Numerical modeling of onset and rate of sand production

17/02/2018· A sand production experiment, reported by Rahmati et al.,has been performed to examine the onset and growth of sand production from a perforated cavity. A cylindrical sample 10 inches high and 6 inches in diameter has been selected for the experiment. A perforation of 0.5 inch diameter and 2 inches length is drilled centrally at the base of the sample. The sample is placed in the

Mechanical earth modeling and sand onset production

17/06/2020· This study is aimed at testing Mechanical earth modeling (MEM) and Sand onset production prediction (SOP) models using well log and core data to estimate the mechanical properties of the rock, in-situ stresses and the critical conditions at which the rock failure may occur. New numerical models were developed to predict the onset of sand production for Well X.

A New Approach to Sand Production Onset Prediction

Sand production prediction has always been an important issue when dealing with production phenomena. Knowing all significant consequences of precise sand production prediction, different methods were developed using a variety of criteria and material models were implemented to obtain more accurate results. Although sand rate prediction has become a prevalent challenge nowadays, it does

NUMERICAL AND ANALYTICAL MODELING OF SANDING ONSET

the production condition at which sand production occurs. Sanding onset prediction involves simulating the stress state on the surface of an oil/gas producing cavity (e.g. borehole, perforation tunnel) and applying appropriate sand production criterion to predict the fluid pressure or pressure gradient at which sand production occurs. In this work, we present numerical and analytical

Analytical models for onset of sand production under

The resulting analytical expressions are suitable for implementation in the analytical software for sand onset and sand mass analyses. The models are calibrated and validated against experimental data for hollow cylinder and hollow prism tests on Red Wildmoor sandstone. The analysis shows that a Drucker–Prager model is necessary to capture the experimentally observed effect of axial stress

Reasons for sand production petroblogweb

01/08/2016· Sand production is increased with onset or increased water cut because of the following reasons: Increased water cut decreases the capillary pressure, which holds sand grains in rock body. Flow of more than one phase increases the frictional flow effects. High fluid rate, to maintain the net oil production rate, results in high pressure gradient at the sand-face. Cementing material is

Sand Casting an overview ScienceDirect Topics

Some limitations of sand casting include the fact that high volume production requires a large investment in automated mold/core making and assembly equipment as well as floor space. Additionally, casting yields are often < 50%, requiring a larger amount of machining and finishing prior to use. Metallurgically, cooling rates in sand castings are often slow, especially in thick sections; this

This process is simpler than cement production; concrete is a mixture of 15% cement, 10 % water, 25% sand and 50 % small stones which are named as "Gravel". The four elements are poured in a huge mixer which rotates producing concrete. We can see that once the cement is produced by several steps and equipment, it can be used in other less complicated processes, for instance, concrete production.
