With rising energy demands, the need to be more considerate of the environment, and volatile prices, it’s crucial every step of the process is efficient. The average platform runs at only [77% of the maximum production potential](https://www.mckinsey.com/industries/oil-and-gas/our-insights/why-oil-and-gas-companies-must-act-on-analytics), leaving a big gap to recover. This shortfall comes at a price – a day’s downtime for a company producing 220,000 barrels per day would cost 25 million USD in lost revenue. And on average, producers experience 27 days of downtime every year. #### 27 days of downtime = $675m in lost revenue That leaves plenty of opportunities to improve the production process. *Based on current prices and 220,000 daily barrels   ![Docked ship at an offshore oil rig](https://www.amazonfilters.com/hs-fs/hubfs/Aerial%20Rig.jpeg?width=3000&height=800&name=Aerial%20Rig.jpeg) ## The role of water in oil production Water processing is pivotal to the upstream process. It’s injected to enhance oil recovery and produced as a by-product of extraction. Energy producers generally use and filter two types of water. **Produced water: **water that comes out of the well with the crude oil during crude oil production. Produced water contains soluble and non-soluble oil and organics, suspended solids, dissolved solids, and various chemicals used in the production process. **Seawater: **a complex mixture of water, salt, chemical compounds, and dissolved oxygen. Seawater has a lot of organic matter in it, including algae and bacteria. > **Energy producers pump more water than oil every day, so improving the water treatment process will impact oil production levels.**   ### Why do energy producers need to get water treatment right? Water treatment is vital for protecting [downstream ](https://www.amazonfilters.com/industry/downstream-processing-filtration)membranes, pumps, and other processing equipment. It prevents blockages in the well formation and is a crucial part of adhering to changing legislation around extraction. Having an optimised filtration system increases runtime and reduces money lost on [filter cartridge](https://www.amazonfilters.com/products/filter-cartridges-and-capsules) replacements, equipment maintenance, and downtime. This can deliver an OPEX benefit that cancels out CAPEX expenditure within the first year of operation. As facilities can operate for more than 25 years, it’s well worth the investment. ![Close up of green seawater](https://www.amazonfilters.com/hubfs/Green%20Water.jpeg) ## Water treatment techniques and applications ![selecting-the-right-materials-icon-1](https://www.amazonfilters.com/hubfs/selecting-the-right-materials-icon-1.svg) ### Seawater Injection Water needs filtering before injection to prevent the well from getting damaged or blocked. The level of filtration required depends on the formation water is being injected into. Where sulphate reduction is required, [membrane protection](https://www.amazonfilters.com/blog/when-to-replace-a-membrane-filter) is critical. Protecting membranes with filters maximises plant uptime and increases the volume of injection water produced so more oil can be extracted. ![food-and-beverage-icon](https://www.amazonfilters.com/hubfs/food-and-beverage-icon.svg) ### Produced Water Produced water is filtered to remove residual oil before it’s injected or disposed of. With increasingly stringent environmental regulations limiting overboard disposal, reinjection is common both as a more environmentally friendly solution and as a useful source of water for enhanced oil recovery. Effective filtration is critical as a final processing stage to protect the rock formation, and to protect [coalescing filters](https://www.amazonfilters.com/products/filter-cartridges-and-capsules/coalescers) as they remove residual oil from the water. ![product-purity-icon-1](https://www.amazonfilters.com/hubfs/product-purity-icon-1.svg) ### Drinking water To operate offshore, employees need a constant supply of drinking water. Producers supply this via tanker or by purifying seawater through a reverse osmosis plant. Where reverse osmosis systems are used, effective [pre-filtration](https://www.amazonfilters.com/case-study/fast-track-replacement-prefiltration-system) is vital to ensure enough drinking water is produced and to avoid frequent and expensive membrane replacements. #### Key water treatment challenges **Seawater/drinking water **– biological materials such as bacteria and algae **Produced water **– waxy crudes, chemicals to help the upstream process, coagulation ![Rig worker in an orange high-vis jacket and white hard hat, reviewing the facility's water treatment equipment](https://www.amazonfilters.com/hs-fs/hubfs/ImproveProcess.jpeg?width=3000&height=800&name=ImproveProcess.jpeg) ## 5 ways to improve your water treatment process ### Follow these tips and you'll... ![Stopwatch Icon](https://www.amazonfilters.com/hubfs/Stopwatch%20Icon.svg) ### Suffer less downtime ![Existing Icon](https://www.amazonfilters.com/hubfs/Existing%20Icon.svg) ### Change filters less often ![product-purity-icon-1](https://www.amazonfilters.com/hubfs/product-purity-icon-1.svg) ### Improve filtrate quality ![icon_Server](https://www.amazonfilters.com/hubfs/icon_Server.svg) ### Save on unnecessary OPEX ### 1. Focus on cost vs. benefit Budgets and CAPEX are important to protect. But that doesn’t mean the cheapest filtration solution is the best one for the job, will be cheaper overall, or will deliver the lowest carbon footprint. It’s worth taking time to research and understand what’s going to give you a better ROI. Some filters are cheap but have a short life – that means more changeouts, downtime, and replacements. We helped one [multi-national oil and gas producer](https://www.amazonfilters.com/improving-the-economics-of-produced-water-filtration) achieve a 30-fold decrease in filter cartirdge use by adopting a bespoke filter media based on our [SupaPleat II](https://www.amazonfilters.com/products/filter-cartridges-and-capsules/pleated-filters/supapleat-ii) product. Not only did this deliver huge cost savings, it also had a significant impact on the amount of waste going to landfill. ### 2. Choose the right filter As contaminants in water, extraction legislation, and filtration specifications are so changeable, using optimal filter technology is crucial. If the filtration solution isn’t right and you don’t consider the whole process, including [upstream](https://www.amazonfilters.com/industry/upstream-processing-filtration) and downstream equipment, then production performance can severely suffer. > **In some cases, energy producers end up with poor quality filters that don’t deliver the efficiency they promise. This can result in 50% less operating capacity.** For [seawater filtration](https://www.amazonfilters.com/blog/optimise-on-shore-off-shore-seawater-filtration), look for filters with anti-algal or antibacterial coatings to combat [biofouling](https://www.amazonfilters.com/application-notes/prevention-of-biofouling). This helps the filter last longer so you have fewer changeouts, saving time and money. It can also help to protect reverse osmosis membranes meaning they need cleaning and replacing less often. Using the right filter also helps to protect operational equipment and rock formations while recovering oil reserves. If you don't filter injection water properly, contaminants can block the pores of the rock formation. This will reduce the flow rate of injection water or block the well entirely, meaning little to no water can get in to extract the oil. ### 3. Don’t underestimate housing design Poorly designed and sized [filter housings](https://www.amazonfilters.com/products/filter-housings) can lead to high year-on-year operating costs and impact production levels. Unsuitable internal supports can cause filters to operate at high differential pressures when they’re clean. This leads to higher energy and pumping costs and limits the differential pressure available for cartridge fouling. Other issues like flow impingement or unseating of cartridges can compromise filter integrity and reduce efficiency. Access closures can make the cartridge change-out process inefficient. You’ll need more people and, in some cases, cranes. This can take 20+ times longer than a well-designed access closure. These all have a negative impact on production and OPEX. A good supplier will offer [bespoke housing design](https://www.amazonfilters.com/products/customised-filter-housing-and-skids) or consultation to ensure you have the right combination for your job.   ![Water treatment equipment at an gas production facility](https://www.amazonfilters.com/hs-fs/hubfs/Pipes.jpeg?width=3000&name=Pipes.jpeg) ### 4. Get help from your specialists Work with a supplier who’ll collaborate well with your process and mechanical engineers. They can recommend the most appropriate technology, micron rating, and cartridge construction based on: - Particle loading and size distribution - Other contaminants present - Equipment used upstream and downstream ### 5. Choose the right filter partner Suppliers don’t always understand the oil production process enough to offer the best solutions, but it’s crucial they do. This is especially true when downtime comes at such a high price. A lack of knowledge of the entire process can cause: - Filters to be sized based on flow rate only, rather than taking the whole process and application into consideration - An imbalance of CAPEX and OPEX - Upstream pre-filtration equipment not to be considered in the solution - A solution that’s not durable enough to withstand challenging operating conditions and will not last for as long as the plant is operational - You to have no expert advice available if something goes wrong during commissioning or production ![Two oil rig workers in yellow high-vis jackets and white hard hats talking to a filtration supplier](https://www.amazonfilters.com/hs-fs/hubfs/Suppliers.jpeg?width=3000&height=800&name=Suppliers.jpeg) ## Getting the best from your supplier Not all suppliers are created equal. Service continuity and levels vary, and product quality differs too. Here are some traits to look for to get the most from your investment. ![icon_Settings](https://www.amazonfilters.com/hubfs/icon_Settings.svg) ### Product and industry expertise A good supplier will design, manufacture, and install filters for you. They’ll also know your industry and processes inside out so they can recommend you the most suitable products. ![icon_Communication](https://www.amazonfilters.com/hubfs/icon_Communication.svg) ### Accessible team Look for problem-solvers with a proactive culture who want to communicate and work with you to offer the best solutions. ![icon_Repeat](https://www.amazonfilters.com/hubfs/icon_Repeat.svg) ### Quick, agile, and customisable service Choose a supplier who can be flexible with your demands and provide a quick turnaround. A supplier who can customise their products to suit your needs is even better. ![icon_List](https://www.amazonfilters.com/hubfs/icon_List.svg) ### Focused on performance The best suppliers focus on improving their products. For example, maximising effectiveness and minimising your filtration spending. ![icon_Check](https://www.amazonfilters.com/hubfs/icon_Check.svg) ### Proven and trusted They should have lots of experience with customers of all sizes, markets, and locations. Complying with regulations shouldn’t be a problem for them. ![Close up of green waste water with a thick film of scum](https://www.amazonfilters.com/hs-fs/hubfs/PlantMembraneProtection.jpeg?width=3000&height=800&name=PlantMembraneProtection.jpeg) ## Case study ## Improving process economics for sulphate reduction plant (SRP) membrane protection ### The challenge The service life of a prefilter in the [sulphate reduction process](https://www.amazonfilters.com/application-notes/supaspun-kilbac) is directly related to inlet water conditions. These conditions can vary by location, season, and weather. Biological contaminants such as algae reduce filter lifetime and increase downtime and cost. ### The solution To combat the build-up of biological contaminants, we developed and launched a filter range called [KilBac®](https://www.amazonfilters.com/products/filter-cartridges-and-capsules/depth-filters/supaspun-kilbac). KilBac uses micron-sized particles containing active silver, zinc, and copper to combat the growth of bacteria and algae. This extends cartridge life and improves performance. Due to the rapidly changing conditions of inlet seawater, it’s difficult to trial filters in a standard test environment. So, we partnered with a global energy producer and launched a rigorous test programme. We tested three different filters in parallel with the same quality seawater and biological exposure. - 5-micron anti-algal SupaSpun KilBac® - 5-micron antibacterial SupaSpun KilBac® - 5-micron untreated standard SupaSpun II filter ![Pouring Water](https://www.amazonfilters.com/hs-fs/hubfs/Pouring%20Water.jpeg?width=2000&name=Pouring%20Water.jpeg) ### The results Our testing showed that KilBac® technology can significantly improve the seawater filtration process. Compared to the untreated standard SupaSpun II: - The KilBac filters exhibited half the differential pressure - The anti-algal SupaSpun KilBac had a 39% higher dirt holding capacity - The antibacterial SupaSpun KilBac had a 125% higher dirt holding capacity Having KilBac technology on filters: - Can double the service life of a cartridge, reducing annual filter costs along with the carbon footprint reduction from lower logistics costs, fewer man hours required for maintenance, and reduction in the amount of waste to be disposed of - Offers greater protection of the downstream membranes, reducing downtime and the expense of cleaning and regenerating - Reduces frequency of change-outs, minimising downtime - Keeps filters operational under increased levels of organic contaminants from unexpected occurrences, e.g., localised algae blooms ![Shot of the ocean just below the surface, with numerous bubbles of different shapes and sizes rising to the top](https://www.amazonfilters.com/hs-fs/hubfs/Underwater.jpeg?width=3000&height=800&name=Underwater.jpeg) ## Save time and money with Amazon Filters **Optimising your water treatment process is critical to reducing downtime and increasing revenue.** We can assess your existing [water filtration systems](https://www.amazonfilters.com/industry/water-filtration) and offer expert advice and manufacturing to improve your process. ## Why us?
