formation damage

[fȯr′mā·shən ‚dam·ij]

Since the 1960s, experts had noticed that formation damage is caused by clay mineral (Hewitt, 1963).
By using Aphron drilling fluids, lost circulation to formation will be minimized and by providing a flexible seal on formation openings and micro fractures, formation damage will be neglected.

Pryme's wholly owned US subsidiary, Pryme Energy LLC ("Pryme Energy"), as operator of the Rosewood Plantation 21H well located in Avoyelles Parish, Louisiana, has initiated legal action against Signa Engineering Corporation ("Signa") to recover losses in connection with the formation damage and certain costs overruns.
Oil well stimulation by acidising methods involves pumping a variety of acids, including hydrochloric acid, sulphuric acid, and acetic acid, through tubular goods into an oil reservoir to remove formation damage and increase porosity in the formation.
With the help of hydraulic fracturing, the formation damage can be uprooted effectively and high permeability channels are created which offer lesser pressure drop even compared to original reservoir permeability channels for the same production rate.
