DIGITAL ANALYSIS TECHNOLOGIESFOR TIGHT AND SHALE RESERVOIRS

Shale play Bazhenov formation

Low-permeability rocks

Fractured carbon, including clay

IntroVision is an innovative engineering digital petrophysics company, focused on researching tight oil and gas reservoirs

IntroVision - One of the four companies in the world, owning unique digital petrophysics technologies for tight oil reserves investigations:

PROBLEM

SOLUTION - DIGITAL CT RESEARCH

Conventional core analysis :

Core samples CT-based lab Mathematical modeling Research results

SAAS

Enhanced oil and gas recovery

• time-consuming• expensive

• destroys the samples• does not apply to the study of complex fields

Field research of core samples

(IntroVision ML™) Express well-side core

analysis

Digital analysis (IntroVision R&D)

CT and NMR experiments

Laboratory studies (IntroVision Lab) Experiments and measurements in atmospheric and

reservoir conditions

COMBINATION OF TRADITIONAL AND DIGITAL APPROACHES:

• Open, close and effective porosity analysis

• Pore size distribution measurement for open, close and effective pore volume

• Definition of porosity and permeability properties for fractures

• Researches of rock interaction with different mediums (acid treatment, gel, concrete, polymer solution)

BENEFITS FOR THE CONSUMER:

NON-DESTRUCTIVE ANALYSIS

REDUCTION OF ACQUISITION TIME AND RECEIVING WIDER ARRAY OF DATA COMPARED TO CONVENTIONAL METHODS

BEST QUALITY OF BAZHENOV FORMATION AND SHALE RESEARCH IN THE INDUSTRY

EFFECTIVE STUDY OF ENHANCED OIL RECOVERY METHODS
