakage of fluids injected into the reservoirs.
​
In an attempt to block unwanted water production and increase the volumetric sweep efficiency of fluid injection. The industry has used polymeric gels with intercrossers. For the shut off toilet, the process involves the strategic injection of a gelling fluid in the well where water conization occurs.
In water conformance, the injection of the gels is done in an area of high permeability, where there are fractures or channels, restricting the flow in that area and redirecting the fluids to areas of lower permeability.
​
Therefore, WSO and WC treatments can be used to generate relatively large volumes of incremental oil production with low costs and selective treatments targeting small volumes, which extend the economic life of marginal and mature wells.
Reuse Water Efficiency (Success Story)
Environmental regulations limit the contribution of sulfates in effluents, leading the industry to seek the best technologies available for the reduction of sulfates.EXRO SAS has comprehensively developed a process that eliminates sulfates from water and generates clean water effluent for reuse or discharge.
​
This solution uses a two-stage separation using processes and technologies such as clarification, fat removal and nanofiltration equipment to reduce the concentration of sulfate in the water to values below 250 mg/L.
Process Description
Among the water treatment solutions with sulfates, the use of nanofiltration (NF) membranes generates a quality permeate anda solution with a rejection stream of high concentration of sulfate ions.
However, this technology requires a specific condition in the water: Zero fat content and the minimum possible suspended solids. To achieve this condition, EXRO worked on optimizing the clarification process, achieving removals of suspended solids in the order of 95% and identified a grease removal system through the walnut shell filter bed. One of the most important concerns in the use of technologies such as Nanofiltration (NF), is the use of rejection.
​
For this reason, EXRO SAS has designed a recirculation system adaptable to the quality of the water that changes as the dilution with the process water is carried out, maintaining the value of the sulfates at its maximum allowable, at the inlet of the equipment. .
With this technological solution, in addition to achieving regulatory compliance, you obtain a quality of water suitable for subprocesses, reducing the consumption of drinking water by an approximate flow of 48 m3/day.
