What is LNG? Liquefied natural gas, or LNG, is natural gas in its liquid form. When natural gas is cooled to minus 259 degrees Fahrenheit (-161 degrees Celsius), it becomes a clear, colorless, odorless liquid. LNG is neither corrosive nor toxic. Natural gas is primarily methane, with low concentrations of other hydrocarbons, water, carbon dioxide, […]
Natural gas is a subcategory of petroleum that is a naturally occurring, complex mixture of hydrocarbons, with a minor amount of inorganic compounds. Geologists and chemists agree that petroleum originates from plants and animal remains that accumulate on the sea/lake floor along with the sediments that form sedimentary rocks. The processes by […]
PROCESS DESCRIPTION OF GAS DEHYDRATION The principle of glycol dehydration is contacting a natural gas stream with a hygroscopic liquid which has a greater affinity for the water vapor than does the gas. Contactor pressure is subject to economic evaluation usually influenced by water removal duty, required water dewpoint, vessel diameter and wall thickness. After […]
Liquefied petroleum gas (LPG) includes propane, butane, butadiene, isopropane, propylene, and vinyl chloride monomer, which are all by-products of the production of oil and natural gas. LPGs have a variety of uses including as a cooking/heating fuel, refinery feedstock, automotive power, and numerous other plastics and chemicals applications. another definition of LPG is that LPG […]
The use of measurement and logging while drilling has matured a great deal in the last 10 years. The use of these tools that have been developed for the oil and gas industry for use in primarily sedimentary depositional environments must be investigated in light of the goals set for EGS systems. Let us first […]
Directional Drilling The glossary of terms used in directional drilling has been developed by the API Subcommittee on Controlled Deviation Drilling under the jurisdiction of the American Petroleum Institute Production Department’s Executive Committee on Drilling and Production Practice. The most frequently used terms listed below. Angle of inclination (angle of drift). The angle, in degrees, […]
Surface Production Equipment – Well head – X-mass tree Subsurface Production Equipment – Tubing – Packer – Bridge Plug – Safety Valve Production Wellheads The surface termination of a wellbore that incorporates facilities for installing casing hangers during the well construction phase. The wellhead also incorporates a means of hanging the production tubing […]
Removing water from crude oil often requires additional processing beyond gravitational separation. In selecting a treating system, several factors should be considered to determine the most desirable methods of treating the crude oil to contract requirements. Some of these factors are: Tightness of the emulsion. Specific gravity of the oil and produced water. Corrosiveness of […]
Drilling Bits when talking about oil well drilling, it is important to know How well the drilling bit drills depends on several factors, such as the condition of the drilling bit, the weight applied to it, and the rate at which it is rotated. Also important for a drilling bit performance is the effectiveness of […]
Crude Oil Price First of all we have to understand the Classification of Petroleum Products. The petroleum products that may be subject to evaluation can be grouped as: crude oil – natural gas – associated products Crude oil is a liquid composite of many hydrocarbon compounds that, depending on the composition, has differing properties such […]
Drilling Fluid Definitions and General Functions Results of research has shown that penetration rate and its response to weight on Drilling Bit and rotary speed is highly dependent on the hydraulic horsepower reaching the formation at the bit. Because the drilling fluid flow rate sets the system pressure losses and these pressure losses set […]
The sequence of operations is as follows when a land well is drilled: – Prepare location before rig arrives. – Dig cellar. – Install conductor pipe. – Prepare support pad for rig, camp, etc – Build roads, fencing, dig pits. – Sometimes drill water well. – Move rig on to location, rig up and prepare […]
