Underground Source of Drinking Water

Underground Source of Drinking Water

Definition(s)

Underground Source of Drinking Water (USDW)

An aquifer or its portion which supplies any public water supply system or currently supplies drinking water for human consumption or which contains sufficient water to supply a public water system or has a total dissolved solids (TDS) concentration of less than 10,000 mg/l. The EPA may exempt an aquifer if it will not serve as a source of drinking water in the future because it is economically or technically impractical to recover the water or to render it fit for human consumption or because the aquifer produces or is expected to commercially produce minerals, hydrocarbons, or geothermal energy. While the EPA defines a USDW as containing less than 10,000 mg/l TDS, certain states, such as California and Texas, have adopted a producing and injection well surface pipe protection standard for fresh water aquifers that contain less than 3,000 mg/l TDS.

Mud

Mud

Definition(s)

Mud

The weighted liquid circulated through the wellbore during rotary drilling and workover operations. In addition to its function of bringing cuttings to the surface, drilling mud cools and lubricates the bit and drill stem, protects against blowouts by holding back subsurface pressures, and deposits a mud cake on the wall of the borehole to prevent loss of fluids into the formation. Originally a suspension of clays in water, the mud used in modem drilling is often a more complex mixture of liquids, reactive solids, or oil, often containing one or more conditioners. Water base mud made from oil field brine may also be used as a well control fluid in plugging operations. Also known as drilling fluid or drilling mud.

Temporarily Abandoned Well

Temporarily Abandoned Well

Definition(s)

Temporarily Abandoned Well

An inactive well should be classified as TA when the completion interval is isolated. The completion interval may be isolated using the bridge plug method, the cement squeeze method, or the balanced cement plug method. As an alternative to the bridge plug method, isolation of the completion interval may also be achieved by installing a plug in an existing packer which does not have tubing. Temporary abandonment should be used when an operator is holding a wellbore in anticipation of future utilization, such as in an enhanced oil recovery project. TA status should begin the day afìer the completion interval has been isolated from the wellbore.

Temporarily Abandoned (TA)

Inactive wells in which the completion interval has been isolated from the interior of the casing. The completion interval may be isolated using the bridge plug method, the cement squeeze method or the balanced cernent plug method. If a packer is installed in the well, isolation of the completion interval may also be achieved by installing a plug in the packer which has no tubing. Temporary abandonment is generally used when a well is a candidate for future utilization, such as in a possible enhanced oil recovery project. TA status should begin the day after the completion interval has been isolated from the wellbore.

Shut-In Well

Well with one or more valve(s) closed on the flow path. Source: ISO 16530-1:2017, Petroleum and natural gas industries — Well integrity – Part 1: Life cycle governance, First Edition, March 2017. Global Standards

Shut-In Well

An inactive well should be classified as shut-in when the completion interval is open to the tubing or to the casing. A shut-in well may have tubing and packer, which isolates the interior of the casing above the packer from the completion interval. A well may also be shut-in without a packer which exposes the interior of the casing to any fluids from the completion interval. Shut-in wells may have been removed from active service in anticipation of workover, temporary abandonment, or plugging and abandonment operations. Generally, the wellbore condition is such that its utility may be restored by opening valves or by energizing equipment involved in operating the well. Shut-in status should begin three months after production, injection, disposal, or workover operations cease.

Shut-In

Inactive wells in which the completion interval is open to the tubing and to the casing, or is open to the tubing only. The well may be shut-in without packer and with or without tubing, in which case the interior of the casing is not isolated from the completion interval. Or, the shut-in well may have tubing and packer, which isolates the interior of the casing above the packer from the completion interval. Shut-in wells have been removed from active service in anticipation of a workover, temporary abandonment, or plugging and abandonment operations. Generally, the wellbore condition is such that its utility may be restored by opening valves or by energizing equipment involved in operating the well. Shut-in status should begin 90 days after production, injection, disposal or workover operations cease.

Inactive

Inactive

Definition(s)

Inactive

The term inactive, when used with regard to well status, is broadly defined by regulatory agencies and covers a wide spectrum of wellbore conditions. Furthermore, Federal and state regulatory programs rarely make a distinction between inactive wells which have the completion interval isolated from the wellbore and those which have open completion intervals. Well status terms such as shut-in, standing, temporarily abandoned (TA), inactive, suspended, etc. have generally been used interchangeably by regulatory agencies. Industry and regulatory agencies should standardize the terminology used to describe inactive wells. API recommends that inactive wells be classified as either shut-in or TA as defined below.
