... of fractures, hereby, planned stimulation measures were cancelled in spite of low injectivity. In addition, falloff tests give additional information on how waterflooding is effectively carried out. Another case which was under active discussion includes the issue of converting a well to water injection, so we...

Paper Number: SPE-198365-MS
... for effective acid stimulation because of poor acid distribution over the long interval. The Mishrif formation in the Minagish field in west Kuwait is a challenging tight carbonate with poor reservoir quality, relatively low pressure, and no external pressure support. The stimulation methodology was highly...

... and support in the Caspian Sea. As previously acid stimulation is infrequent and on individual wells only, the cumulative impact to topside facilities during multiple flowback operations of corrosive acid had not been accessed and understood. This was important as corrosive chemicals can potentially...
