Using Machine Learning Methods to Identify Coals from Drilling and Logging-While-Drilling LWD Data
Proceedings of the SPE/AAPG/SEG Asia Pacific Unconventional Resources Technology Conference, 2019Accurate coal identification is critical in coal seam gas (CSG) (also known as coalbed methane or CBM) developments because it determines well completion design and directly affects gas production. Density logging using radioactive source tools is the primary tool for coal identification, adding well trips to condition the hole and additional well ...

Abstract Formation evaluation (FE) while drilling is an established technique in horizontal well orientations for unconventional reservoirs such as the Barnett Shale. Due to constrained well economics, special care is taken to acquire cost-effective information quickly to maximize lateral wellbore effectiveness.

The crucial element in logging that has so far been covered up, is the wellbore and the drilling process that creates it. Although it is beyond the scope of this volume to discuss drilling, there are several aspects that merit mention in their relationship to logging.

Proceedings of SPE/IADC Asia Pacific Drilling Technology, 1996
Abstract Although at-bit measurements provide rapid detection of changing lithology, real-time logging-while-drilling (LWD) services are helpful in steering a horizontal well through the pay zone. Furthermore, these services provide the petrophysical data for formation evaluation. As the picture becomes more complex,

Abstract An operator in Asia Pacific required a large sample volume from a gas reservoir for accurate non-hydrocarbon gas (NHCG) content analysis from two extended reach wells. This extended abstract highlights the use of an LWD fluid sampling and formation pressure-testing device to overcome numerous challenges,

Sonic dipole shear anisotropy orientation in subsurface formations is key information for a complete characterization of rock mechanical models for well planning. In Wireline logging, it is estimated with the well-known Alford rotation on four-component inline and crossline waveforms from two orthogonal dipole firings.

The Benefits of Logging While Drilling (LWD) for Formation Evaluation in the Dulang West Field
SPE Reservoir Evaluation & Engineering, 1998Summary Ever since the first electric log was run in 1927, the oil industry relied on wireline-conveyed logging for the acquisition of formation data for petrophysical analysis. It was not until 1978 that the first measurement while drilling (MWD) tools were introduced in the field.
