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 ...

APPLICATION OF TDS TECHNIQUE TO MULTIPHASE FLOW EXTENSIÓN DE LA TÉCNICA TDS A FLUJO MULTIFÁSICO

CT&F Ciencia, Tecnología & 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 ...

PRESSURE AND PRESSURE DERIVATIVE ANALYSIS FOR LONG NATURALLY FRACTURED RESERVOIRS USING THE TDS TECHNIQUE

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 ...

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.

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

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

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 ...

Aplication of the TDS technique for determining the average reservoir pressure for vertical wells in naturally fractured reservoirs

CT&F - Ciencia, Tecnología y Futuro, 2005
In this study pressure test analysis in wells flowing under constant wellbore flowing pressure for homogeneous and naturally fractured gas reservoir using the TDS technique is introduced. Although, constant rate production is assumed in the development of the conventional well test analysis methods, constant pressure production conditions are sometimes

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.
