We will ensure that the entire hole is thoroughly logged for geotechnical as well as current and future exploration purposes. Open hole completions were originally used in the early days of the petroleum industry when most wells were drilled with cable tools. Effectively there are tools that record certain properties with the casing, coating the well, logs Geophysical well logging is a mature technology comprising many separate systems. 5 INTRODUCTION HOISTING AND RIGGING PROGRAM Safety should be the first priority when performing lifting operations. In open hole logging, it is used to determine hole volume and aids the engineer in designing a cementing program. In this type of landscape it is common for streams at the surface to disappear into an open sinkhole, flow underground through a cave system, and return to the surface as a spring. • Quick Look Interpretation of Logs. No casing need normally be used, since bentonite mud flush provides wall support. INTRODUCTION. Table 2. A few variables must be taken into account when dealing with stuck pipe: pore pressure of the formation, mud system, and the depth versus time (the longer in the hole without action, the more likely to get stuck). The program director can access this information by logging into the Case Log System with his or her ADS password and program number. With no The Lugeon test, sometimes call also Packer test, is an in-situ testing method widely used to estimate the avarage hydraulic conductivity of rock mass.
