What are Downhole Applications in Well Intervention?

Well Intervention Downhole applications, which take place inside the wellbore to address production-related problems, can be divided into groups based on the work procedures they employ or the tools and equipment needed to carry them out.


The following are the top 10 primary rigless well intervention application categories:

·      Production of cased holes To diagnose the reservoir, produce from new zones, or unblock clogged holes, logging and perforating are undertaken.


·      Cleaning a well entails removing formation fills and scale that are wellbore flow obstructions.


·      By removing downhole equipment like packers, liners, or screen pipe, cased hole fishing restores a productive well. It also involves unsticking wireline equipment.


·      Circulating a fluid, such as nitrogen, through the well to start production or enhance the reservoir's transport and flow qualities


·      Through-tubing sand control is a process that uses filter media, screens or liners, or resin materials to stop sand from depositing in the production stream.


·      Cement slurry is forced to a certain location in a well for remedial reasons in the process of "remedial cementing" or "conformance." Due to its application in sealing off zones to turn off gas or water, it is frequently referred to as compliance control.


·      By utilising high injection rates and pressures to fracture the reservoir with fluids, stimulation increases permeability close to the well zone.


·      Through-tubing completions use a small diameter tubing to serve as a production string to isolate broken or defective production tubing or as a velocity or syphon string to keep marginal wells empty. Additionally, a gas lift injection string can be made from it.


·      Services for artificial lift help increase output in low pressure wells by setting up artificial lift methods or equipment.


·      Re-entry drilling increases production by drilling horizontal laterals to access more pay zones or by drilling deeper wells.


Because it relies on the reservoir's properties, the region, and the economy, it is challenging to anticipate how often Well Intervention will need to be intervened in order to carry out the different downhole operations. To fully resolve the well issue, one standalone application or numerous applications may be necessary.
