Abstract

This patent describes a method for monitoring the hydraulic fracturing of a subsurface formation of interest. It comprises: logging a subsurface formation through a measurement of delayed gamma rays from the neutron activation of a characteristic element of the formation, injecting a fracturing fluid into the formation to hydraulically create a fracture within the formation, injecting a proppant into the fracture containing the element which emits delayed gamma rays in response to neutron activation, logging the proppant containing the fractured formation through a measurement of delayed gamma rays from the neutron activation of the proppant containing fractured formation, and identifying the extent of proppant deposition within the fractured formation from the difference in the delayed gamma ray measurements of the formation before and after the proppant injection.

Final Report DE-FE0031785 Mohsen Ahmadian, Ph.D. Demonstration of Proof of Concept of a Multiphysics Approach for Real-Time Remote Monitoring of Dynamic Changes in Pressure and Salinity in Hydraulically Fractured Networks

Technical Report Ahmadian, MOHSEN

Hydraulic fracturing has evolved into a multistep process with varying flow rates, carrier fluids (e.g., gel or slickwater), proppant loadings, and proppant grain sizes. As a result, primary recovery from a hydraulically fractured tight-oil reservoir is often a tiny fraction of the original oil in place, ranging between 5 and 10%. As stated in the FOA1990, “part of this problem is due to the inability of current well completion processes to effectively stimulate the entire reservoir volume in contact with the wellbore. Innovative technologies are needed that can help improve the effectiveness of reservoir completion methods, maximize stimulated reservoir volumes,more »« less

A Systematic Interpretation of Subsurface Proppant Concentration from Drilling Mud Returns: Case Study from Hydraulic Fracturing Test Site (HFTS-2) in Delaware Basin

Journal Article Maity, Debotyam; Ciezobka, Jordan - Proceedings of the Unconventional Resources Technology Conference (URTeC)

The aim of this study is generation and validation of a proppant log using analysis of drilling mud returns for child wells. Proppant log provides qualitative as well as quantitative insights into spatial distribution of proppant sand particles from prior stimulation of parent wells. While the basic methodology was developed and formalized during analysis of material collected from through fracture cores at Hydraulic Fracturing Test Site in Midland Basin (HFTS – 1), the test wells at HFTS – 2 in the neighboring Delaware Basin allowed the opportunity to validate the workflow on actual mud return samples from subsurface.

Method for formation stimulation in horizontal wellbores using hydraulic fracturing

Patent Jennings, Jr, A

This patent describes a method for stimulating a formation penetrated by a horizontal wellbore. It comprises: perforating a horizontal wellbore along its top side at desired intervals so as to enable fluid communication with the formation; fracturing hydraulically the formation through perforations in the wellbore with a fracturing fluid containing a substantially lightweight proppant which has a density substantially equal to the fluid thereby creating a fracture within a first interval of the formation and maximizing multilayer proppant placement within the fracture; releasing hydraulic pressure on the formation thereby causing the fracture to be propped with the proppant; placing ballmore »« less
Cold fluid hydraulic fracturing process for mineral bearing formations

Patent Perkins, T

A method is described for hydraulically fracturing a subterranean formation region to stimulate the production of recoverable fluids comprising the steps of: providing a wellbore extending into the formation region and means for conducting fluid between the wellbore and the formation region; injecting a relatively cold liquid into the formation region through the wellbore at a rate which will result in substantial cooling of the formation region below the nominal preinjection temperature of the formation region so as to lower the stresses exerted within the formation region; increasing the pressure of the cold liquid being injected at a predetermined timemore »« less
Geophysical data from boreholes DM1, DM2, DM3, and DM3a, New Hydraulic Fracturing Facility, Oak Ridge National Laboratory, Oak Ridge, Tennessee

Technical Report Haase, C

A comprehensive suite of geophysical logs was obtained from four deep monitoring boreholes at the New Hydrofracture Facility. The logging was an attempt to obtain stratigraphic, structural, and hydrologic information on the subsurface environment surrounding the hydrofracture facility. Logs obtained include caliper, gamma, neutron, density, single-point resistance, long- and short-normal resistivity, spontaneous potential, temperature, acoustic velocity, variable density, and borehole televiewer. Analysis and interpretation of the geophysical logs allowed the stratigraphic section at the facility to be determined and, by comparison with calibrated geophysical logs from borehole ORNL-Joy No. 2, allowed detailed inferences to be drawn about rock types andmore »« less
