Asphaltene And Paraffin Solution; Understanding Oil And Gas Wells Problems

By Jeffrey Myers


It is not unusual for asphaltenes and paraffins to be talked about as one big topic. Even so, you need to know that these two distinct elements differ immensely when it comes to their composition, their behavior and also the conditions that often cause deposition. In order to find a lasting asphaltene and paraffin solution both elements should be looked at distinctively.

It is not cheap to treat chemical solutions. However, this is seen as a small price to pay, given the massive economic disadvantages of not addressing a concerns. These problems can affect the well and lease profitability and lead to a long list of operational problems. Oil and gas well companies could also count losses stemming from damaged formations and decreased production.

In order to control a concern, you must first understand its nature and what triggers it. Paraffins are made up of a range of molecular weight alkane and saturated hydrocarbons found in crude oil. When a paraffin structure is branched or normal it can be greater than C100 in size. The usual paraffins have a higher melting point than their branched counterparts of the same size.

Longer structures have more carbon and this gives them molecules that are larger in size and a higher melting point. In return, they are the first to emerge from a solution. The deposits of paraffin at the bottom will have higher molecular weight and for an issue to be addressed, the deposits must first be carefully analyzed.

Deposition can occur because of changes in temperature-pressure conditions or any other disturbance in the equilibrium. Skilled experts can help to conduct field tests that can assist in establishing whether a specific deposit is paraffin. Asphaltenes on the other hand have greater molecular weight, heavy metals and intricate structures containing O, N, S.

Asphaltenes are responsible for giving crude oil its color. For this reason black-oil crudes often contain more levels of asphaltene. This element has polar molecules that absorb to formation surfaces and increase the water flow. To find solutions, you must also understand that while asphaltene a colloidal dispersion and is insoluble in crude oil, paraffin is soluble.

While paraffin deposits melt, those of asphaltene decompose forming a coke-like deposit. Concern stemming from this can cause major operational problems in oil and gas well companies. Some of the concerns you may encounter include restricted flow, increased power costs and equipment bottlenecks. Because asphaltene and paraffin issues are unique in each region, you will need to invest in customized solutions.

You need a team of skilled experts to lend a hand in order to prevent buildups. There are proven preventative measures that can help to keep asphaltene and paraffin deposition at bay. Then again, an existing problem can also be addressed in order to boost tubular and equipment longevity, increase production and prevent expensive remediation procedures.
