The H2S can be find naturally in crude oil and natural gas, furthermore can be find dissolved in wáter, it is formed by a bacterial decomposition of organic matter, for example the sulfate-reducer bacteria which produce H2S in its metabolism. The H2S is a toxic gas. Heavier than air, flamable, colorless with the characteristic smell of rotten eggs, levels higher tan 100 ppm puts life and health at risk.
AZBIAS offfers adequate formulations according to the process to avoid health risks associated to H2S and reach the crude oil quality specifications.
The pumping process of crude oil créate turbulance that cause volatilization of the lighter fractions, the pumps produce cavitation and this is main cause of equipment failures, the water that contains the crude oil could cause foam when the crude oil goes from one state of equilibrium to another for example from the well to a separator, this sudden changes liberate water and some volatil liquids in a steam form generating foam.
AZBIAS offers products to prevent the creation of foam and avoid the prematury fail of pumping equipments.
During production process emulsions are form by agitation along all the system, an emulsion is the mixture of two immisible liquids like wáter and oil, it is stabilized by natural and synthetic emulsifier agents, there are not two equal emulsions and break it can be a complex task.
AZBIAS offers emulsion breakers for water in oil such as oil in water. To guarantee the efectiveness of the treatment It is selected and formulated for each particular case, usually are made at field with fresh emulsions. We have experts for analize the system at field and bring the adequate chemical solution that achieve all the necessities of sale.
The corrosion inhibitor is used to protect the storage equipments and pipe lines agains corrosion, because the metal susceptibility in environments that accelerete the loss of wáter, H2S and other contaminants.
AZBIAS offers chemical products to inhibit the reactions of different species of corrossion and give protection to facilities.
Debido a los cambios en las propiedades de los fluidos producidos en los yacimientos There are some changes in the fluids produced in oil reservoirs it could be because of aging or in the interventions to increase the production, all this cause mineral depositions because the water oversaturation and the minerals deposit all over the wall inside the line pipes, valves,tanks and treatment equipments, produving diameter reduction and flow restriction in equipments.
AZBIAS has a range of products to prevent the deposition of mineral scales also rpoducts to dilsolve scales once are formed, wáter characterization to determines the kind of scale and the implementation of a tratment program to increase production and reduce costs because cleaning and removing scales.
The H2S is found naturally in crude oil and gas, also can be found dissolved in water it is formed by bacterial decompostion of organic matter, for example sulfate-reducing bacteria (BSR) that produce H2S in their metabolism. The H2S is a toxic gas, heavier than air, flammable, colorless and with a characteristic smell of rotten egg, higger levels than 50 ppm puts health and life at danger.
AZBIAS offers formulations appropiate to the needs, to avoid health risks associated to H2S and achieve quality specifications of the crude oil.
Viscosity is an oil property that most be modified because of the difficult for moving it, pressures drops, deficient pumping, high loads in the production pipelines, etc.
AZBIAS offers formulations according the field needs, making transportation more efficient, improving viscosity allows to give more value to light crude oil and also reduce intervention to equipments and improve production.
Paraffins are part of the chemical composition of the oil their presipitations and deposition occurs such along the production system when the thermodinamic equilibrium conditions change, it causes problems from the reservoir it reduce the rock permeability, reduce diameters in production pipelines, separators, tanks, etc Causing a restriction in crude oil flow and bringing as a consecuence a lost in production.
AZBIAS offers inhibitor and dispersant products suitable for the system to avoid deposition of paraffins in the production equipments.
The crude oil in its natural state is a mix of hydrocarbones of different weights and structures that can variate from one deposit to other, the bitumen (also know as alphantenes) are part of the crude oil composition and are consider as the heaviest fraction of the crude oil those are stable to the own conditions of pressure and temperatura of the reservoir, when there exist a physical-chemical disturbance that desestabilizes the balance in particles, the asphaltenes tend to form agregates that precipitate and stick in walls of pipeline productions, transport, separators, etc, restricting flow of crude oil and ginving a low of production as a consecuence.
AZBIAS offers asphaltenes dispersant and inhibitors according to the particular field conditions to improve production, dicrease in the decliniation rate, a reduce in deferred production and frecuence of cleaning.
he destruction of a material by an electrochemical reaction with the own environment is known as Corrosion, the speed of it depends on many factors physical and chemicals, it is one of the main problems in cude oil and gas production facilities, transport and storage equipment, etc. and if it is not atended early could cause catastrophic failures.
AZBIAS offers formulations for inhibitor according to the particular conditions of each field, to give protection that facilities required to achieve operability of your process with a higher efficience and safety.
Because of changes in fluids properties produced by a mix of incompatible formatioons, aging, water inyection, pressure and temperature changes in the well and at surface equipments is produced the accumulation of minerals inside the walls of pipelines, treatment equipments, tanks, valves, etc, generating with this diameter reduction, flow restriction and less production.
