Vietnam has been producing oil more than 30 years.

Main oil reserves are contained in crystal basement rocks. World experience of study and development of such fields shows that in the absence of close analogues many tasks have to be solved for the first time and that common methods and standards have to be changed greatly. The article gives the results of the many years’ studying and observation of oil fields basements development of south offshore Vietnam.

Key words: core, porosity, permeability, formation factor, saturation parameter, water saturation

The paper identifies summarized functions: porosity/permeability, formation factor/porosity, saturation parameter/water saturation of Bashkirian stage A₄ reservoir individually for 4 structural tectonic elements distinguished within Samara Region - Sok upfold, South Tatarian dome, Zhiguli Pugachevian dome and Buzuluk low. These functions can be used to substantiate petrophysical functions of rocks’ various characteristics when estimating hydrocarbon reserves and field development project documents’ issuing in the case of low core recovery or core absence.

Tax models of a number of countries - subsoil users on terms of production sharing agreements, which may serve as an alternative for estimating oil and gas investment projects, are given.

Unified contract, based on production sharing, does not exist in the world, only a general principle is uniform. The government and investor participated at carrying out of production sharing agreements. This makes the contracts more flexible, allows to adapt production sharing agreements to any type of fields, to transfer the main economic elements of the contract from the sphere of strict legislative restrictions to the sphere of the agreements between the State and the investor. The presented models can be recommended for the economic evaluation of petroleum reserves at fields development at different stages of the investment planning.

Key words: expanding composition of cement slurry, additive for increase durability and adhesion, producing well, well completion, oil recovery troubles.

The paper presents the results of research to increase the strength characteristics of expanding composition of cement slurry for casing of wells. Increasing of strength of developed composition of cement slurry is due to the introduction of fine viscous additives the structure of the filling of the pore space in the forming cement stone. When using the developed compositions of modifying additives to cement slurries the strength characteristics of cement stone increases to 2 times.

Key words: field development, coupled clusters, fracturing, decompactification, “small” tectonics.

The development of tectonic deformation attended by decompactification zones and “small” tectonics is the special feature of geology aspects of sedimentary cover of many West Siberia fields.

During the detailed seismic investigations was found out that fault lines became strike-slip zones formed by submeridional strike of different amplitude faults that influenced reservoir formation and oil-and-gas content.

The actual material and the field data show that the diagenetic porosity, that should be considered for the well placement and the field development system, in the terrigenous reservoirs of West Siberia oil fields is developed.

Key words: well testing, injection well fracturing, fracture half-length, skin-factor, free gas separation, gas saturation, oil productivity index, operating regime, progressive increase of water cut, low oil recovery.

The present work is concerned with investigation of injection well fracturing and decrease of oil well’s productivity on the basis of well testing in Talin’s square of Krasnoleninskoe oil field.

Separation of free gas in bottomhole formation zone, concerned with bottomhole pressure decrease below saturation pressure, is the main cause of decrease of oil well’s productivity and appearance of high amount of skin-factor. Even slightl free gas appearance (gas saturation is about 5-8 percent) causes three times decrease of oil phase permeability.

Key words: carbonate rocks, proppant embedment, linear elasticity.

Relationships between closure stress and propped width loss attributed to proppant embedment in the Bashkir and Tournaisian carbonate rocks have been determined. The amount of proppant used for embedment is proportional to the fracture area and may be quite ample. It has been shown that to maintain the width and the conductivity of a fracture in carbonate rocks, proppant concentration allowance shall be in the range of 2-3 kg/m². Failure of carbonate matrix in the Bashkir starts at 20 MPa pressure, and this shall be considered in hydrafrac jobs when planning bottomhole pressure limit.
