... high-injection rates into the formation. Field data shows that injectivity and productivity increased after treatment. In some cases, the downhole pressure decreased for the injectors. Cleanup and removal of the NADF from the Gulf of Guinea wells was beyond the capabilities of conventional treatments...

... is applied to cake equilibrium criterion and the lever-arm ratio is calculated using Hertz's theory for contact deformation of cake and particles. An implicit formula for the cake thickness along the well is derived. Two regimes of the stabilized cake build-up correspond to low and high injection rates...

For each set the first two cores were treated by 5 wt% HCl regular acids at injection rate of 2.5 cm 3 /min for Cores# A1 and B1 while at injection rate of 20 cm 3 /min for Cores# A2 and B2. Regular acid was injected until acid breakthrough was achieved. Gelled...
