LPG BASED FRACTURING TECHNOLOGY FOR DEVELOPMENT OF GAS AND OIL FIELDS

Research Summary

One of the most effective method of development of gas and oil fields with complicated hydrocarbon production conditions is hydraulic fracturing. However, utilization of the most commonly used water-based fracturing fluids is not always expedient, for instance for shale oil and gas, reservoirs with low formation pressure, containing water-sensitive minerals, low-permeable or weakly consolidated rocks. On the base of foreign experience, it can be concluded that the most suitable and novel frac fluid is hydrocarbon one based on liquefied petroleum gas or light hydrocarbons. LPG based fracturing fluid is the mixture of liquefied propane and butane.

LPG-based fracturing allows to obtain sizable increase of cumulative production per one well job. Cumulative production per well fractured with LPG-based fluid exceeds the one resulted from traditional aqueous fracturing more than by 2 times. The most part of positive effect results from increase of effective well length on 2 times in comparison with aqueous fracturing. It must be noted that residual conductivity of the fracture obtained during LPG-based fracturing is more than 90% whereas conductivity of the fracture in the case of aqueous fracturing doesn’t exceed 40%. Complex approach towards the development and implementation of LPG-based fracturing technology is presented in the work. This complex comprises such stages as the determination of reservoir properties, development planning, elaboration and comparison of object development alternatives, implementation, monitoring and control. Elaborate work plan and awaited results have been prepared and worked through for each stage of the project.

Proposal Title

DIGITAL PLATFORM FOR RESERVES AND RESOURCES MONITORING

Research Summary

Permanent Model of Reserves and Resources Monitoring “ERA:ProActiv” is an innovative tool for integration of information repositories, current approaches and approved methods for assessing the resource base and its continuous analysis on the common platform.

The main objective of the project is creation of the single software for analyzing the resource base in the “online” mode and defining optimal solutions for Company’s resource base growth. Embedding the software solves the challenge of automatization of reserves and resources analysis in constantly changing external economic conditions. The project is the part of the Company’s Technology Strategy, which has united the projects aimed at improving efficiency of oil and gas production, development of new reserves and fulfillment of the Company’s strategic plans. The total effect of implementing projects under the Technological Strategy is expected to result in more than 20 million tons of additional production and 100 million tons of additional reserves under development by 2025.

Proposal Title

A SLUG FLOW TESTING METHOD BASED ON THE ATTENUATION
CHARACTERISTIC OF ULTRASOUND ECHO OF GAS-LIQUID TWO-PHASE FLOW WALL

Research Summary

A new method for studying slug flow is presented in this project. Based on the characteristics of good penetration and non-contact of ultrasonic wave, a new non-intrusive measurement method for gas-liquid two-phase flow is proposed by taking the attenuation spectrum of ultrasonic aftershocks formed by multiple round-trip propagation in the pipe wall as the research object.
