OpenStreetMap
Two major achievements today - adding the DECC's (source=DECC) entire list of UK oil wells (they confirmed it was public domain data yesterday morning), and mapping the park next to my house.
There are now 11,015 disused oil wells in the OSM database around the UK and a further 500 active ones. Unfortunately there is no official tag and they won't show up on the map, but the data is there (man_made=petroleum_well) for anybody interested. They have other data too, but it doesn't appear to be of much use for us.
I'd put off mapping the park by my house for so long because of its complicated pathways, and the sheer number of different tags it has (maze, bowling greens, play area, band stand, gardens, etc.) many of which were new to me. It's still not entirely correct, but good enough (the major pathways and features are all in, if not entirely accurate). Unfortunately the name of the park is rendered directly over the tiny bandstand in Mapnik. I have filed a bug report for this to be fixed, but I don't know how easy a fix it is.
A lesser achievement was taking my new bike out for a spin yesterday. It's a joy to ride, not terribly fast but nice low gears for getting up the Bradford hills. I'm hoping to have a chance for a decent length ride this weekend.

Is there an area that is particularly interesting? E.g. has a high concentration of wells, or shows all the examples (onshore/offshore, active/disused) near each other.
Someone could whip out icons and a render of wells (e.g. Kosmos). Even if they don't host the full UK online, it would make a good 'featured image' on the wiki and the stylesheet could be made available for others to use.

Try Duke's Wood, Nottinghamshire (map). This was Britain's first on-shore oil-field and is now a Nature Reserve, but with one or two old donkey pumps preserved. The road layer on GoogleEarth shows lots of tracks in this location, presumably the former access roads to the wells. I'm not sure how many are really extant on the ground. Not completely sure how accurate the data is either: the 4 wells here are all shown S of Pudding Poke Wood (check on NPE), whereas the NWT map of Pudding Poke/Duke's Wood shows 5 wells still in situ. I can certainly remember seeing 3 a couple of years ago.

I have two screenshots from Josm to give an idea of where they all are but they only show as unrecognised node types. Current oil wells and Disused oil wells
The DECC were keen to state that they hold no responsibility for any errors or omissions, so they may be aware that this dataset is less than perfect and aren't willing to say so directly.
