The oil and gas industry uses many jargons, acronyms and abbreviations. Obviously, this list is not anywhere near exhaustive or definitive, but this should be the most comprehensive list anywhere. Mostly coming from user contributions, it is contextual and is meant for indicative purposes only. It should not be relied upon for anything but general information.
For example, a person who eats approximately 2,000 calories per day should take in about 250 grams of carbohydrates (2,000 divided by 2 = 1,000 and 1,000 divided by 4 = 250).
Whatever calories that have not been allotted to protein and fat intake will make up total daily carbohydrate intake. For our subject in question, this leaves 2400 (1000 + 495) = 905 kcals per day for carbohydrate intake. This equates to 225g of carbohydrates per day.
