2. Baptist well drilling - Wikipedia

   en.wikipedia.org/wiki/Baptist_well_drilling

   If required, the upper part of the well can be reamed and cased with larger diameter pipe (3 or 5 inches), to accommodate larger pumps. A shallow (large diameter) rope pump, for example, may require a wider well and submersible pumps commonly need at least 4". Note that there is no need to enlarge the entire depth of the borehole: reaming until ...

   A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. [1] Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various ...

   Diagram showing the MWD Negative pulse Negative pulse tools briefly open and close the valve to release mud from inside the drillpipe out to the annulus. This produces a decrease in pressure that can be seen at surface. The digital information can be encoded in the pressure signal using line codes or pulse-position modulation. [9] Continuous wave

6. Wellhead - Wikipedia

   en.wikipedia.org/wiki/Wellhead

   When the well has been drilled, it is completed to provide an interface with the reservoir rock and a tubular conduit for the well fluids. The surface pressure control is provided by a Christmas tree , which is installed on top of the wellhead, with isolation valves and choke equipment to control the flow of well fluids during production.

   This means that they are installed as a component of the completion string and run in during completion. Retrieving the valve, should it malfunction, requires a workover. The full name for this most common type of downhole safety valve is a Tubing Retrievable Surface Controlled Sub-Surface Valve, shortened in completion diagrams to TRSCSSV.

9. Aquifer storage and recovery - Wikipedia

   en.wikipedia.org/wiki/Aquifer_storage_and_recovery

   The first agriculture ASR wells were put into service in Oregon in the autumn of 2006 and have injected well over 3,000 acre-feet (3,700,000 m 3) of water during the winter and spring flood flow times using artificial recharge (AR) of flood water as their water source. This shallow recharged water is then recovered as potable water and injected ...
