International Well Control Forum (IWCF) has provided great-useful learning material, which is IWCF Drilling Calculation Part 1 – 3, to all drilling related personnel. We will review all of them and see the content inside.

Below download links to all learning materials and reviews.

**IWCF Drilling Calculation Part 1 – Introduction to Calculations**

The part 1 consist of basic mathematics that you need to know in order to work out any mathematical questions. This cover from very beginning for people who don not have a strong background in mathematics before. The content is very well written and easy to understand. There is also the answer section which you need to use to check the anwer. The content of the first part are listed below;

Section 1 Whole Numbers

Section 2 Estimating and Rounding

Section 3 Basic mathematical calculations and the use of the calculator

Section 4 Fractions, decimals, percentages and ratios

Section 5 Units of measurement

Section 6 Mathematical symbols, equations and arithmetical operations

Section 7 Introduction to solving equations and the use of formulae

Section 8 Converting and conversion tables

**IWCF Drilling Calculation Part 2 – Areas and Volume**

The second part is about areas and volume. For the area calculation, you will learn how to determine area and estimate area with various shapes and there are discussion about units related in areas calculation. For the volume calculation part, you will learn how to define volume and capacity, how to calculate volumes of various shapes and the application on the rig. Moreover, you will learn about pump output, stroke, time which are very important to the well control calculation. The solution of this part is also provided. The details of this section is shown below;

Section 1 Calculating areas

Section 2 Calculating volumes

Section 3 Oilfield volumes

Section 4 Borehole geometry – Surface BOP operations

Section 5 Borehole geometry – Subsea BOP operations

Section 6 Pump output, strokes, time

Section 7 Volume and pump strokes – kill sheet calculations

Section 8 Trip monitoring calculations

**IWCF Drilling Calculation Part 3 – Well Control**

The third part will cover various concepts of well control so learner must have good basic calculation background. You will learn about hydrostatic pressure and related oilfield terminology in well control. The next part is about the circulating system on the rig. The last two parts are about introduction to well control relating to kick prevention and detection, primary well control and secondary well control. There are many examples which will help you understand the key concepts and you need to practice the calculations as well.

The details of the third part is shown below;

Section 1 Hydrostatic pressure

Section 2 Primary well control

Section 3 The Circulating System

Section 4 Introduction to well control (kick prevention and detection)

Section 5 Secondary well control – An introduction to kill methods
