    CORE PROVIDING IMPROVED INFORMATION ON ROCK PROPERTIES   

Services
RESEARCH AND TECHNICAL SERVICES 
Prior to the contractual work, geological, geophysical and technological information on the well is gathered. ..

SCOPE OF THE RESEARCH AND TECHNICAL SERVICES TO BE PROVIDED 
Depending on the Clients needs and required final result, the Research and Production Company SibBurMash can offer the following service options for low invasion coring and core analysis ..

MAJOR TECHNICAL PARAMETERS OF CORE BARRELS ACCORDING TO TU 3664-031-27005283-98 
Core barrels are equipped with centralizers, diameter of which is selected depending on the diameter of the core bit to be used ..

REGULATORY COMMISSION BASIS AND METHODOLOGY USED FOR LOW INVASION CORING 
The order of operations on low invasion coring is summarized in Methodic Guidelines for Low Invasion Coring and Core Analysis. ..

NEW PERSPECTIVE TECHNOLOGIES 
Pressurized core is a core obtained with sealed pressurized core barrels which, after the core is separated from the bottom hole, can provide sealing of the core receiver both in the bottom and top (if necessary). ..

It is well known that CORE is a major source of information on rock properties. As CORE provides visual and direct study of rocks, it can give 70-80% of the total information provided in the course of exploratory operations.

However, till recent time such level of information could be obtained only when coring was performed with oil-base mud which was considerably more expensive, fire hazardous and dangerous to the environment compared to water-base mud. Still, until recently, following the requirements of the State Commission on Reserves (SCR), oil companies had to use oil-based mud for coring in reservoir evaluation (appraisal) wells.

Trying to find alternative methods providing for use of water-based mud and complying with the SCR requirements, specialists of the Research and Production Company SibBurMash have developed special technologies for drilling and coring with water-base mud. These technologies exclude the negative effect of using water-base mud, minimize mud filtration into the core sample and preserve formation water saturation Sw in its pore space.

In order to achieve the above mentioned aims, a series of core barrels KIM of different standard sizes has been developed. With these core barrels it is possible to obtain cores providing improved information content, i.e. having preserved structure and texture, maximum possible preservation of the initial fluid saturation and core recovery of not less than 90% (not less than 75% from unconsolidated formations). This improved information level is provided also by the advanced technologies for on-site core express-analysis and processing, and by appropriate core study techniques developed jointly by the Tyumen research and development companies SibBurMash, SibCor and Tyumengeophysica.

The basic concept of their field services is Core quality should provide solutions for geological tasks.

This concept is realized by the offered research, design work and services.
