The average geological parameters and oilfield development Indicators of Romashkinskoye field areas are given. The effect of the fluid withdrawal rate on the efficiency of development is Investigated. The comparison of actual and predicted (obtained by V.F. Baziv charts) development indicators of some areas are presented. It is noted, that the relatively high efficiency of waterfloodlng of Romashkinskoye field objects is provided by active control of the productive strata flushing processes during the entire period of development.

It is shown that well logging may not adequately show whether cement is well bonded with the casing and formation. To achieve better accuracy in evaluation of cement bond quality it is recommended to perform cement-bond logging before and after the production string is run into the well and after cementing jobs are accomplished. Some modifications have been proposed for interpretation of gamma-gamma logging data using Scanning GR-Thickness Fault Detector. In particular it Is suggested to introduce anisotropy factor for density measurements of cement sheath around the casing.

Expandable casings strings applied by Tatneft on a commercial scale allowed complete exclusion of intermediate casing strings from the well designs In the Volga-Ural oil-producing region. Underway is research and pilot tests of expandable systems to isolate trouble zones as thick as 500-1000 m. For expanding of casing strings mechanical and hydraulic expansion mandrels are used, along with hydraulic jack, anchor, and by-pass valves.

Historical development, current trends and future outlook for enhanced oil recovery (EOR) methods In Tatneft OAO determined by oil-field development issues Is presented. The company proved to have a wide range of efficient, available and evolving, EOR techniques for various applications. The paper offers a special focus on application of EOR techniques for development of hard-to-recover reserves. A wide application of EOR methods to unconventional oil reserves development requires government motivation by means of lower mineral extraction tax rates. As for the company it should keep updating its EOR techniques.
