... Abstract Maximum reservoir contact and extended reach wells have been widely used to maximize the well productivity. The horizontal section could be 6000 ft or more in those wells, which make the damage caused by the drilling fluid varied from one section to another in the long horizontal...

... for assuring effective reservoir drainage and delaying the arrival of water breakthroughs. The idea is to provide a variable distribution of area open to flow along the horizontal section. The technique is applicable for several situations and is even more attractive in long horizontal section wells in heavy...

... above the bubble point. Even so, the test data in association with reservoir simulation, according with the field geology, showed that there was fluid injection throughout the entire horizontal section. Therefore, it was decided to perform a mud acid treatment, again, using the pulse-rotating jet tool...

... per well. The last 5 horizontal wells were put on stream at a more than of 8000bbl /day flow rate. To achieve maximum productivity from the horizontal drains, complete entry exposure had to be established along the entire length of the horizontal section. To meet this objective the perforated...
