About this Training Course
This practical, field-oriented programme provides participants with a structured approach to the planning, design and execution of acidizing treatments in sandstone and carbonate reservoirs. It begins with a review of acidizing operations, common misconceptions and the reasons why treatments fail, before focusing on formation damage, well candidate selection and the practical field calculations required to develop an effective stimulation treatment.
The programme then moves into acid formulations and laboratory testing, followed by dedicated treatment design for sandstone and carbonate formations. Participants will examine the key considerations involved in designing HF acid treatments, developing appropriate pumping schedules and addressing the different reaction and stimulation mechanisms associated with sandstone and carbonate reservoirs. Practical, step-by-step job design sessions enable participants to apply the concepts directly to an upcoming sandstone or carbonate acidizing treatment.
The course also addresses special operational considerations associated with high-water-cut and horizontal wells, together with job quality assurance and control. Throughout the programme, emphasis is placed on practical decision-making, treatment design and avoiding common causes of unsuccessful acidizing jobs. The combination of field calculations, design exercises, quizzes and practical lessons provides participants with an immediately applicable framework for improving the technical quality and effectiveness of acidizing operations.
1. What is acid stimulation in oil and gas?
Acid Stimulation helps improve fluid flow in a well. First, engineers pump acid into the rock. As a result, the acid can remove damage and help fluids move more easily.
2. What is the difference between sandstone and carbonate acidizing?
Sandstone acidizing often uses HCl and HF to remove damage. However, carbonate acidizing mainly uses HCl. Therefore, each rock type needs a different acid mix.
3. How do engineers select a well for acid stimulation?
Engineers first find out why a well has poor flow. They also check pressure, output and well condition. Then, they decide if Acid Stimulation can help.
4. What factors affect the success of acid stimulation?
Good Acid Stimulation depends on the right acid, rate and amount. In addition, rock type and heat can affect the result. Therefore, careful planning is important.
5. What is wormholing in carbonate acidizing?
Wormholing happens when acid makes small flow paths in carbonate rock. As a result, fluids can move more easily. This can also improve Acid Stimulation results.
6. How do engineers evaluate an acid stimulation treatment?
Engineers compare well results before and after Acid Stimulation. They also check output, pressure and flow. Then, they see if the treatment reached its goal.
