... to previously untested development methods and methods of enhanced oil recovery in ultra-low-permeability reservoirs of the Achimov deposits. The analysis and the results of partially conducted pilot projects (at the moment) have showed a high potential for gas injection in certain areas of the field...

... Abstract The gradual depletion of conventional oil reserves and the growing demand for hydrocarbon feedstock have led to shale deposits development necessity, which are characterized by high reservoir temperatures and very low permeabilites. One of the methods proposed for unconventional...

... and the necessary parameters for this method to achieve an economic energy to oil ratio. An iterative process is followed to couple the heat rate generated by electromagnetic induction heating to the reservoir model over a defined period. The reservoir model represents a 33 meter payzone with properties...

We present the results of pilot work to determine the inflow profile in a horizontal well based on DNA markers. The technology is based...

...-injection, are becoming relevant. The re-injection options include: injection into underground reservoir for storage (if there are reservoirs suitable for injection near the field), injection into a gas cap, if any, or injection into a productive reservoir. The latter method allows, along with solving...

... – Lower zones are Callovian and Bathonian-Bajocian reservoirs of the Middle Jurassic. The reservoir rock is made of sandstones, siltstones and shale. The reservoir pressure gradient is up to 2.19 g/cm 3 , the reservoir temperature is up to 168 deg C. The reservoir can be saturated with oil...

...The existing approach to interpretation of RTA data RTA is a set of methods of the field data analysis on operating wells. The purpose of the data interpretation for the well rate and bottomhole pressure is determining of the layer and reservoir characteristics, forecasting of further oil...

The main feature of the pressure analysis was the short period of production. With such well completion geometry and reservoir properties of the layer, the radial flow...

... Field data analysis for XXIV-2 sector was split in 3 parts: reservoir pressure analysis, production data and Voidage Replacement Ratio (VRR) analysis. The analysis was complicated by a temporary increase of injection in one of the neighboring down-dip injectors – WI-4 ( Figure 2 ). WI-4 injection...

... Abstract In the presented paper, the object of the study are carbonate rocks of the Riphean and clastic-carbonate rocks of Vendian-Cambrian ages, uncovered by the well drilled at Yurubcheno-Tokhomskoye field. These reservoirs are characterized by extremely low porosity (1-4%) and determining...
