The effect of particle size distribution and the nano-sized additives on the quality of annulus isolation in well cementing

The paper presents the comparative study of portland cement compressive strength dependence on nano-TiO2 and nano-SiO2 addition, as well as various fine modifications. It was shown the impact of nano-additives concentration, the specific surface area of the cement powder and particle size distribution on compressive strength changes while 1, 2, 7 and 28 day’s period. The addition of nano-SiO2 and nano-TiO2 led to the increase of compressive strength at early stages of hardening by 35.71% and 37.14% respectively and 18% and 20% at a late stage. Compressive strength of the most finely dispersed cement sample (R-6) was higher by 112%, and 42% at early and later stages of hardening, respectively in compare with ordinary cement powder (P-1). To predict the strength of cement at different stages of hardening was obtained multiple regression equation with a high determination coefficient for early and late stage strength R2 = 0.92 and R2 = 0.95, respectively.

Keywords: Portland cement; Specific surface area; Compressive strength; Nano-SiO2; Nano-TiO2; Multiple regression equation.

Optimization of offshore hydrocarbon field development and construction project

The article pointed out that the optimization technique for offshore hydrocarbon field development and construction project allows us to minimize the number of capitalintensive and labor-intensive fixed offshore platforms (FOP), providing the optimal number of FOPs or the optimum ratios of FOPs and subsea production complexes (SPC), placing at that the SPC at such a distance from FOP when there is provided optimum number of wells by options, which are drilled from these platforms, as well as the length of manifolds from SPC to FOPs, and as a result general optimization of the hydrocarbon fields development and construction project. The proposed in the article problem-solving approach will enable to adapt it with little difficulty to gas and gas condensate fields.

The variance of physical properties of petroleum and the controlling factors in fula depression, Muglad basin, Sudan

The main oil-bearing layers in Fula depression of Muglad Basin in Sudan include the Abu Gabra (AG) formation, the Bentiu formation, the Aradeiba formation, the Zarqa formation and the Ghazal formation. The organic material and geochemical characteristics of their source rock are similar in each oilfield, but the API gravity and viscosity of the petroleum from different layers in different oilfields are different to some extent. Multiple data are comprehensively employed to analyze the change in the physical properties of the petroleum and the controlling factors. The results show that the mechanism of the physical property change is petroleum degradation which mainly includes biodegradation, then the effects of water washing and oxidation are relatively weak. The controlling factors of petroleum degradation are block intensity of meteoric water infusion and sedimentary facies. The more severely the petroleum is degraded, the lower API gravity and higher viscosity it is.

Keywords: Alteration of petroleum physical properties; Petroleum biodegradation; Block intensity of meteoric water infusion; Sedimentary facies.

Analytical equations of state of natural gas and their role in mathematical modeling

The analysis of equations of real gas state by comparison with reliable experimental data in a wide range of pressure and temperature has been performed. Testing includes the coefficient of compressibility, throttling factor, as well as «an inverse curve» and normalized to gas constant the difference between specific isobaric and isochoric heat capacities. It has been shown that the best results are obtained with  the Redlich-Kwong equation

The effect of dynamic permeability the decrease of the drained gas reserves cenomanian deposits

The analysis of the background of massive gas storages development shows that one of the main problems of creating a geological and technological model is adaptation of formational pressure dynamics, while decreasing drainage volume of gas reserves. The articles demonstrates that low values of gas-recovery ratio for water-flooded tight gas sands can be explained by an increase of the residual gas saturation factor during the process of development and formation of immobile gas areas in a storage. The consideration of dynamic phase permeability effect enables to reproduce the slowdown of gas speed in porous medium during gas displacement with water in comparison with water displacement with gas and to receive accordingly an appropriate quantitative dynamics of formational pressure per well based on actual measurements. Finally, this would help to increase the reliability of the forecasted technological indicators of developing a particular storage.

Study of wettability of reservoirs of oil fields by the method of X-ray tomography core

The experience of the study of wettability of oil reservoirs on the core material using the method of x-ray tomography. The process of hydrophobization of rocks significantly changes the geological and technological conditions of oil fields. Standard methods of evaluating the wettability of the reservoir do not give a fully reliable assessment of this important for the decision of technological problems of the parameter. Developed a method of evaluating the wettability of reservoirs, based on the scan x-ray emission of core samples in three states: the dry sample is saturated with water and residual water saturation. Method x-ray tomography allows to visualize the distribution pattern in the core areas with hydrophilic and hydrophobic surface. The connection of the hydrophobicity of the collectors with specific electrical resistance of rocks, which allows to assess their wettability to complexitivity data core and methods of geophysical research of wells.

Removal of asphaltene-resin-paraffin deposits of various fields

A composition comprising a hydrocarbon solvent and the additive has been developed to remove asphaltene-resin-paraffin deposits (ARPD). As an additive, it contains a block of copolymer ethylene oxide and propylene oxide based on glycerine - Laprol with a molecular weight of 3600-600. The efficacy of the compounds is identified on ARPD samples from various fields («Absheroneft» OGPU, large-sized oil-field «Muradkhanli», OGPU named after N. Narimanov and PU «Zhetybaymunaygaz»). The effectiveness of various fields ARPD removal using obtained compositions is very high. Depressor properties of the compositions were determined based on kinematic viscosity and pour point. It has been established that the presence of the prepared compounds in oil reduces the viscosity and pour point of oil produced at «Absheroneft» OGPU, OGPU named after N. Narimanov, and also there is a modification of the oil rheology at «Uzen» field from pseudoplastic flow to newtonian flow.

Evaluation of steam injection-to-bottom water injection transition at «Karazhanbas» field

The article assesses efficiency of pilot testing (PT) in the case of steam injection-tobottom water injection transition held at «Karazhanbas» field. Indicators analysis was carried out on purpose of forecast in areas where such a transition (steamwater) previously took place. It is found that the selected area in the North block is acceptable technological sub-object from the technological point of view for pilot testing on steam injection-to-bottom water injection transition. Cost-effectiveness for the selected section in the North block was calculated for the 2016-2030 period - for the base option (continued steam injection) and the option with transfer of the site to produced water injection. The results of the study showed that from both the technological and economic points of view steam injection-to-bottom water injection transition is feasible at the site.
