Copper Tip Energy Services nitrogen pumping units support coil tubing operations by assisting in under-balanced milling or clean out operations and coiled tubing purging. The units are capable of supplying up to 85 Sm³/min with up to 7,300 Sm³ storage tank capacity providing solutions for a wide range of applications.
Copper Tip Energy Services fluid pumping units carry out but are not limited to Acidizing & Production Enhancement, and Wireline Tool Pump Downs. These units are equipped with dual Triplex Pumps that can carry out a max flow rate of 1.8 m³/min.
Well Servicing Applications
Coil Tubing Support
Virtually all coil tubing operations, including displacing treatment chemicals into the formation, utilize nitrogen. Nitrogen is used to clean out the coiled tubing string following well treatment.
Pumping support for coiled tubing operations including:
- Cleanouts - fluid-based, foam-based, energized fluid–based
- Confirmation Runs
- Reverse circulation
- Well killing
- Pressure testing
- Stimulation – acid spotting
- Cup Frac Movement
Differentially Stuck Drill Pipe
The use of high pressure nitrogen to lower hydrostatic head and allow for freeing of the drill string when the drill pipe becomes differentially stuck against highly permeable formations.
Well Displacements & Injection Testing
Nitrogen can be used for the displacement of wellbore fluids into the formation and injected into the formation to measure permeability and well flow characteristics.
An injectivity test is one of several well tests typically performed on geothermal production and injection wells upon completion of drilling operations. Injectivity tests can be useful indicators of the likely productivity of a well.
Nitrogen is used in assisting snubbing operations in many different ways. Well flow rates are enhanced by adding nitrogen that creates additional energy to assist in the cleanup of unwanted materials, sediments and fluids. Nitrogen is safe on the well bore, so using it through snubbing strings will help retrieve introduced and produced fluids.
Well Treatment: Annular Fluid Level Depression
Gaseous nitrogen can be used to depress annular fluids in order to preserve the casing/tubing from corrosive gases by keeping the casing/tubing in an inert environment.
Acidizing & Production Enhancement
Acidizing treatments can restore and enhance the performance of producing oil and natural gas wellbores. This treatment can also be used to stimulate and improve the performance of disposal wells.
Wireline Tool Pump Down
With the increasing complexity of wells drilled, gravity alone is not adequate for conveying wireline logging tools and perforating guns to target depth. High velocity and high pressure water can be used to carry these tools to the correct depth.
