Features of Logging While Drilling in Horizontal Wells to Estimate Reservoir Properties

Authors: Maria A. SREBRODOLSKAYA graduated from Gubkin Russian State University of Oil and Gas (National Research University) in 2013 with Master Degree in Petroleum Engineering with honors. She is Candidate is Ph.D student in geology and mineralogy. Her research scope is petrophysics, log data processing in complicated reservoirs, well logging in horizontal wells. She is author of more than 40 scientific publications. E-mail: mary_roza@bk.ru

Abstract: The features of logging while drilling (LWD) in horizontal wells are considered. When logging while drilling, geophysical tools are incorporated in the bottom-hole assembly (BHA) above the bit. The composition of the BHA when drilling horizontal wells and offsets of sensors depending on the drilling method (RSS or DDM) are considered. Features of image data recording in horizontal wells with azimuthal tools are described. The factors influencing the BHA composition are analyzed, some of them being: the tasks to be solved, the drilling method, the well design and technical conditions in it, the presence or absence of geosteering service. The environment (lithological conditions) influencing the LWD complex is shown. The limitations imposed on the LWD complex are listed. Various information channels and peculiarities of data transmission in real time mode are considered. It is shown that both information channels transmitting data to the surface and autonomous channels for recording data limit the volume of the logging while drilling complex

Abstract: Bazhen Formation cyclic structure is explained and mineral composition heterogeneity of these deposits is characterized. Histograms of distribution of main rocks components weights incl. kerogen, kerogen volume, coefficients of total and open porosity in sedimentation cycles are analyzed. The regularities of the organic material (kerogen) distribution are considered in detail, depending on the sedimentation cycle and carbonate material concentration. Histograms of distribution of gamma-ray index in Salym oilfield wells in sedimentation cycles are described. The features of the lithological structure and mineral composition of each of the three cycles are identified and described. The conclusions about the advisability of creating a differentiated approach to Bazhen Formation sediments interpretation model are made in order to reduce errors in determining the total porosity values

Abstract: Companies have been displaying growing interest in formulating quantitative assessment of the efficiency of investment in human resources. HR specialists want to show how training and development affect the company’s performance. This allows, on the one hand, to assert the costs of training, and on the other hand, to show the importance of investment in the personnel for the company’s strategic production and business development. Managers are currently in need of a tool to analyze situations and make predictions on how investing in the personnel affects the company’s final performance. This article focuses on the formation and implementation of the quantitative indicators system to measure human capital assets as applied to the enterprises of the Russian oil and gas industry.
