Evaluation Parameters

We applied a mud pulse signal to transmit the downhole measured parameters in a Logging While Drilling (LWD) system. The high-data-rate mud pulse signal was almost completely overwhelmed by noise and difficult to be identified because of the narrow pulse width, impacts of the pump noise, and the reflected wave. The wavelet transform’s multiresolution is suitable for signal denoising. In this paper, during the denoising process of the wavelet transform, we used a series of evaluation parameters to select the optimal parameter combination for denoising a mud pulse signal. We verified the feasibility of the wavelet transform denoising algorithm by analysing and processing an operational high-data-rate mud pulse signal. The decoding algorithm was available by applying self-correlation and bit synchronization. The application results through a field application showed that the processing algorithm was suitable for the high-data-rate mud pulse signal’s process.

Effectiveness And Efficiency

10,000 ft horizontal drilling and hydraulic fracturing with 24 to 36 stages are prominent in Bakken petroleum system with great success. Although advanced automated drilling system with cutting edge comprehensive logging units are available from service providers to obtain various data assisting comprehensive real-time analysis, conventional positive displacement motor (PDM) with mud-pulse (MP) measurement while drilling (MWD)/logging while drilling (LWD) system is still widely applied in this area to steer and navigate the well bore in pay zone with cost-effectiveness and efficiency. In this paper, several field cases for MP MWD/LWD systems will be discussed and lessons will be summarized to help optimize rate of penetration (ROP), reduce non-productive rig time, and improve operators drilling practices.
