Exercise chapter (Oil and Gas Properties) How does API gravity (in degrees) relate to density (as measured by specific gravity)? to viscosity? API lớn mật độ nhỏ ngược lại mật độ lớn API nhỏ Độ nhớt biểu sức cản dịch chuyển phần tử dầu khí di động nhỏ Độ nhớt cao API nhỏ ngược lại API cao độ nhớt What is condensate? How does it form? Condesate khí ngưng,dầu ngưng Các hydrocacbon lỏng thành phần dầu thô nhẹ sinh dạng khí điều kiện vỉa chứa đất ( nhiệt độ áp suất cao) ngưng tụ thành chất lỏng điều kiện mặt đất Các khí ngưng tụ diển hình thường chất lỏng không màu có màu vàng nhạt với ánh màu đỏ 3.Circle one Paraffins are/ are not saturated with respect to hydrogen are/ are not pure hydrocarbons Resins/ Asphaltenes are/ are not saturated with respect to hydrogen are/ are not pure hydrocarbons Aromatics are/ are not saturated with respect to hydrogen are/ are not pure hydrocarbons Naphthenes ed with respect to hydrogen are/ are not pure hydrocarbons In addition to the four major constituents of crude oil (paraffins, resins/asphaltenes, aromatics and naphthenes), there are three major elements and one group of compounds which are also found as trace amounts within hydrocarbons What are they? Ngoài có thêm nguyên tố là: Nitrogen Sulfur Oxygen Oranometals ( vanadium ,nickel ,…) 5.What are the four major causes for alteration of crude oil? Nhiệt trưởng thành Quá trình loại asphalt Quá trình suy giảm rửa lũa Quá trình suy giảm hoạt động vi khuẩn 6.Fill in the following blanks using one (or more) of the gas categories: A Carbon dioxide; B Hydrogen sulfide; C Inert gases _A+B can form both inorganically and organically _B is poisonous and highly corrosive _C_ can usually be found in trace amounts in hydrocarbons, but not often is there more than a trace _A forms during the oxidation of organic material _B_ is the controlling factor in classifying gas or oil as sweet or sour _B is often associated with evaporites within a hydrocarbon province _C can only form inorganically (for example near volcanic plugs) Match each of the "Gas" terms above with its definition below by placing the correct letter in the space provided G LPG is comprised of heavier hydrocarbon gases stored under pressure in a liquid form C Associated is natural gas which overlies crude oil Gas as a gas cap D Dry Gas is defined as mostly methane gas H LNG is hydrocarbon gas (usually methane) which is compressed into liquid for storage and transportation A Free Gas is in a gaseous phase in the subsurface reservoir and remains in a gaseous phase when produced E Wet Gas contains heavier hydrocarbon gases as well as methane F NGL are the hydrocarbon liquids which are separated from the produced-gas stream B.Dissolved Ga is in solution within crude oil in the subsurface reservoir, but bubbles out of solution when pressure and temperature drop Methane is the lightest natural gas and has a formula of CH4 What are the next heavier hydrocarbon gases, and what are their formulas? Solution Ethane C2H6 (C2) Propane C3H8 (C3) Butane C4H10 (C4)
