Abstract:
To develop a kind of ideal sealing material, uniform experiments were conducted in a simulation test device after the determination of material composition and approximate ratio range. The experimental data was fitted by stepwise regression analysis and optimal mixture ratio was obtained. The reliability is perfect when the ratio of foaming agent FP, foam stabilizer WP, solid filler RX and solid filler GX is 1.5:2:3:3. Field application tests show that sealing material in the above ratio has advantages of less time waste, higher reliability and better adaptability. It has a wide application pr

The presented paper deals with the issue of influence of storage conditions on the quality of conventional fly ashes which are produced by combustion of lignite. These ashes were stockpiled for long time. A borehole for sampling was made in the fly ash stock-pile. Total depth of the borehole was 20 m. Samples of fly ashes taken from every single meter were analyzed and next mechanical properties and the volume stability of materials containing these fly ashes were tested.

According to the cluster model of glassy polymers, in the amorphous state they are natural nanocomposites of two components of a loosely packed matrix and nanoclusters immersed in it, respectively playing the role of a matrix and filler in a natural composite.

Borehole sonic measurements are an important tool to characterize formation and completion properties of hydrocarbon or water reservoirs. Such measurements can provide direct information about rock physical parameters such as permeability or elastic moduli. These properties are obtained from guided waves propagating along boreholes. The so called tube wave or Stoneley wave is a symmetric mode which compresses the fluid column leading to a piston like motion. If the medium around the borehole wall is permeable, the radial expansion of the fluid column will result in fluid flow across the boreho

The hydraulic properties of basal sediments must be known if the surge mechanism of soft-bedded glaciers is to be understood. Freezing of water-filled boreholes drives water into the subglacial bed and the associated pressure effects give information about subglacial hydraulic properties. A numerical model describing the mechanical response of an unconnected borehole and the bed beneath it to this freezing forcing was developed, using a non-linear transient viscoelastic ice rheology and an approximate model of top-down freezing.

Abstract:
Abstract The objective of this paper is to present technical specifications of a logging tool where it can identify the well integrity system failure due to various scenarios including: communication between Borehole and Tubing-Casing Annulus, or TCA (A-annulus) through one of the completion elements; leak of the tubing itself; communication between TCA and the 1st Casing-Casing Annulus, or CCA1 (B-Annulus); and communication between CCA1 and the 2nd Casing-Casing Annulus, or CCA2 (C-annulus), when the movement of unwanted fluid happened through the casing leaks. There is a described approach

Abstract:
In slow formation borehole acoustic wireline logging (WL) and logging while drilling (LWD), it is common to obtain formation shear slowness from the dispersive borehole guided flexural and quadrupole wave, respectively. Due to poor signal-to-noise ratio and/or tool eccentricity effects, it is not always possible to obtain formation shear slowness directly via conventional slowness-time-coherency (STC) methods. Consequently, a dispersion correction is frequently needed to QC and/or correct the STC result. We propose a hybrid method that allows for a model-based as well as a phenomenon-based app

Abstract:
The shallow aquifer in the Fox Creek area is hosted by the Paleocene Paskapoo Formation. The formation consists of fluvial deposits with channel-filled high-energy sandstone cutting through fine-grained, low energy overbank sediments. Three internal members are recognized, these members define three hydrostratigraphic units (two aquifers versus one aquitard). In fall 2022, three boreholes were drilled and cored. The succession is slightly dominated by sandstone with subordinate fine-grained sediments and thin coal intervals. The calcareous to non-calcareous sandstone is either tight and well c

Abstract:
The Oil, Gas and Salt Resources Library (OGSRL) is a repository for data from wells licenced under the Oil, Gas and Salt Resources Act for Ontario. It has approximately 50,000 porosity and permeability drill core analyses on bedrock cores. It also has in analogue format, geophysical logs (e.g., gamma ray, gamma-gamma density, neutron, sonic) from approximately 20,000 wells. A significant challenge for geotechnical and hydrogeological studies of the region is the accessibility of digital data on porosity and permeability.
