Even for the most experienced chemists, oilfield chemicals can be complex. Imperative experts simplify product selection and logistics to make it easy to get effective, economical oilfield and pipeline chemicals.
In many types of wet gas and pipeline systems, organic and inorganic deposits, dehydrated alcohols, and chemicals can create situations where compressors and other moving parts need to maintain a higher level of cleanliness. Imperative’s line of antifoulants have been engineered to work in all types of systems across all types of production and transmission.
Oilfield environments favor the growth of anaerobic bacteria, which create many adverse effects in oil and gas systems. These anaerobic bacteria often thrive in oxygen-free systems and, if unchecked, the proliferation of sulfate reducing species can result in numerous well challenges. These challenges include:
Because complete removal of bacterial populations from producing and injection formations is virtually impossible, the most effective approach is to diminish them and limit further growth through proper chemical application. We develop and manage complete custom treatment programs to negate the effects of bacterial contamination in your production system.
In many reservoirs, clay is intermingled within the primary formation lithology. These clays will swell with hydration and close off permeability channels and reduce, or even stop, production. Our line of clay stabilizers are designed to eliminate these interactions and prevent the clays from hydrating and swelling while maintaining your production.
Corrosion costs the oil and gas industry approximately $1.4B annually. There are many factors that increase corrosivity within an oil and gas system—chlorides, gasses that bring acid, and oxidation from temperature and pressure changes, etc. That’s why we’ve developed a range of corrosion inhibitors to protect downhole pipes, pumps, pipelines and surface equipment from the wellhead to the gathering station.
In a normal emulsion, water droplets are suspended in the oil phase of the produced fluids. The stability of an emulsion—or the time required for the oil and water to separate—is often dependent upon the solid, paraffin, asphaltene, and organic acid content of the produced fluids.
We have a diverse line of demulsifiers specifically designed to achieve rapid oil-water separation, and we test each site independently to provide a complete analysis of product compatibility and functionality. Our trained representatives will also survey your production and separation systems, making recommendations to provide optimum treatment rates and application sites.
Enhanced Oil Recovery (EOR) is a process that many oil and gas operators use when the natural drive of the reservoir has depleted. There are many ways to increase production when this occurs, including:
Imperative has the ability to analyze your asset and formulate chemistries specifically designed to meet your needs and improve your oil production.
The addition of foaming surfactants to de-liquefy gas wells can result in excessive liquid carryover and reduce separation of solids and oil from water. These reactions can cause issues like:
While the terms “antifoam” and “defoamer” are often used interchangeably, an antifoam is typically added to prevent foaming, while a defoamer is used to eliminate existing foaming conditions. Our technologically advanced antifoams and defoamers effectively eliminate foaming problems across a broad spectrum of oil and gas industry applications including gas scrubbing, gas-oil separation, drilling muds and asphalt processing.
In order to achieve high rates during a fracturing application or stimulation treatment, friction reducers are added to the fluids to improve water and pipe interaction. With the many types of fracturing designs, fluid systems, and water chemistries that are being used in the oil and gas industry today, proper selection of an FR is Imperative. Our line of FRs are designed to be versatile and compatible with any fluid system being used.
Hydrates are formed when gases, such as methane, are trapped in a crystalline ice structure. These troublesome plugging deposits are found in the presence of gas, water, high pressure, and low temperature. Hydrates can become plugging agents, trapping gas and/or production and causing large pressure spikes in pipelines.
Hydrates can be mitigated with the use of increased heat, dehydration, or chemical inhibition. Once hydrates are formed, however, they must be released by using heat, alcohols (TDHI’s), or salts. If hydrates are a recurring problem, chemicals (TDHI’s/LDHI’s) may be used to stop the nucleation or growth of the crystal structure.
Our line of hydrate chemistries can be tailored to fit your operation’s needs.
Minimization of iron particulates in fluid is essential to maintain flow assurance in acid, fracturing, production, pipeline, refining and water treatment systems. The precipitation of iron minerals and iron corrosion by-products can have adverse effects on all facets of the oil and gas industry:
Imperative provides an extensive and varied line of iron control compounds to ensure cost effective and sustainable solutions to minimize and negate iron related issues, such as:
Iron sulfide presents many challenges in the oil and gas industry. Its presence indicates a problem in the production stream and will cause problems across all aspects of production and transmission. Iron sulfide causes corrosion by bonding to metal surfaces and causing an electrochemical reaction that degrades metal. It can also trap water and other contaminants under its surface causing localized pitting that can be catastrophic. Iron sulfide can also cause flow assurance and plugging issues by restricting flow or closing off formation channels. Iron sulfide can be controlled and remediated through a variety of methods including acid dissolution, oxidation, and chelation.
It is most often formed from:
Imperative has created a proprietary chemistry, WTW-931, to combat iron sulfide. WTW-931 is a versatile chemical that can be used to remove iron sulfide deposits, sludge, and interfaces. Its unique action also can control SRB populations and deodorize fluid and gas streams.
Imperative knows that quick, incremental recovery of oil and gas plays a pivotal role in an operator’s CAPEX budget. The more oil and gas you make, the better and faster you show a return on investment. We have a line of microemulsion and nanochemistry options for your completion needs.
Paraffin is a hydrocarbon compound that often precipitates on production equipment as a result of changing temperatures and pressures within the producing system. It is normally found in the tubing close to the surface of the well, or in the flow lines, but it can also form at the perforations—even in the formation, in depleted reservoirs and in wells that have undergone extensive hot oiling or hot watering treatments.
Asphaltenes, on the other hand, are organic materials that exist as an aromatic agglomerate, stabilized by resin molecules.
Paraffin and asphaltene deposition in production and transmission equipment can result in loss of production due to build-up causing:
Plugged tubulars which will restrict or prevent flow
Blocked perforations and pore spaces
Rod, pump, and valve failures
We design paraffin and asphaltene control chemicals to remove existing deposits in the production system and prevent further precipitation. We offer an extensive line of paraffin control compounds that will allow us to keep your production volumes up. Contact Us if you would like to know more about what our paraffin and asphaltene products can do for you.
When drilling or completing a well, friction is a key factor in the timeliness of meeting deadlines and on the longevity of your equipment. Imperative has an extensive line of pipe on pipe lubricants and liquid beads that are both oil and water based.
When formation waters mix, or are blended with injection water, the incompatibility of ions causes a reaction called “supersaturation”. This leads to scaling, or the deposition of minerals such as carbonates, sulfates, sulfides and chlorites.
As scales form, they hinder fluid flow, reducing production rates and damaging equipment. That’s why scaling becomes such a major flow assurance challenge—one that often requires aggressive chemical treatment, depending on factors such as well composition and the complexity of the scale structure.
Our scale inhibitors work by binding ions that could potentially precipitate as scales. Our products have excellent solubility and thermal stability to combat these mineral deposits by keeping flow rates high and reducing scale formation.
Corrosive gases, such as H2S, CO2, and Oxygen, cause many problems in oilfield systems. Whether causing gas sales issues, exacerbating corrosion rates, or creating inorganic and organic solids precipitation, these gases must sometimes be reduced, or eliminated from the production stream.
Imperative offers an extensive line of scavengers to combat these problems. These chemistries oftentimes need additional compounds to prevent further precipitation of solids or scales because of their molecular reactions with these gases, and Imperative has these covered for you also.
These essential oilfield chemicals lower surface tension of a liquid, the interfacial tension between two liquids, or interfacial tension between a liquid and a solid. The effect of these surface active agents is to enable hydrocarbons to flow more efficiently in a variety of ways. The most common include:
In crude oil midstream transportation, the viscosity of the product plays a major influence in the direct operational expenditures of the company. Imperative carries a line of Drag Reducing chemicals that can help increase throughput while reducing friction.
WTW-931 was developed in 2006 by Imperative. This extremely cost-effective, proprietary chemistry has been used across the United States in all types of completions, production, and water treating. WTW-931 has been utilized to eliminate and control downhole iron sulfide caused by biomass and MIC, FeS interfacial pads, water clarification in SWD’s and produced water reuse, and low level H2S scavenging.
