Available in PDF, EPUB and Kindle. Book excerpt: Horizontal Directional Drilling (HDD) is a growing method for installation of pipes in urban areas and where trenching is impossible or undesirable; such as in crossing rivers, lakes, railways, and special areas such as airports. This technique utilizes downhole cutting heads to create a pilot borehole before it is enlarged with back reamers to allow pulling back of a product pipe. The utilization of HDD for the installation of underground infrastructure (i.e., water, wastewater, oil and gas pipes, telecommunication, and power conduits), has shown a rapid growth compared to other trenchless technologies. HDD can install a range of pipe diameters from 2 to 60 inches utilizing different pipe materials including steel, high density polyethylene (HDPE), polyvinyl chloride (PVC), and ductile iron pipe (DIP) with minimum surface and daily life disruptions. Estimation of HDD productivity, project duration, and quantity of materials required, is a difficult task due to variable productivity conditions such soil, project, contractor, and machine conditions involved in operation. The objectives of this research are to define the significant subconditions that affect HDD productivity by utilizing the analysis of variance (ANOVA) model, to develop HDD productivity prediction model, and to develop HDD user interface as a planning tool for operation. Initially the main productivity conditions and subconditions were identified through literature review and consulting the HDD experts and professionals. A HDD questionnaire was designed, reviewed, and sent to HDD experts (contractors, design engineers, and consultants) to collect data addressing HDD operation conditions required for testing significance of subconditions and modeling operation productivity. HDD subconditions that show significance by ANOVA model analysis will be used to model HDD productivity in clayey and rocky conditions. This model is applicable in predicting HDD productivity to estimate duration of HDD project, in addition to other project parameters such as quantities of materials required and cost of labor. Applications on HDD productivity model will be useful for consultants and contractors for planning, scheduling, and bidding of HDD projects during preconstruction stage, as well as during installation and construction.

This book was released on 2014 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horizontal Directional Drilling (HDD) is one of the most rapidly growing technologies for utility installation under surface obstacles. The rapid growth in application of HDD has not accompanied the same level of development in engineering design procedures and efficient drilling techniques. Rational engineering design and maximized drill rate are of a great value particularly in longer HDD crossings where the project budgets are in the order of millions of dollars and daily delays cost tens of thousands of dollars (Baumert and Allouche, 2002). To improve predictions of pulling load by current design practices, exact equations for annular flow are derived in this thesis to accurately compute the fluidic drag during HDD operations. Comparisons of the exact solution with the predictions by design procedures such as PRCI and ASTM 1962 reveal that PRCI overestimates the fluidic drag while ASTM F1962 results in a better estimation. To maximize the rate of penetration and identify underground drilling risks, the concept of Specific Energy (SE) of drilling is proposed here to be used in HDD. SE has been implemented successfully in oil and gas industry as a useful efficiency indicator of drilling operations. To calculate the real SE used by the bit to excavate the material, downhole drilling data should be measured during the process. Utilization of sophisticated downhole measuring tools is not economical in HDD. Therefore, a mechanical model is developed to calculate downhole loads and torques using the result of the previous analysis on the fluidic drag. Finally, an example application of SE in HDD is illustrated in a case study and the SE analysis for surface and downhole conditions are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Horizontal Directional Drilling (HDD) has become one of the fastest-growing trenchless technology construction methods for the installation of underground pipelines and conduits. According to the board of directors of the Ohio Horizontal Directional Drilling Association (OHDDA), there are many HDD specifications employed in Ohio, and these specifications vary significantly in their content and requirements. Consequently, inferior products may have been installed, unnecessary risks may have been taken, and the competition among contractors may have been compromised. Therefore, a HDD specification that provides for high quality installations, allocates risks appropriately, and ensures correct design and installation of product pipes without damaging the roadway is needed. The proposed draft was based on comparison of more than 12 existing HDD specifications with the HDD Good Practice Guidelines and the collective input from professional partners representing the interest of the various entities involved in a typical HDD project. The research team along with the professional partners proposed draft specification for pressurized applications with pipe diameters in the range of 4 inches (10 cm) to 24 inches (60 cm). Installations outside this range of pipe sizes and gravity installations are beyond the scope of the specification. The implementation plan for the draft specification includes ODOT review to ensure it does not conflict with other ODOT specifications, ODOT evaluation of the proposed specification through use on an actual project, feedback from the larger interest groups across the state of Ohio, and update as needed.

Download or read book Real Time Data Acquisition and Prediction Model Comparison Using Maxi Directional Drills written by Kyle Verwey and published by . This book was released on 2013 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horizontal Directional Drilling (HDD) is used around the world when traditional open cut methods are not practical or impossible for installing pipelines. Maxi-sized drill rigs are the largest and most powerful directional drills and are more common in the field than ever before with over 5,000 rigs in operation world wide. The complexity of installations and the design associated with them continues to increase. This research has two main objectives. 1. Develop a real time data acquisition system for monitoring pullback forces on the product pipe; and, 2. Compare data gathered using maxi-sized drill rigs with current modelling methods using BoreAid. The first portion of the research, as listed above, required attaching multiple pressure transducers to the drilling display panel in an American Auger DD-1100 drill rig and recording, in real time, the carriage, rotation, and mud pressure as seen by the operator. This research also describes the various challenges and issues associated with developing real time in-the-bore data acquisition processes. Finally, future recommendations for further development of the in-the-bore data acquisition are discussed. The second portion of this research describes how the gathered data was processed into a workable data set. The field data was then compared to theoretical models by using the drill assistant tool BoreAid. The results of this comparison show that these models are appropriate for all size drill rigs, although some limitations are present.
