Is horizontal drilling better?
Drilling horizontally, parallel to the geologic layers in tight formations, allows producers to access more of the oil- and natural gas-bearing rock than drilling vertically. The lateral length of horizontal wells has also increased, allowing for more exposure to oil- and natural gas-producing rock from a single well.
Is horizontal drilling expensive?
Horizontal drilling is expensive. When combined with hydraulic fracturing, a well can cost up to three times as much per foot as drilling a vertical well. The extra cost is usually recovered by increased production from the well. These methods can multiply the yield of natural gas or oil from a well.
How much does horizontal directional drilling cost?
3.1 Construction Cost
|Directional Boring – Rural||$6.00||$7.00|
|Directional Boring – Urban||$8.00||$10.00|
|Directional Boring – Rock||$42.50||$271.00|
|Conduit (2” HDPE)||$0.75||$0.80|
What is the purpose of horizontal drilling?
Horizontal drilling is a commonly used technology because drilling at an angle other than vertically can stimulate reservoirs and obtain information that cannot be done by drilling vertically. Horizontal drilling can increase the contact between the reservoir and the wellbore.
How far can you horizontally bore?
Maximum lengths and hole diameters are determined by project specific geotechnical conditions however effective outside range for heavy rig horizontal directional drilling is 3,000 m (9,843′). Light rigs are typically used for crossings between 50 m and 1,000 m (164′ – 3,281′).

How do drilling rigs drill horizontally?
Horizontal drilling is the process of drilling a well from the surface to a subsurface location just above the target oil or gas reservoir called the “kickoff point”, then deviating the well bore from the vertical plane around a curve to intersect the reservoir at the “entry point” with a near-horizontal inclination.
How far can you directional bore?
These technologies are capable of reaching 10,000–15,000 ft (3000–4500 m) and may reach 25,000 ft (7500 m) when used under favorable conditions.
What are the regulatory systems for horizontal drilling?
Specifically, this article dis- cusses the regulatory systems pertain- ing to spacing, density and proration rules, with special attention to recent developments in the regulation of horizontal drilling.
What are the rules for multiple drainholes in a well?
Rule 86 specifically allows drilling of multiple drainholes from a single surface location, known as “multilateral” wells, and treats them as a single well for permitting purposes.48However, many special field rules also allow “stacked laterals,” which are multiple drainholes
What are the rules for Verti-Cal well spacing?
However, special field rules for some verti- cal wells prescribe a “diagonal” rule, which usually requires that the length of the unit not exceed twice the width in order to prevent formation of long, awkwardly shaped units.15 Winter 2013-14 37 Landman O & G REL A T I G U O N S I NTE X A S
What does proration mean in oil and gas drilling?
Proration regulates the volume of oil or gas that may be produced from a completed well, known as an “allow- able.” A “proration unit” is the productive acreage assigned to a well to obtain an allowable and is typically the same size and shape as the well’s drilling unit.10
