Abstract:

In this research work, well stimulation to increase oil production was carried out. Squeeze/soaking of the reservoir was done using de-waxing solvent over-night and the acid washing of the perforation face/ soaking for 30 mins. Nitrogen was deployed to kick off the well immediately. Acidization of the reservoir was carried out using 15bbls of 10% HCl + 2.5gal 1-17A + 7gals versine -100 + 4 gals Dow-fax and 63gals WSA. Before the stimulation was performed, the CITHP and the FTHP of the well was relative low at a value of 35psi and 105 which was not producing (no flow). The no production was because of wax/ paraffin deposit across gravel-pack and perforation. In order to restore production and enhance productivity, the well was effectively stimulated using matrix acidizing method and the result from the post stimulation analysis showed an average production rate of 1628b/d. The evaluation of the stimulation treatment reveals a remarkable success.
