The most common feature of all of these … Nettet1. jan. 1991 · *for a 2000 ft long well, As we see, two methods give different answers for drainage areas. If we take average areas using two methods, a 1000 ft well would drain 71 acres and a 2,000 ft well would drain 101 acres. Thus, a 400 acre field can be drained by 10 vertical wells; 6, 1.000 ft long wells; or 4,2,000 ft long wells. Thus, horizontal ...

He has been … NettetIn Method 2, if we assume that the horizontal well drainage area is an ellipse in a horizontal plane, then for a 1,000 ft long well: a = half major axis of an ellipse = (L/2) + rev =...
Nettet7. mar. 2024 · Most horizontal well models assume that horizontal wells are perfectly horizontal and are parallel to the top and bottom boundaries of the reservoir. In general, the drilled horizontal wellbores are rarely horizontal, with many variations in the vertical plane along the well length, affecting pressure gauge inserted at the producing end of … Nettet5. des. 2024 · The drainage area of the horizontal well along the well bore is elliptical, and the well is perforated in different segments. Therefore, the real drainage area of horizontal well is a series of ellipses along the well bore. For simplification, the drainage area of a horizontal well along the well hole is taken as A, where, A = 2 LRe.

Therefore, if the horizontal well is to be stimulated, it is important to consider the local directions (Joshi, 1990). Horizontal well drainage area is one of the important variables needed to be determined in the production forecast of horizontal wells. By knowing the drainage area, we can determine the wells spacing
