The power of TDS technique for well test interpretation: a short review [PDF]
Journal of Petroleum Exploration and Production Technology, 2018 Either pressure-transient analysis or rate-transient analysis can be interpreted by four methods: (1) conventional straight-line analysis, (2) type-curve matching procedure, (3) ACMM (automatic computer modeling matching), and (4) TDS (Tiab’s direct ...

PRESSURE AND PRESSURE DERIVATIVE ANALYSIS FOR LONG NATURALLY FRACTURED RESERVOIRS USING THE TDS TECHNIQUE [PDF]
Dyna, 2010 Normalmente, en una formación heterogénea, el periodo de transición del flujo fracturasmatriz toma lugar durante el flujo radial. Sin embargo, dependiendo del valor del parámetro de flujo interporoso, dicha transición puede ocurrir antes o después del ...

THz-TDS Techniques of Thickness Measurements in Thin Shim Stock Films and Composite Materials [PDF]
Applied Sciences, 2021 Terahertz wave (T-ray) scanning applications are one of the most promising tools for nondestructive evaluation. T-ray scanning applications use a T-ray technique to measure the thickness of both thin Shim stock films and GFRP (glass fiber-reinforced plastics) composites, of which the samples were selected because the T-ray method could penetrate the ...

APPLICATION OF TDS TECHNIQUE TO MULTIPHASE FLOW
CT&F - Ciencia, Tecnología y Futuro, 2008 Although, the radial difussivitity equation has been solved for a single-fluid phase flow, in some cases more than one phase flows from the reservoir to the well; therefore, the single-phase solution has been previously extended to multiphase flow without losing a significant degree of accuracy.

Application of TDS technique to developed reservoirs
Journal of Petroleum Science and Engineering, 2006 Abstract Well test interpretation methods for a single well in infinite reservoirs may not be suitable for those wells when their pressure is affected by other wells operating in the same reservoir. This effect becomes more significant as both the flow rate and the test duration increase.

DETECTION OF MELANOMA USING IMAGE PROCESSING TECHNIQUES DRIVEN TDS INDEX [PDF]
Journal of Environmental Science, 2019 Skin cancer exists in different forms such as: Melanoma, Basal and Squamous Cell Carcinoma, among which Melanoma is the most dangerous and unpredictable skin cancer. In this paper, we implement an image processing technique for the detection of Melanoma skin cancer, in which the input to the system is the skin lesion image. This image proceeds with the

Trapping and Detrapping Mechanisms of Deuterium in SiC Studied by XPS and TDS Techniques
MATERIALS TRANSACTIONS, 2005 The elucidation of the trapping and detrapping mechanisms of hydrogen isotopes in SiC is one of the most critical issues for future fusion reactors if SiC is used as the first wall and structure material. In this study. 1keV deuterium (D 2 + ) ions were implanted into SiC and the chemical states of C and Si were evaluated by X-ray photoelectron ...

Kendali TDS nutrisi hidroponik deep flow technique berbasis IoT menggunakan fuzzy logic
JITEL (Jurnal Ilmiah Telekomunikasi, Elektronika, dan Listrik Tenaga), 2021 Pada sistem hidroponik deep flow technique (DFT), setiap umur dan jenis tanaman yang ditanam memerlukan total dissolved solids (TDS) dengan satuan ppm yang berbeda serta kegagalan tanaman dalam bertumbuh dapat terjadi jika nilai TDS tidak terpantau dengan baik. Tujuan dalam penelitian ini untuk membuat sistem kendali nilai TDS dengan metode fuzzy logic

Systematic Characterization of High-Dielectric Constant Glass Materials Using THz-TDS Technique
, 2023 High-dielectric constant glasses are prerequisite for developing terahertz (THz) components and systems. Oxyfluorosilicate (OFS) glasses have been developed and their THz properties have been characterized by using THz-time domain spectroscopy (THz-TDS) measurements.
