WebHis technique involves (1) calculating transmissivity from the time-drawdown data, (2) calculating a measured specific capacity, meas c S , at the end of the time-drawdown test, (3) calculating a theoretical specific capacity, theor c S , from the calculated transmissivity (using eqn. 18), and (4) calculating well efficiency, p L , from the ... WebDec 1, 2024 · Specific capacity is the ratio of pumping rate (Q, L 3 /t) to water-level decline (drawdown = s, L; SC = Q/s). Because SC data are commonly collected during well drilling and recorded on permits or well-completion reports, these data can be cost-effectively obtained by query of well-permitting databases.

Latitude and longitude WebApr 1, 2016 · If we use specific capacity as a limited analogy to well efficiency, we can then redefine development as being “more complete when the specific capacity is no longer increasing relative to the effort put into increasing it.” As stated previously, there is a relationship between the development of efficiency and the time expended to develop it.
WebSpecific capacity is defined as the rate of discharge of a production well per unit drawdown and is calculated by dividing the pumping rate by the change in head for each step (Fetter, 2001). The general term “well efficiency” refers to an operational pumping rate of approximately 60 to 80 percent of specific capacity (Heath, 1983).
