Wireline Logging Operations Pdf Drilling Rig Nature The first objective of logging in an exploration area is to locate hydrocarbons in a well. next, the operating company wants to determine if enough resource is present to economically justify completing and producing the well. Wireline is commonly used to perform various well logging operations to find more information about the wellbore and surrounding formation. some examples of the formation characteristics that can be determined with the help of logs are rock type, porosity, fluid types, and pay zone size.
Safety Protocols For Wireline Logging Operations A Job Safety Analysis Wireline logging can be done when the newly drilled rock formations form the wall of the borehole (open hole logs) or after a concrete lining or casing has been inserted to stabilize the well bore (cased hole logs). Wireline logs are then combined with the drilling data, mud logs, measurements while drilling and core information in order to choose correct testing and completion intervals and to properly evaluate the production potential of the well. a good evaluation is only possible with good quality log data. This document is intended to provide the reader with guidelines for planning a logging job, witnessing logging operations and the basic evaluation skills needed to address some of the more common north sea data gathering objectives. Wireline logging offshore provides high resolution formation and well integrity data to guide immediate operational decisions (casing points, testing, completions) and long term field.

Wireline logging offshore provides high resolution formation and well integrity data to guide immediate operational decisions (casing points, testing, completions) and long term field. Logging operations shall commence when the hole conditions are stable. a check trip shall be required before running the formation pressure sampling tool if there were hole problems during the previous run. Fig. 4.1 shows a typical setup for a logging job. a logging truck is anchored about 100 to 200 ft from the well. two sheaves are mounted in the derrick with one suspended from the crown block and the other chained down near the rotary table. Wireline logging procedures – step by step instructions for running cased hole logging tools, conducting caliper logs, and verifying cement bond logs (cbl log). Disciplined planning and stellar execution is essential in wireline logging operations to produce reliable data that empowers you to reach every business goal on time and on budget—all while maintaining optimal safety conditions.
