Sprint has long standing experiences in Nitrogen services and operations covering thousands of oil well kick offs, Nitrified fluids pumping, foamed acid aplications, foam cementing jobs, leak detection and pressure testing for pipelines, gels and foam pigging for pipelines, gathering centers and processing plants purging, etc.
Nitrogen Pumping Equipment
Sprint’s Nitrogen Pumper fleet consists of units with pumping capacities in the 90K-180K scf/min range and pumping pressures capabilities of up to 10,000 psi.
Nitrogen Pumpers are equipped with diesel engines, vaporizers and cryogenic triplex pumps. A variety of fluid-end sizes are available to suit the required pressure and flow rates for each operation.
Units are available on a skid/trailer or on a body load truck which carries a 2,000 or 4,000 gallons (7570 or 15142 litres) nitrogen tank.
Nitrogen Pumping Services
Sprint Oil & Gas Services provides Nitrogen pumping services for several well applications including:
- Nitrogen Lifting
- Energizing Fluids
- Foam Diversion
- Foam Cementing
- Plant & Pipeline Purging
Nitrogen lifting is commonly used to enable a well to flow initially or bring a previously flowing well back into production. Nitrogen is used as a means of unloading and under balancing the well to a point where the well flows naturally and driven by its own reservoir pressure.
Through a simple calculation, with the known reservoir pressure and weight of the completion fluid in the well, the amount of overbalance can be calculated and the respective minimum depth of lift pinpointed.
Sprint TAS, Cempro and Stimpro simulators are used to simulate these calculations. Situations requiring more complex calculations, such as in case of underbalance perforation or foam cementing, can also be quickly and efficiently made using these simulators.
Energizing fluids is a technique that allows the pumping of different fluids and acid systems into a well while maintaining the overall hydrostatic pressure of the fluid column in the well bore below reservoir flowing pressure. This enables the well to flow back immediately after the completion of the job without the need to lift the well with coiled tubing and Nitrogen.
Energized acid fluids such as Sprint foamed SRA Silt and particle Removal system or foamed DPGA Deep Penetrating Gelled Acid can also help deeper acid penetration and delay its reaction rate.
Foamed base fluids using Nitrogen gas and foaming agents is a well-known technique to create downhole foam pads for diversion purposes. The foam diverter is pumped in staged slugs between main acid stages to divert acid into tighter/non treated zones.
Sprint foam diversion service helps improve treatment diversion across the entire pay zone, thus, improving the well stimulation yield while minimizing formation damage when compared to conventional particle diverting pills.
Foam cementing is a well-known technique used to design a light weight slurry with densities lower than water, but with outstanding mechanical and dynamic properties. Beside helping for improved slurry placement under low reservoir pressure conditions, it provides set cement with outstanding mechanical properties such as compressive strength and permeability.
Sprint foam cement uses industry leading surfactant and slurry stabilizers to develop a stable and ultra-light weight cement slurry.
Nitrogen Plant and Pipeline Purging
Nitrogen gas is highly effective for pipeline purging, pipelines displacement, plants dehydration purposes and corrosion protection.
Sprint designs specific custom procedures for the displacement of unwanted gases by Nitrogen purging. This includes the removal of hydrocarbons, Oxygen, or other toxic or reactive gases. Our engineers are equipped with industry-standard software systems to determine the optimum rate, temperature, and volume required to remove unwanted products in the safest and most efficient way.
As Nitrogen is inert, it doen not support combustion. Therefore, once a system is purged using Nitrogen, there is no risk of ignition within that system. Nitrogen will also help preserve plants and pipelines and reduce corrosion caused by oxidation making it ideal for protection for prolonged periods of no use.
This service also includes:
- Plants and pipelines decruding to remove residue oil using Nitrogen
- Plants and pipelines dewatering and drying: displacing water or moisture with Nitrogen after testing. This procedure also includes heating up the Nitrogen to remove any residual moisture from the system
- Nitrogen purging, cutting and welding: displacing Oxygen in plants and pipelines with Nitrogen to prevent corrosion and to safely allow cutting and welding operations
- Nitrogen degassing: displacing corrosive gases, such as H2S and CO2, in plants and pipelines
- Cooling down piping and vessels system in plants when they exceed safe operational temperatures
- Pressure testing and leaks detection: Nitrogen is a more time effective solution for finding leaks in gas lines, vessels, plants and pipelines system before they are returned to service. Pressure testing with Nitrogen can usually be completed in half the time as compared to hydro testing
