Conduct a survey inside a borehole to gather information about the subsurface formations. Logs typically consist of several curves on a long grid that describe properties within the wellbore or surrounding formations that can be interpreted to provide information about the location of oil, gas, and water. Also called well logs, borehole logs, wireline logs, gravity logs, acoustic logs. >
The results of a survey which gathers information about the subsurface formations. Logs typically consist of several curves on a long grid that describe properties within the wellbore or surrounding formations that can be interpreted to provide information about the location of oil, gas, and water. The measurement versus depth or time, or both, of one or more physical quantities in or around a well. The term comes from the word “log” used in the sense of a record or a note. Wireline logs are taken downhole, transmitted through a wireline to surface and recorded there. Measurements-while-drilling (MWD) and logging-while-drilling (LWD) logs are also taken downhole. They are either transmitted to surface by mud pulses, or else recorded downhole and retrieved later when the instrument is brought to surface. Mud logs that describe samples of drilled cuttings are taken and recorded on surface.
A local utility that sells natural gas to consumers within the city or region that the utility serves. LDC’s are usually regulated at the state level
A loan agreement is typically used by a bank, another financial investor or partner to finance all or part of an oil and gas project. Compensation for funds advanced is limited to a specified interest rate. The tender does not participate in profits earned by the project above the agreed upon interest rate. There is normally a fixed repayment schedule for the amount advanced and repayment of the obligation is made before any return to equity investors. Risk is limited to default of the borrower or failure of the project and thus the lender does his utmost to ensure that every aspect of the project is economically sound before agreeing to lend the money requested. Variations in production, market prices and sales do not normally affect compensation. Reserves are not recognized under this type of agreement
The practice of altering the pattern of energy use so that on-peak energy use is shifted to off-peak periods. Load shifting is a fundamental demand-side management objective
