The word(s) "well" appears 261 time(s) in 247 verse(s) in Quran in Abdullah Yusuf Ali translation.

(131) Then were they confounded with shame: (they said), "Thou knowest full well that these (idols) do not speak!"

(132) Not the slightest sound will they hear of Hell: what their souls desired, in that will they dwell.

(133) O mankind! if ye have a doubt about the Resurrection, (consider) that We created you out of dust, then out of sperm, then out of a leech-like clot, then out of a morsel of flesh, partly formed and partly unformed, in order that We may manifest (our power) to you; and We cause whom We will to rest in the wombs for an appointed term, then do We bring you out as babes, then (foster you) that ye may reach your age of full strength; and some of you are called to die, and some are sent back to the feeblest old age, so that they know nothing after having known (much), and (further), thou seest the earth barren and lifeless, but when We pour down rain on it, it is stirred (to life), it swells, and it puts forth every kind of beautiful growth (in pairs).

(134) There are among men some who serve Allah, as it were, on the verge: if good befalls them, they are, therewith, well content; but if a trial comes to them, they turn on their faces: they lose both this world and the Hereafter: that is loss for all to see!

(135) With it will be scalded what is within their bodies, as well as (their) skins.

(136) As to those who have rejected (Allah), and would keep back (men) from the Way of Allah, and from the Sacred Mosque, which We have made (open) to (all) men - equal is the dweller there and the visitor from the country - and any whose purpose therein is profanity or wrong-doing - them will We cause to taste of a most Grievous Penalty.

(137) How many populations have We destroyed, which were given to wrong-doing? They tumbled down on their roofs. And how many wells are lying idle and neglected, and castles lofty and well-built?

(138) Verily He will admit them to a place with which they shall be well pleased: for Allah is All-Knowing, Most Forbearing.

(139) Seest thou not that Allah sends down rain from the sky, and forthwith the earth becomes clothed with green? for Allah is He Who understands the finest mysteries, and is well-acquainted (with them).

(140) Who will inherit Paradise: they will dwell therein (for ever).
