- Company Profile:
An organic acid used in the stimulation of high-temperature oil and gas wells in which conventional hydrochloric acid systems cannot be adequately inhibited, or where contact time with tubulars is likely to be extended.
Industry:Oil & gas
An organic acid used in oil- and gas-well stimulation treatments. Less corrosive than the commonly used hydrochloric acid, acetic acid treatments can be more easily inhibited or retarded for treatments of long duration. This is necessary particularly in applications requiring the protection of exotic alloys or in high-temperature wells. In most cases, acetic acid is used in conjunction with hydrochloric acid and other acid additives.
Industry:Oil & gas
An operation in which the well stream is passed through two or more separators that are arranged in series. The first separator is called first-stage separator, the second separator is called second-stage separator and additional separators are named according to their position in the series. The operating pressures are sequentially reduced, so the highest pressure is found at the first separator and the lowest pressure at the final separator. <br><br>The objective of stage separation is to maximize the hydrocarbon liquid recovery and to provide maximum stabilization to the resultant phases (liquid and gas) leaving the final separator. Stabilization means that considerable amounts of gas or liquid will not evolve from the final liquid and gas phases, respectively, in places such as stock tanks or gas pipelines. Additionally, stage separation reduces the horsepower required by a compressor, since the gas is fed at higher pressures.
Industry:Oil & gas
An operation in which numerous reservoir intervals are hydraulically stimulated in succession. Staged hydraulic fracturing operations are commonly performed from horizontal wellbores placed in shale gas reservoirs. Using geomechanical data, engineers are able to optimize the placement of perforations and fracturing stages to maximize gas production. <br>
Industry:Oil & gas
An operation in which a logging tool is lowered into a borehole and then retrieved from the hole while recording measurements. The term is used in three different ways. First, the term refers to logging operations performed at different times during the drilling of a well. For example, Run 3 would be the third time logs had been recorded in that well. Second, the term refers to the number of times a particular log has been run in the well. Third, the term refers to different runs performed during the same logging operation. For example, resistivity and nuclear logs may be combined in one tool string and recorded during the first run, while acoustic and nuclear magnetic resonance logs may be recorded during the second run.
Industry:Oil & gas
An operating condition during a snubbing operation in which the force resulting from the weight of the pipe or tubing string is greater than the wellhead pressure and the buoyancy forces acting to eject the string from the wellbore. In the heavy-pipe condition, the string will drop into the wellbore if the gripping force is lost.
Industry:Oil & gas
An oilfield installation used when producing from a gas-condensate reservoir. In a cycling plant, the liquids are extracted from the natural gas and then the remaining dry gas is compressed and returned to the producing formation to maintain reservoir pressure. This process increases the ultimate recovery of liquids.
Industry:Oil & gas
An operating condition during a snubbing operation in which the wellhead pressure and buoyancy forces are greater than the force resulting from the weight of the pipe or tubing string. In the light-pipe condition the string will be ejected from the wellbore if the gripping force of the slips is lost.
Industry:Oil & gas
An opening in the top of the stock tank. The thief hatch allows tank access for a thief or other level measuring devices.
Industry:Oil & gas
An opening in the top of a tank through which samples are taken or inspection is made.
