A heavy-duty retrievable packer assembly that can be run in to isolate the wellbore of a new well in the event of suspended activities, for example, during a severe storm. An on-off disconnect feature enables the storm packer to be set at a safe depth while using the weight of the string below the packer to maintain the set and hang off the drillstring to avoid pulling all the way out of the hole.
Industry:Oil & gas
A heavy-duty downhole tool used to restore the internal diameter of collapsed or buckled casing. Casing rollers generally are configured with an incremental series of rollers that act to gradually form the damaged casing to the desired size. Depending on the degree of damage and the requirement for wellbore access below the site of damage, the nominal diameter of the casing roller and repaired wellbore may be significantly less than the nominal drift diameter of the original casing string.
Industry:Oil & gas
A highly simplified description of a geological scenario. Although sometimes used for "quick and dirty" simulation models, this description is often not appropriate for detailed or accurate work. Generally, layer-cake geometry is an oversimplification of actual structure and stratigraphy of a reservoir. It assumes that the reservoir comprises a stack of conformable layers.
Industry:Oil & gas
A grid pattern laid over a representation of fractures. The number of boxes that contain a fracture is counted and plotted against the box size on logarithmic scales. The slope of the line is equal to minus the fractal dimension. This is sometimes referred to as the box "dimension. "
Industry:Oil & gas
A group of data points having similar characteristics. These points are usually found by cluster analysis, and are sometimes used to determine electrofacies from wireline data.
Industry:Oil & gas
A group of round hydrocarbon chains formed when the surfactant concentration in an aqueous solution reaches a critical point. The micellar costs depend upon the cost of oil, since many of these chemicals are petroleum sulfonates.
Industry:Oil & gas
A group of tanks that are connected to receive crude oil production from a well or a producing lease. A tank battery is also called a battery. <br><br>In the tank battery, the oil volume is measured and tested before pumping the oil into the pipeline system.
Industry:Oil & gas
A heavy steel bar that is dropped through the tubing or running string to fire the percussion detonator on a tubing-conveyed perforating (TCP) gun assembly. The drop bar must be capable of falling through the string with sufficient speed to impart the necessary force for detonation. Therefore, this method of firing is best suited to vertical or slightly deviated wellbores where there will be minimal drag or friction effect.
Industry:Oil & gas
A graduated tape use to measure, or strap, producing tanks. The measurements are used to generate a tank table, which describes tank capacity.
