The problems arising when drilling horizontal and gently sloping wells in the Valanginian deposits are considered. The analysis of technologies of drilling-in the Valanginian reservoirs by sideholes using water-base clay drilling muds and the aerated muds ensuring the high-quality exposure of productive layers is carried out. The most perspective for drilling side holes of wells in these conditions are hydrocarbon-base drilling muds which maintain the filtration properties of productive layers and reduce the accident rate of drilling operations.
