Well servicing pumps are frequently used in workover operations, which involve interventions aimed at restoring or enhancing the production of an oil or gas well. These operations may include tasks such as removing debris from the wellbore, replacing pumps or equipment, and re-establishing flow after problems like scale buildup or equipment failure.
In acidizing operations, well servicing pumps are utilized to inject acid, usually hydrochloric acid, into the well. This process is designed to dissolve limestone, dolomite, or other formations that have become blocked by scale or other deposits. Acidizing is crucial for enhancing the flow of hydrocarbons from the reservoir to the surface.
Well servicing pumps are employed in Hydraulic Fracturing (or "fracking"), where fluids are injected at high pressure to fracture the rock formations and increase the permeability of the reservoir. This process helps to stimulate the flow of oil or gas from tight formations.
Cementing is a critical process in well construction and maintenance. Well Servicing pumps are used to inject cement slurry into the wellbore, filling the annular space between the casing and the wellbore to provide structural integrity, prevent fluid migration, and isolate different zones in the reservoir.
Well servicing pumps are used during Well-Killing operations, where heavy fluids are pumped into a well to control or stop uncontrolled production or blowouts. This is done by adding heavy fluids like kill mud to the wellbore to increase pressure and stop the flow of hydrocarbons.
In many well servicing applications, pumps are used to Circulate Drilling fluids (also called mud) during operations like well cleaning, pressure testing, and well completion. These fluids are used to cool the bit, remove cuttings, and control pressure during drilling or servicing operations.
Well servicing pumps are used to Pressure Test the wellbore, casing, or other equipment to verify its integrity and ensure there are no leaks. This process is essential in maintaining the safety of operations and ensuring equipment is functioning as intended.
Well servicing pumps are used in cleaning operations to remove sand, debris, or other unwanted materials from the wellbore. They can also be used in sand control operations to inject chemicals or materials that prevent sand production from the reservoir.
During a well shut-in or workover operation, well servicing pumps circulate fluids to maintain wellbore stability, pressure, and integrity during the downtime.
In gas lift operations, well servicing pumps can be used to inject gas into the production tubing to lift liquid hydrocarbons to the surface. This is done to assist in artificial lifting when the natural reservoir pressure is insufficient.
After hydraulic fracturing, well servicing pumps are used during the flowback process, where fluids (including fracturing fluids and any other injected materials) are pumped back to the surface. This is essential for clearing the wellbore and preparing it for continued production.
