This workshop provides a comprehensive overview of the design process, emphasizing the working stress approach currently used in the industry. Upon completion, participants will be able to select casing points, identify tubular requirements, loads, and present a design which incorporates life cycle considerations. Estimation of standard and special loads is covered in detail. Horizontal oil and gas well drilling has become one of the most valuable technologies ever introduced in the business.
Unlike a directional well that is drilled to position a reservoir entry point, a horizontal well is commonly defined as any well in which the lower part of the well bore parallels the oil zone. Cost experts have agreed that horizontal wells have become a preferred method of recovering oil and gas from reservoirs in which these fluids occupy strata that are horizontal, or nearly so, because they offer greater contact area with the productive layer than vertical wells. To give an idea of the effectiveness of horizontal drilling, the U. The production ratio for horizontal wells versus vertical wells is 3. 2 to 1, while the cost ratio of horizontal versus vertical wells is only 2 to 1. Horizontal oil drilling can be used in many situations where conventional drilling is either impossible or cost prohibitive. This is by no means an exhaustive list, but it should get you thinking about the possibilities of horizontal directional drilling.

Some sources claim that from the 9th century, oil fields were exploited in the area around modern Baku, Azerbaijan, to produce naphtha for the petroleum industry. In 1848, the first modern oil well was drilled on the Absheron Peninsula north-east of Baku, by Russian engineer F. In North America, the first commercial oil well entered operation in Oil Springs, Ontario in 1858, while the first offshore oil well was drilled in 1896 at the Summerland Oil Field on the California Coast. The earliest oil wells in modern times were drilled percussively, by repeatedly raising and dropping a cable tool into the earth.
In the 20th century, cable tools were largely replaced with rotary drilling, which could drill boreholes to much greater depths and in less time. Until the 1970s, most oil wells were vertical, although lithological and mechanical imperfections cause most wells to deviate at least slightly from true vertical. However, modern directional drilling technologies allow for strongly deviated wells which can, given sufficient depth and with the proper tools, actually become horizontal. Before a well is drilled, a geologic target is identified by a geologist or geophysicist to meet the objectives of the well. For a production well, the target is picked to optimize production from the well and manage reservoir drainage.
