With deepwater drilling rig rates in 2015 of around $520,000/day, [25] and similar additional spread costs, a deepwater well of a duration of 100 days can cost around US$100 million. [ 26 ] With high-performance jackup rig rates in 2015 of around $177,000, [ 25 ] and similar service costs, a high pressure, high-temperature well of duration 100 ...
The Bakken is a notoriously tough area for producers to drill, which is why the play has some of the highest well completion costs in the U.S. Producers can spend $10 million or more to drill a ...
The concept coincided with development of directional drilling techniques that allowed companies to drill horizontal wells accurately, cheaply and efficiently, to the point that it became hard to justify drilling a conventional vertical well any more. With the low cost of drilling horizontal well pairs, and the very high recovery rates of the ...
But the cost to drill a new well is about $45 to $65 a barrel, he said. Because the company wants to cover its costs and make about a 15% profit, “if prices got any lower, we would stop ...
The planning phases involved in drilling an oil or gas well typically involve estimating the value of sought reserves, estimating the costs to access reserves, acquiring property by a mineral lease, a geological survey, a well bore plan, and a layout of the type of equipment required to reach the depth of the well. Drilling engineers are in ...
