OPEN HOLE FRAC SYSTEM |
摘要 |
A fracturing operation is done in open hole without annular space isolation. The annular space is spanned by tele-scoping members that are located behind isolation valves. A given bank of telescoping members can be uncovered and the tele-scoping members extended to span the annular space and engage the formation in a sealing manner. Pressurized fracturing fluid can be pumped through the telescoped passages and the portion of the desired formation fractured. In a proper formation, cement-ing is not needed to maintain wellbore integrity. The telescoping members can optionally have screens. Normally, the nature of the formation is such that gravel packing is also not required. A production string can be inserted into the string with the telescoping devices and the formation portions of interest can be produced through the selectively exposed telescoping members. |
