In the early phase the beginning of the development of horizontal well technology, the length of a horizontal. wellbore could be drilled no longer than a few hundred meters. The longer the horizontal wellbore is drilled, the. more oil is extracted.

This protection effort is made up of many different aspects. and each one has been addressed within this booklet. This guidelines handbook is not intende d to be a step-by-step procedure. manual, but rather a collection of fundamental elements of the HDD. process.

K:\Library\APWA_Accreditation_Library\Chapter_14_Right-Of-Way_Management\14.8_Pavement_Cut_Restoration/HDD Guidelines.docx. Introduction. This Handbook is intended to be used as a basic guide for Horizontal. Directional Drilling (HDD) applications performed within the City of. Overland Park. The overall purpose is to provide guidelines that will. help ensure public safety and protection of existing underground. facilities.

In this way, the curve between the horizontal wellbore length L and the NPV. of the horizontal well can be drawn as Figure 2.The curve of NPV—L is quite similar to the curve of NPV—C(the. relationship between NPV and the capital invested in a project )⑦, the only difference is the horizontal axis.

Currently, with the development of horizontal well drilling technology, the horizontal wellbore length can be drilled longer than the exact prescribed length, which means there is a need. to optimize the horizontal wellbore length in order to get more economic efficiency.

Depending on the light rig size the number of loads ranges from 3 to 7. The typical spread sets up on a footprint of 10m wide by 30m long. This includes the drilling rig, support truck, drill stem trailer, and water truck. With adequate access for large trucks, the rig can be set up and ready to drill in under an hour.

If the horizontal wellbore keeps on being drilled to the point F, where the NPV of the horizontal. well itself gets the maximum value, the length of the horizontal at the point F is not the optimum length but the. upper. limit, i.e., the maximum length.

When using horizontal directional drilling (HDD) technology in a pipeline crossing project, the required pullback force is an important factor in the selection of the pipe strength and drilling equipment, as well as the construction technique.. There are presently several methods used to calculate this force.

Production rates vary based on the geological formation and size of the product line. It is reasonable to setup, drill and pull in 400m of pipe in one 12 hour shift. The Crossing Company LRD has successfully completed reams as large as 1067 mm (42) in diameter and lengths up to 900m.

maximum distance for horizontal drilling
A maximum distance for horizontal drilling is a few hundred meters. The maximum distance for horizontal drilling is no longer than a few hundred meters.
