formation pressureの例文

• Otherwise, an " abnormal formation pressure " will result.
• Ratios vary depending upon formation pressure, depth of coal and oxidant balance.
• When filled, the container was closed, sealing the fluid sample at the formation pressure.
• Wireline logs can measure resistivity, conductivity and formation pressure, as well as sonic properties and wellbore dimensions.
• Conversely, if the mud weight is too low it will have a hydrostatic pressure that is less than the formation pressure.
• The types of shocked quartz found in surface samples from the rim of the Bloody Creek structure indicate anomalously high formation pressures.
• If the formation pressure is relatively high, using a lower density mud will reduce the well bore pressure below the pore pressure of the formation.
• Systems installed in well casing to read formation pressure directly, suspended systems, and systems built in coil ( continuous ) tubing are also available.
• The gas in the fractures is produced immediately; the gas adsorbed onto organic material is released as the formation pressure is drawn down by the well.
• Injected gas aerates the fluid to reduce its density; the formation pressure is then able to lift the oil column and forces the fluid out of the wellbore.
• This decision is often based on subsurface data such as formation pressures, strengths, and makeup, and is balanced against the cost objectives and desired drilling strategy.
• Depending on the conditions encountered ( e . g ., zones of differing formation pressure gradients ), three or four casing strings may be required to reach the target depth.
• "' Differential sticking "'is a problem that occurs when drilling a well with a greater well bore pressure than formation pressure, as is usually the case.
• Field operations included the acquisition of a full suite of Wireline logs, over 150 meters of continuous core, and formation pressure test data and concluded field operations on February 21, 2007.
• LWD tools are able to measure a suite of geological characteristics including density, porosity, resistivity, acoustic-caliper, inclination at the drill bit ( NBI ), magnetic resonance and formation pressure.
• They are individually designed to provide any number of particular services, such as evaluation of the rock properties, the location of casing collars, formation pressures, information regarding the pore size or fluid identification and sample recovery.
• And this well design leaves little room for error : if the drillers are forced to run yet another casing string on account of unexpected formation pressures or hole conditions, then the target formation may be impossible to reach.
• In case of drilling a wildcat or exploratory well ( often the formation pressures are not known accurately ) the bit suddenly penetrates into an abnormal pressure formation resulting the hydrostatic pressure of mud become less than the formation pressure and cause a kick.
• In case of drilling a wildcat or exploratory well ( often the formation pressures are not known accurately ) the bit suddenly penetrates into an abnormal pressure formation resulting the hydrostatic pressure of mud become less than the formation pressure and cause a kick.
• The measurements are made referenced to " TAH "-True Along Hole depth : these and the associated analysis can then be used to infer further properties, such as hydrocarbon saturation and formation pressure, and to make further drilling and production decisions.
