Introduction

Este curso abrange os principais aspectos da estimulação de poços, cujo principal objetivo é reparar danos de formação para restaurar / aumentar a produção. O curso começa apresentando os conceitos básicos para estimulação, execução e acompanhamento do trabalho.

A discussão é realizada sobre o dano à formação e seu efeito no bom desempenho e no planeamento dos tratamentos de estimulação com ácidos. O foco é dado às principais causas de danos à formação (danos durante a perfuração, cimentação, furagem, produção e trabalho sobre os poços) e como estes podem ser identificados. 

Este curso de destaca:

  • Dano de formação (Definição, mecanismo, reparação, etc.)
  • Acidificação (Acidificação da formação, Fracturação com Ácido, etc.)
  • Visão geral da fracturação hidráulica
  • HSE e estimulação Você se concentrará em grandes áreas de técnicas de estimulação com acidos. O curso se concentra tanto em conceitos teóricos quanto em experiência prática no campo. Operações  com Tubo Coiled também serão discutidas em detalhes, devido à sua importância na colocação de ácido e nos tratamentos da formação

Objectives

Até o final do curso você ficará confiante em sua compreensão de:

  • Introduction to stimulation operations
  • Formation damage mechanisms and their identification
  • Brainstorming on skin damage
  • Acids reactions and their selection for carbonates and sandstones
  • Acids and additives used in matrix stimulation
  • Candidate well selection
  • Acid treatment design
  • Acid placement and diverting technologies
  • Acid displacement and flow back
  • Laboratory tests
  • Acid fracturing design basics
  • HSE and acidizing operations
  • Safety & quality assurance

Training Methodology

O curso será apresentado usando slides devidamente planeados, alguns com animação e vários vídeos em questões relevantes. Um manual impresso contendo todos os slides e / ou eletrônicos em PDF será entregue a cada participante. Os métodos de ensino incluem também cálculos sobre questões relacionadas. Vários exemplos de programas de estimulação serão apresentados.
