Well Test - Type Curves (Week 06)
WebJan 4, 2024 · The way we usually do it is to generate random parameters for some specific type of curve - say a Bezier curve, but this is not (AFAI can see) uniform in the original requirements - i.e. some curves that fit … WebOct 3, 2024 · Step1: Draw an equilateral triangle. You can draw it with a compass or protractor, or just eyeball it if you don’t want to spend too much time drawing the snowflake. It’s best if the length of the sides are divisible by 3, because of the nature of this fractal. This will become clear in the next few steps. Step2: bowling toronto
