Borehole Sonic Data Dispersion Analysis With a Modified Diﬀerential-Phase Semblance Method
Authors:   Halliburton, Wang Ruijia , Coates Richard ,   Previously Halliburton, Zhao Jiajun ,   Halliburton
Published: July 2021

Ruijia Wang, Richard Coates, and Jiajun Zhao The sonic wave fields produced by wireline and logging-while-drilling (LWD) monopole, dipole, and quadrupole tools often consist of multiple borehole modes. Classic frequency-slowness semblance-map methods used to process this data often detect only strongly excited modes and overlook weak ones, and erroneously detect some modes. Conventional dispersion processing methods can be separated into two groups: single-mode and multimode extraction algorithms. Single-mode methods are stable but only return one mode, the most energetic one, at each frequency. Single-mode methods include the differential-phase frequency-semblance (DPFS) method and the weighted spectral-semblance method. Multimode methods can return multiple modes at each frequency but may be unstable in some cases. Due to their assumptions about signal models, multimode methods are often sensitive to unbalanced receiver arrays, poor data quality, and formation heterogeneity. For example, in some extreme cases, such as a formation with strong heterogeneity, multimode methods may yield erroneous ghost modes or discontinuous dispersion curves for each mode. Borehole modes with different slowness have different arrival times. Converting the data to the frequency domain can obscure this critical information or encode these time differences into phase differences between adjacent frequencies. Conventional frequency-semblance approaches, which use only a single frequency independently from adjacent ones, ignore this phase information. In this paper, we propose employing the phase differences between adjacent frequencies to facilitate multimode dispersion analysis. We modify one conventional method to incorporate the arrival time of modes or the phase difference between adjacent frequencies. We validate the proposed approach with synthetic, laboratory, and field data. The results suggest the method can extract a much more comprehensive representation of modes present in the sonic data. Additionally, the method provides reliable estimates, even when the number of receivers is small. Unlike the Prony and matrix-pencil methods based on assumed signal models, the proposed approach, which we denote “Modified Differential-Phase Frequency Semblance” (MDPFS), is a modification of the single-mode differential phase approach. The MDPFS is still a semblance-based approach, and as with other semblance-based processing, it is expected to be less sensitive to unbalanced receiver arrays, poor data quality, and formation heterogeneity than other multimode algorithms.

A saturation evaluation model suitable for Nanpu volcanic rock formation is established based on the experiment of acoustic velocity changing with saturation during the water drainage process of volcanic rock in the Nanpu area. The experimental data show that in the early stage of water drainage, the fluid distribution in the pores of rock samples satisfies the patchy formula. With the decrease of the sample saturation, the fluid distribution in the pores is more similar to the uniform fluid distribution model. In this paper, combined with the Gassmann-Brie and patchy formula, the calculation equation of Gassmann-Brie-Patchy (G-B-P) saturation is established, and the effect of contact softening is considered. The model can be used to calculate water saturation based on acoustic velocity, which provides a new idea for the quantitative evaluation of volcanic oil and gas reservoirs using seismic and acoustic logging data.

To improve the learning quality of SMK students in the accounting field, various breakthroughs are needed, both in curriculum development, learning innovation, learning media and fulfillment of educational facilities and infrastructure. The use of computers in the learning process is inevitable in today's digital era. The need for computers is increasing rapidly in any field of science, including the field of accounting. Computers can be very helpful in all accounting work which is usually done manually. This can be realized with the help of accounting software, one of which is MYOB Accounting. Today, many students are not very familiar with MYOB as a software that is able to complete work in the accounting field. Students also do not know exactly how to use it. Accounting always contains a count of numbers that are often very large, so they can provide a high error rate when done manually. To find alternative solutions to the problems above, a training on the introduction of MYOB and its benefits in accounting was held. With the aim of training students of SMK 2 BM Swasta Medan Putri to be able to use MYOB and apply it in the accounting field.

Selanjutnya data disimpan dalam media penyimpan berupa SD/MMC card yang dapat diunduh dan dianalisa lebih lanjut menggunakan personal computer, sehingga dapat diketahui nilai energi listrik. Dari percobaan yang dilakukan, ternyata data logger dapat bekerja dengan cukup baik. Dari hasil pencatatan didapatkan bahwa nilai tegangan mempunyai penyimpangannya 4.49 %, sedang untuk nilai arus listrik penyimpangannya 2.45 %. Nilai tegangan yang didapatkan relatif besar bila dibandingkan dengan pengukuran dengan menggunakan peralatan ukur yang presisi, Besarnya kesalahan ini antara lain disebabkan penggunaan komponen resistor pembagi tegangan yang memiliki toleransi yang besar. Dengan menggunakan resistor metal film yang mempunyai toleransi lebih kecil, nilai tegangan yang didapatkan akan lebih presisi.Kata kunci : data logger, microcontroller, listrik tenaga surya
