WORKSHOP CONTENT

1. Theory of sand production from oil/gas reservoirs

​-Fundamental equations and solutions for non-linear plasticity

+Yield surface, hardening theories, failure surface

+Simple analytical solutions useful for predicting onset of sand production

- Fundamental mechanism of unconsolidated sand production from perforations

- A simple empirical method of sand rate prediction

2. Basics of sand production mechanism

-Allowable sand production in various fields

- Five conditions to induce sand production

- Rock failure – tensile failure vs shear failure

- Sand arch effect for failed unconsolidated sandstone

- Sand particle transport

- Sand production change during a reservoir life - cavity evolution, well inclination, reservoir depletion, cyclic loading, water break-through

- Field and laboratory observations of post - failure stabilizations during sand production

- Typical sand production observed in the field

3. Methods for predicting formation strength

- UCS+Triaxial tests, *Mechanical log,

- TWC method

- Triaxial perforation stability test

- Hardness tests

- Demonstration of Sand3d/Window version

- In-situ rock strength evaluation method using the neural network 

INSTRUCTORS:

Dr. Nobuo Morita is a professor in the Harold Vance Department of Petroleum Engineering at Texas A&M University in College Station, Texas.

He has been also a consult for many major oil companies in the world. Below is a list of his contributions to the oil and gas industry:

- Clarified complex mechanism of the onset of sand production

- Created Sand3d numerical model widely used in oil companies

- Initiated screenless frac pack

- Initiated the oriented perforation technique for reducing sanding

- Patent holder of widely used stand-alone metal woven screen

- Developed a quick method to estimate in-situ stress change during reservoir depletion

- Developed new methods of casing design under geotechnical loading

- Developed new fluid-loss control materials reducing formation damage

- Initiated and developed wellbore strengthening method with his colleagues

He teaches the following graduate level courses:

- Finite element methods for application to petroleum engineering problems

- Boundary element methods for application to petroleum engineering problems

- Linear and Non-linear rock mechanics (application of geomechanics for sand production, borehole breakout, reservoir compaction and casing problems)

TIME AND VENUE

- Duration: 02 days

- Estimated time: 06th - 07th Dec 2018

- Venue: Ho Chi Minh city.

FEE

3.600.000 VND/participant (materials, tea-break included)
