Production stimulation of heavy oil – PEMEX technology test NodalAnalysis

We have developed and licensed a non-ionic surfactant based on mono-terpenes that efficiently recovers hydrocarbon flow, removing axial reservoir damage surrounding production wells.
We began performing nodal analysis of hydrocarbon going through every stage of production, from the reservoir, passing to the well bore and through the production tubing, observing a radical change in petrophysical states of crude oil.
Developing chemical and mechanical procedures, our goal was to keep near-constant the viscosity values of crude oil inside the reservoir, while flowing to lower pressures and temperatures, to the wellbore, tubing and surface.
The outcome is a mixed service of reservoir and hydrocarbon lab study, formulation, stimulation planning and intervention that will allow a low performance well to reach its expected potential, usually provided by the Reservoir Engineering Lead.

Water Injection Well Stimulation – South America

We began modelling a Choke Model (restriction modeling) in South America where a state-owned oilfield had decreased their light oil production due mainly to not being able to handle high water cuts, that produced more water than the field could handle.
The field used a major oil pit to hold the crude and inject water from the bottom of the pit. The volumes handled were so high that the water injected was too polluted with oil and there was no time to hold for oil-water separation.
First, we mixed the pit with a highly effective surfactant dehydration additive to rapidly create a phase separation on the pit, thinning the water to a maximum. But because of poor quality water historically being injected into the reservoir, the injectivity of the well dropped and injection could not be achieved. Using the oil samples from the pit we determined a terpene-based formula to stimulate the injection well. After two days of formula injection, the well increased injectivity by hundreds percent, allowing the field to fully drain the oil pit and increase production to field highest efficiency. Once the field achieved maximum performance we were able to provide the field with the custom surfactant to keep oil pit separated and let the well inject higher volumes of water.

Flow additive success – Mexico

FlowTankA high performer - heavy oil production well had their hydraulic pump mechanism changed and the well did not recover to production. Once called by the operator, we analyzed the data and assessed that the well was brought to production too fast and production dropped rapidly. We began a lab analysis to the oil to understand its behavior under different environments. We were able to adapt our leading flow additive product and develop a successful re-opening procedure for the well, adding small volumes of the additive and staging the well opening and measuring the results until it achieved higher-than-expected oil flow. Our flow additive was also able to increase production in a very small dosage. As a field test we supplied a year worth of additive and the well achieved a sustained 200% production from its previous higher rate.
