I have worked in the oilfield since 1991. Math has always been a difficult downfall for me. For the longest time I have had no desire to learn the math. How ever I have worked my way up the ladder taking a drillers position. Drilling only shallow gas wells that really required no math if any at all. Recently I had surrendered my drillers position going back to rough necking. Unfortunately I am feeling the physical toll that it has taken on my body and now looking to go back to being a driller but not wanting to do so until I have proper knowledge of understanding & working out the math of simple basic formulas and calculations. PLZZZZZ!!!!! Help!!!
