In deviated wells we need to calculate true vertical depth to that formation AND place the location where the wellbore intersects the reservoir The results of this calculation allow us to correctly position reservoirs on geological sections contour maps and 3 D visualizations
Determining Depth of Cut Practical Machinist
Aug 15 2011· Determining Depth of Cut i am curious what other experienced machinist use to determine an end mill depth of cut for example i use the 2x longer then 2 square 2x2 rule that is a end mill sticking out 2 times longer then 1 4 depth of cut
Area of a trapezoid Definition formula and calculator
Area formula The area of a trapezoid is basically the average width times the altitude or as a formula where b1 b2 are the lengths of each base h is the altitude height Recall that the bases are the two parallel sides of the trapezoid The altitude or height of a trapezoid is the perpendicular distance between the two bases
