Frequently Asked Questions

What if my skim oil is rejected due to high BS&W?

What are the main objectives Maxflow concentrates on when it comes to disposal wells?

Maxflow’s primary objective when taking over treatment of disposal well is 1 – provide adequate water clarity 2 – slow bacteria growth 3 – control pad/interface growth 4 – provide sellable skim oil off gunbarrel into oil sales tank without having to do additional treatment 5 – prevent high volume of filter sock change outs per shift 6 – maintain are lower well pressure for higher injection rates 7- scale and corrosion protection 8 – most important, customer satisfaction at the lowest cost possible

How do systems produce clean oil?

A proper running system along with effective chemical program should provide clean oil off gunbarrel into oil sales tank. Rule of thumb is to keep minimum of 2 feet of oil in gunbarrel at all times and skim anything above that. By doing this typically skim oil will be sales ready with no extra treatment required.

Is it possible to control pad/interface in my system?

Yes it’s possible to control and slow pad growth but almost impossible to prevent it from happening. The most common type of pad/interface especially in the Permian Basin and Eagle Ford consist of iron sulfide and solid residuals from flowback and produced water. If not properly treated the combination of iron sulfides and residual suspended solids from production wells along with gels and other completion fluids will bond together and begin to form pads. By using the right chemical program and constantly dissolving the iron precipitants this will prevent pads/interface from getting out of control.

Does having large pad/interface in my gunbarrels and water holding tanks affect my oil sales?

Yes having large pads/interface will definitely affect your oil sales. Oil has a tendency to cling to solids so if you have pads you have oil tied up in it. It may not look like oil is trapped in interface from the surface but if you were to treat these pads and dissolve the acid solubles oil would migrate to top of tank breaking away from interface. Maxflow is second to none when it comes to controlling pads/interface and producing higher skim oil numbers for customers.

What is the satisfactory amount of free oil making it down well bore for disposal well?

Typically industry standard is keeping free oil below 300 ppm. At Maxflow our goal is to keep it below 100 ppm and majority of our results are below 50 ppm. Keeping free oil from being pumped down well is a high priority within this company.

Why is it important to thief tanks regularly?

When a chemical program is started Maxflow expects it’s products to be effective. One of the items promised to customer is controlling pads/interface in water holding vessels. By controlling these pads/interfaces it allows gunbarrel to produce sellable skim oil, prevents oil from clinging to solids and  provide suitable water clarity. The way to gauge your success in controlling pads/interface is to perform tank audits. Pad depth, skim oil, water clarity throughout tank and bottoms are the 4 things we consider, document, and compare to determine the success of our treatment.

What causes well pressure to increase?

Fresh water, scale buildup, solids and tight formations are just some of the reasons well pressure increases. Maxflow provides a chemical program that prevents scale build up in pumps, pipes and perforations, as well as controlling pads/interface. While also providing chemicals preventing solids from migrating into well that has a slick water compound to allow water to flow easier into tight formations. This treatment will maintain and in many cases lower well pressure for higher injection rates.
