When we see reservoirs of water, we can imagine dropping a giant straw into the middle and sucking up the entire lake.

What theyвЂ™re unlikely to do is pinpoint the exact place where theyвЂ™d access the maximum amount of resources.

Their estimates are based on different types of surveys, and past experience. People who perform well plans such as seismic geologists, geoscientists, exploration engineers and CAD experts join together to give the best idea of where oil and gas deposits may lie. Scientific terms give a label to help everyone understand each other, but Mother Nature has different ideas about the way she organises things. Geologists and engineers use terms such as an вЂoil reservoirвЂ™ or a вЂhydrocarbon reservoirвЂ™ to describe underground pockets of resources. Rigs and crews have day rates that run into the hundreds of thousands of dollars, one rig working up to five or ten square miles is very cost-effective in comparison to having a dozen or more vertical rigs, which may or may not be tapping into the same accessible reservoir deposits.

In an oilfield with dispersed deposits, a large radius can be tapped, maximising the expensive asset which is the rig. Also, these boreholes can extend up to a mile down, and for more than five miles at shallower angles. Multiple down holes can be drilled from the same rig, minimising surface disturbance and environmental impact. Even the branches of the roots are comparable to multilateral drilling. If we imagine the rig as the trunk of the tree, the directional possibilities of the roots are endless. Students of petroleum engineering often get shown illustrations and diagrams that look like tree roots. ItвЂ™s possible for ERD specialists to drill for more than 10 kilometers/6.2 miles. Techniques such as multilateral, horizontal and extended reach drilling (ERD) are enhanced oil recovery (EOR) methods that can increase the yield of a downhole dramatically. Over the past few decades, technological improvements have meant that angles, turns and underground distances covered are amazing feats of engineering.

Nowadays, however, itвЂ™s more likely that thereвЂ™ll be a series of one or more carefully planned directional changes along the wellbore.Дirectional drilling techniques have been employed for almost 100 years now. If a driller aims away from the 180-degrees down, thatвЂ™s technically directional drilling. In conventional drilling for oil and gas, the drill bit, drillstring, pipe and casing all go down in a straight line. In this instance, the driller uses sidetracking techniques. In fact, even in a vertical well, it might be necessary to deviate to avoid a geological formation or a previous stuck pipe, then return to the original path. Guys that don't have the most advanced equipment still have over $1 million in equipment that they tote around to every site they go to on a daily basis, you don't recover that kind of investment by charging $100 for a job that takes at least 1-2 hours just to show up, set up and take down, even though the actual boring itself only took 5 minutes or less.Directional drilling is a broad term used to describe any boring that doesnвЂ™t go in a straight line vertically down. Be prepared for at least $100 just to show up, but depending on what they drag with them for equipment and crew - you may expect at least $500 in many cases.

Professional boring contractor will charge you more to show up then it will cost to do the short distances you are requesting.

I've pushed 2' PVC about 30-40 feet under a railway in sandy soil with this method before, most other times has usually been smaller raceway and/or shorter distances. You need to use some judgement on what you may encounter should you bore it yourself, depending on soil type and no further then you need to go connecting a water hose to a piece of conduit and 'washing' it under the sidewalk works fairly well as long as there is no obstruction to hit.
