Oil & Gas Well Servicing
OEI is the proud leader in offering unique, customer-centric filtration solutions to well-servicing equipment manufacturers and end users. OEI continuously innovates to provide highly-effective cleanable filtration for systems that can not accommodate conventional filters due to either flow or space restrictions. OEI has proven success protecting high-pressure pumps,compressors and injectors as well as standard systems such as hydraulics, reservoirs, lube oils and fuels.

NEW-BUILD N2 PUMPER
APPLICATION / FLUID
STEP Energy Services (STEP) and National Oilwell Varco are reliability leaders in the oil and gas downstream industry. STEP and NOV have partnered with OEI on mulitple occasions to design and manufacture well servicing equipment that is outfit with state-of-the-art magnetic filtration solutions with the intent to drive reliability, safety, and cost savings.
STEP Energy Services holds themselves to their own high expectations for exceptional client services; through accountability, technical knowledge, purpose-built equipment, and industry leading proactive maintenance programs. The team at National Oilwell Varco pride themselves on harnessing experience and innovation to minimize risk, increase uptime, and improve performance for drilling operations around the world.
As part of their proactive maintenance program, STEP Energy Services deploys OEI magnetic filtration on all major equipment components to protect fluids, gases, and lube oils against sub-micron wear contamination. To ensure the highest-quality builds, National Oilwell Varco collaborates with OEI to design filters that meet their new-build equipment installations, space restrictions, and fluid application parameters.
In 2018, NOV, STEP and OEI collaborated to outfit a new-build N2 Pumper with 13 uniquely designed OEI magnetic filters. To showcase the criticality of employing OEI filtration on new-build equipment, a test was run to determine how much break-in wear contamination is produced during initial operation. Without immediate protection, as soon as equipment enters service, break-in wear contamination down to 4 microns and below would damage critical equipment components and reduce operating life.
Run the new-build N2 Pumper for 5 minutes with 13 magnetic filters deployed on the various fluid applications. Evaluate how much break-in wear is produced to determine the criticality of magnetic filtration at the OEM level.
After the first 5 minutes of runtime, every magnetic filter installed pulled significant amounts of wear contamination from the system. Without magnetic filtration, the contamination would continue to circulate through critical systems, wearing on components and causing premature failures. If left in the system, the break-in wear contamination would build throughout the N2 Pumper, damaging close tolerance components such as bearings, injectors, and valves.

Trencher Hydraulic Fluid Reservoir Kidney Loop Filtration
Wajax was hired as the hydraulic design and service team for a new-build trencher. The initial hydraulic filter and flushing methods were not effective in removing break-in wear contamination. After initial operation, the ferrous particles left in the system caused catastrophic hydraulic pump and seal failure. Wajax was tasked with replacing the pumps and cleaning the system before the next start up.
Ocean Edge Services Subsea HPU Hydraulic Fluid
Inadequate filtration was allowing wear contamination under 4 microns to degrade the water-based-glycol hydraulic fluid that is used to operate Ocean Edge’s subsea HPU. This contamination damages the DC valves which have tolerances below 1 micron. In these systems, if any contamination is present, the effects can cost millions of dollars to resurface the HPU for repairs.
A cleanliness level of 6 NAS is the standard for subsea control systems. When conducting fluid treatment, traditional filtration takes 10 to 12 hours to achieve a NAS 6 and that still leaves the system vulnerable to valve failure.
Nabors Drilling HPU Hyrdaulic Fluid
The tolerances of hydraulic systems are 4 micron to sub-micron, and traditional filtration is unable to remove this contamination to these levels.
Once a month, a large filter truck is hired to filter the hydraulic fluid from the HPU for a 16 hour interval. This filtration is costly and unable to remove wear particles under 4 microns that cause hydraulic valve failures.
Basic Energy Coil Tubing Unit’s Bi-directional Hydraulic Line
The cartridge valves on the bi-directional hydraulic line of a coil tubing unit have very tight tolerances; the conventional filters were not removing contamination that was causing valve failure every 6-12 hours. After 5 weeks of failures, BASIC Energy decided to test OEI’s magnetic filtration capability. The objective was to sufficiently clean the hydraulic fluid and extend the life of the valves to the standard 8-12 months.
Orion HPU Kidney Loop Filtration
The challenge was to capture wear contamination down to sub-micron levels to prevent another cylinder failure caused by wear contamination in the hydraulic fluid.
New-Build N2 Pumper Break-in Wear Test
In 2018, NOV, STEP and OEI collaborated to outfit a new-build N2 Pumper with 13 uniquely designed OEI magnetic filters. To showcase the criticality of employing OEI filtration on new-build equipment, a test was run to determine how much break-in wear contamination is produced during initial operation.
New-Build N2 Pumper Nitrogen Filtration
The challenge was to protect the seals and nitrogen pump from the break-in and inherent wear contamination. High levels of ferrous contamination in the nitrogen cause damage to the cold ends and wear the seals of the nitrogen pump on start up. Traditionally, these systems do not have any filtration allowing for wear particles to move freely throughout the system, damaging components.
Canyon Technical Quintuplex Pump Protection
On cold start up, the traditional filter goes into bypass allowing the inherent contamination to flow through the system causing premature pump, bearing and conrod failure. This results in costly hose and cooler clean up. The most damaging contamination is below 4 microns because it wears on close-tolerance components such as bearings.
Tesco Top Drive Diesel Fuel Filtration
Contaminated diesel fuel in Tesco’s Top Drive Rental Unit was causing premature wear of the fuel system components, reducing burn efficiency and increasing emissions. The source of this contamination is the corrosion and erosion of the transmission lines carrying the diesel fuel to the end user.
Pioneer 3512 CAT Engine Oil
The challenge was to clean new engine lube oil on a 3512C CAT engine to a level that exceeds the ISO fluid cleanliness standard 18/16/13, and to extend engine component life so that maintenance intervals could extend to align with quarterly inspections.
STEP Energy Services Coil Tubing Unit Coolant
An older coil tubing unit had a dirty coolant circulation system running 75 gpm at 150 psi, that required remediation. Over the course of 7 years, this coil tubing unit’s glycol pump failed
three times. The challenge was to increase filtration capability and guarantee pump protection
Weatherford Colombia Diesel Fuel Dispenser
Weatherford Colombia was finding high levels of ferrous contamination in their diesel fuel. Equipment running on the dirty fuel required sub-micron level filtration; without it, the equipment was experiencing premature wear of fuel system components, reduced burn efficiency and increased emissions.
Precision Drilling Top Drive Closed Loop Hydraulics
As this is a closed loop system flowing 300 gpm from their pump to the motor and vice versa, Precision Drilling needed a filter that was capable of filtering bidirectionally. The conventional filters in place between the pump and motor was unable to protect against particulate under 10 microns. The tolerances of the pump and motor components are < 4 microns. Further, they required filtration for the fluid before the pump to protect against contamination produced by the motor.
Pioneer Natural Resources Frac Truck Bumper to Bumper Filtration
The critical system components on Pioneer Natural Resources’ new build frac pumper have tolerances under 4 microns. Traditional depth-media filtration is unable to effectively filter contamination under 10 microns in size. To prevent unsccheduled downtime and maintenance, Dan Stoye, Maintenance Manager for PNR, decided to outfit the frac pumper with OEI magnetic filtration.
OEI magnetic filters are designed for 95+% efficiency: they are optimized for fluid viscosity, flow volume, flow rate, temperature, mobility, and mounting requirements.
