Abstract
Penetrating a reservoir is an important part of well construction. Non-quality penetration may cause clogging of the reservoir’s pore space, which in turn may lead to a low hydrocarbon debit or its absence. Searching for a solution to this problem is costly and complicated, and may eventually turn unsuccessful, leading to loss of time and money. The authors have examined the existing types of flushing fluids used in penetrating the reservoirs. The advantages and disadvantages of the fluids, as well as the degree of their influence on the reservoir rocks have been defined. Based on the data obtained, the authors have proposed a method for minimizing the negative impact of the flushing fluids on the reservoir. The method allows reducing the depth of the flushing fluid filtrate penetration in the reservoir, which increases the deliverability and life of the well.
