The development of a reservoir model by the use of objects. Reservoir models may be developed by adding together a series of objects (such as channel belts) in a fashion that honors the well data (logs, cores, etc. ) and satisfies all the geostatistical requirements of the model. Such models may be used to simulate the behavior of the fluids in a reservoir.

The deterioration of metal components resulting from contact with a gas or solution containing carbon dioxide.
Industry:Oil & gas
The deterioration of metal due to contact with carbon dioxide or similar corrosive agents, but excluding hydrogen sulfide (H<sub>2</sub>S). Sweet corrosion typically results in pitting or material loss and occurs where steel is exposed to carbon dioxide and moisture.

The determination of the location of a leak in a pipeline. In onshore operations, this can be done by external detection or by using material balance leak-detection systems. In offshore operations, the task is more difficult because of the lack of inlet flow-rate measurements and the considerable solubility of natural gas in seawater at high pressures and low temperatures (seafloor level). <br><br>In deepwater operations with multiphase flow, indications of a leak may not be present at the ocean surface or it could be considerably displaced from the site of origination. In these circumstances, an energy-balance technique based on the changes in frictional losses through the pipeline is a powerful tool.
Industry:Oil & gas
The depth to which pressures are corrected to adjust for differences in elevations at which pressure measurements are made in different wells or at different times.
Industry:Oil & gas
The depth, or distance from surface, that the fluid in a well incapable of natural flow will reach under static conditions.

The description of a proposed wellbore, including the shape, orientation, depth, completion, and evaluation. Well plans might be relatively simple for vertical wellbores. Directional or horizontal wellbores require more detailed planning about where to land the well and begin directional drilling, how long the directional or horizontal section should be, and how to evaluate and complete the well. Shale gas wells, many of which are horizontal wells, require highly detailed well plans to optimize production from reservoirs that are vertically and laterally heterogeneous. <br>

The depth of the last reliable reading of a log. For the normal bottom-to-top survey, the last reliable reading often occurs just before the logging tool enters the casing. With several logging tools in a tool string, the last readings will be at different depths, depending on the measure point of each measurement.
Industry:Oil & gas
The depth at which the tool string is picked up off the bottom of the well during a wireline logging survey. Pick-up can be observed by an increase in cable tension and by the start of activity in the log curves. When the logging tool is lowered to the bottom of the well, it is common practice to spool in some extra cable. When the cable is pulled back out, the tool remains stationary before it is picked up off the bottom. During this time the log readings are static but the depth, which is recorded by the movement of the cable, is changing.
