Xxproinvestor, i re-read your last 2 posts, i do not see any questions to answer ?.
However i am happy to answer the question i posed to you and give a link to Schlumberger online doc that describes the parent/child well dilema in better detail, I always feel its better to back up posts with a link or checkable data, don’t you, no I guess you don’t as you never do.
Wingster asked why we dont just drill a well (H3 i guess) adjacent to H1 where we know there is oil, if we did this it would be described as an infill or child well, there can be benefits in doing this but there can also be issues (Schlumberger link explains) basically H1 production rate could fall off (but not guaranteed to) and H3 is unlikely to be as productive as H1, the combined output from H1 and H3 would almost certainly be greater than we would get from H1 alone but the result would almost certainly guarantee a shorter life span for both H1 and H3, simply not possible to state an exact life span but certainly nothing like the 20 to 30 years life span we can expect from H1 just now with no other well near, that said H2 is 800 metres (2600 feet) away from H1, this lies just outside the furthest norm for a child well, normally the limit is accepted as 2500 feet, theoretically (as per my 9.00 am post) we could frack H2 and turn it into an infill/child well of H1, worst case scenario we bleed both wells dry in 5 or 10 years while creating much needed revenue in the very near term and next 5 or 10 years.
As the SLB link below states infill/child wells account for 60% of new wells drilled in North America, if it works there no reason to suspect Mongolia would be different.
