Introduction to Directional and Horizontal Drilling - Jim Short

Drill Control is the ultimate solution for Contractors, Engineering offices and Utility companies who deal with Horizontal Directional Drilling and comes in two modules: Design Introduction to directional and horizontal drilling. Tulsa, Okla : PennWell Books. MLA Citation. Short, J. Directional Drilling Specialists Trenchless Technology is now recognised as being one of the most efficient methods for installing pipes and ducts. It is both cost effective and environmentally friendly, causing little or no disruption to the landscape or local environment. Download books for free.

Directional boring , also referred to as horizontal directional drilling HDD , is a minimal impact trenchless method of installing underground utilities such as pipe, conduit , or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig. The technique is routinely used when conventional trenching or excavating is not practical or when minimal surface disturbance is required. Although often used interchangeably, the terms directional boring and horizontal directional drilling are distinct in that they convey a different sense of scale. Directional boring and HDD are similar in some respects to directional drilling associated with the oil industry, however, an equal comparison cannot be drawn as the procedures serve markedly different functions. First, a small diameter pilot hole is drilled along a directional path from one surface point to another. Next, the bore created during pilot hole drilling is enlarged to a diameter that will facilitate installation of the desired pipeline. Lastly, the pipeline is pulled into the enlarged hole, thus creating a continuous segment of pipe underground exposed only at the two initial endpoints.

We apologize for the inconvenience...

At one time, it was assumed all oil wells were essentially vertical or the bottom of the hole was directly under the drilling rig. The petroleum industry did not become fully aware of deviated well problems until the development of the Seminole, Oklahoma field. The wells in this field were drilled very close together and as a result wells were drilling into one another, and ones which were already producing.

Introduction To Directional And Horizontal Drilling

In the past decades, horizontal directional drilling HDD has been successfully used to install various pipelines in different strata. However, construction accidents such as drill-burying and drill-sticking occur occasionally when pipelines installed by HDD method in an unstable stratum such as sand cobble stratum.

Сидя рядом с великим Тревором Стратмором, она невольно почувствовала, что страхи ее покинули. Переделать Цифровую крепость - это шанс войти в историю, принеся громадную пользу стране, и Стратмору без ее помощи не обойтись. Хоть и не очень охотно, она все же улыбнулась: - Что будем делать. Стратмор просиял и, протянув руку, коснулся ее плеча. - Спасибо.

Когда она оглянулась, Дэвид Беккер лежал на полу, прижимая ладони к лицу и корчась от нестерпимого жжения в глазах.

Веспа шла с предельной скоростью. Прикинув, что такси развивает миль восемьдесят - чуть ли не вдвое больше его скорости, - он сосредоточил все внимание на трех ангарах впереди. Средний.

Это не лишено смысла. Джабба сразу понял, что Сьюзан права.

 - Что еще мне остается? - Он представил Хейла на скамье подсудимых, вываливающего все, что ему известно о Цифровой крепости.  - Весь мой план рухнет. Должен быть какой-то другой выход. - Решайте! - крикнул Хейл и потащил Сьюзан к лестнице. Стратмор его не слушал.
