Horizontal Directional Drilling, as known as HDD, is a method of construction that requires few trenches or no continuous trenches, used for making crossings under rivers, roads and existing structures. In the oil and gas industry, it is most commonly used in offshore and onshore well drilling activities to better explore the reservoir from a single well. It is also very much used when laying pipelines, where no other feasible option is possible. This technology was widely applied in the Urucu-Manaus natural-gas pipeline construction by Petrobras, and Transpetro has been responsible for the operation and maintenance of this pipeline since November 2009, flowing Natural Gas from the heart of the Amazon forest mainly to the growing market of thermoelectric plants. Due to its extension in the forest, the crossing of numerous wide navigable rivers and other natural obstacles was unavoidable, and no other construction methods were more suitable than the HDD technology. This work shows the application of this method in the 1777m long crossing of the Solimões River during the construction of this 662km Natural Gas pipeline. It also shows the challenges faced due to the logistical adversities in the rainforest, as well as the operations by Transpetro.

The crossing of a series of high, parallel, elongated and with steep scarp mountains in the Serrana Province, between Ca´ceres and Cuiaba´, Mato Grosso State, Brazil, constituted a great technical challenge for implementation of the Bolivia - Mato Grosso gas pipeline. Due to environmental preservation, the gas pipeline could not cross the crest of some of these mountains using conventional surface methods and the alternative of surrounding the mountains would have caused an extended additional path, with appreciable additional cost. The economically viable alternative was the horizontal directional drilling through the most critical mountains: Piraputanga Ridge with 850m, Cachoeirinha Ridge with 943m and Palmeiras Ridge with 867m. One of the difficulties was the drilling of the very compact and abrasive Alto Paraguay Group Proterozoic low metamorphic rocks intercalated with clastic sedimentary rocks. The horizontal directional hole intersects in high angles the strongly dipping layers of rocks. The layered sequences of sandstone capped by siltstones provide the aquifer condition to Raizama Fm. with strong water flow. To prevent any environmental damage, the conventional hole design was modified, which allowed the drilling with water, instead of bentonitic drilling fluid. The horizontal directional drilling consisted of a pilot hole with 10.14 inches diameter, drilled with down hole motor and an electromagnetic steering system. The first enlargement of the pilot hole went to 22” diameter and the last one to 30” using special reamer tools. The pipes of the Bolivia - Mato Grosso gas pipeline have 18” diameter, with a special line coating to prevent damages during pulling in contact with rocks. No problems occurred during the pulling operation of the pipes along the holes. The proposed three horizontal directional holes were very successful and the projected designs of the well were fully achieved, with a very small offset in the forecasted exit points. After long weeks of hole opening and preparatory works, all three pulling operations of the pipestrings along the holes went very smoothly.

The Town

In the summer of 2000, TransCanada PipeLines Ltd. (TransCanada) upgraded portions of the Western Alberta System (WAS) NPS 36 gas pipeline through the town of Cochrane Alberta. The pipeline upgrade required the installation of new sections of pipe to meet the higher Class Location designation due to population density increase. Environmental concerns, expressed by federal and provincial regulators and the Cochrane community for the in-stream disturbance associated with a conventional “open cutting” installation, prompted TransCanada to design a directionally drilled crossing. A unique challenge to this project was the Bow River crossing within a congested and restricted right of way. The project team developed and implemented a series of innovative solutions which led to the successful conclusion of the project in September 2000. This paper summarizes the unique design and construction implemented in this project.

The study discusses the issue of introducing drilling fluid (bentonite) into the environment during the construction of linear underground investments, considering the example of the construction of the high-pressure gas pipeline, Czeszów—Kiełczów DN1000, which involved the use of the Horizontal Directional Drilling (HDD) method. The analyses concern the drilling stage as a low-waste technology, indicating the use and management of bentonite drilling fluid in a closed circulation cycle in the area of Pęciszów, poviat Trzebnica (Poland). The loss of drilling fluid in valuable natural areas during the construction stage of the gas pipeline has been analyzed. Drilling fluid is an element of the horizontal directional drilling technology (HDD). The analyzed area included a section of the route of the strategic gas pipeline, realized in June–July 2017 in an area of lowland ash and alder forest 91E0-3, a probable breeding site of the Bluethroat for a detailed description and common frog. The loss of the drilling fluid used in the drilling phase has been determined, depending on the type of soil and the related fraction as well as the possibility of treating the drilling fluid used to construct the drilling.

Mud Pressure

With large-diameter horizontal directional drilling (HDD) becoming the preferred method to construct oil and gas pipelines and utility pipelines beneath rivers, the issue of potential ground collapse arises when drilling in loose geological layers such as sand. Ground collapse is a result of borehole collapse and may cause significant damage to the topography and nearby facilities. The present investigation considered the potential causes of ground collapse induced by an actual 1.219 m diameter HDD river-crossing project, using the FLAC3D numerical modeling tool. The analysis showed that the failure zone first developed at the crown of the borehole, resulting in subsequent borehole collapse due to instability of the sand above, and eventually leading to ground collapse. Sequential reaming cycles have been simulated and the results indicate very little effect in comparison with a single reaming cycle. The risk of borehole collapse, and consequent ground collapse, increases with borehole diameter. Parametric numerical modelling has also been conducted to study the influence of soil parameters and drilling mud pressure on the stability of the ground surface above the borehole. The results show that soil cohesion and friction angle have a large influence on stability of the borehole and ground surface, while elastic modulus and Poisson’s ratio have relatively little effect. It was also determined that mud pressure is a very important factor in maintaining stability of the borehole, and therefore the ground surface as well.

Investment Process

The study presents the application of multi-criteria analysis, i.e., the Analytic HierarchyProcess (AHP), for the evaluation of investments related to the realisation of a high-pressure gaspipeline. The authors evaluated the realisation of the gas pipeline with the use of alternativemethods: the trenchless Horizontal Directional Drilling (HDD) method and the open excavationmethod, based on the example of the construction of a high-pressure gas pipeline DN1000. Sectionslocated in naturally valuable areas on the route of the pipeline Wierzchowice-Kiełczów (Poland)were analysed, on the section from the valve station in Czeszów to the Kiełczów node. The researchconsidered the following criteria: technical costs, economic costs, social costs, and environmentalcosts. The sum of these partial estimations is the “total cost” of the investment. Research revealedthat the technical costs of the open excavation method are in all cases higher than the technologicalcosts of the trenchless method during the realisation of a gas pipeline (in the AHP analysis, theyreceive an average score of −4 or −3, compared to a score of −2 for the HDD method). On the otherhand, the economic costs are comparable, with a slight advantage for the HDD method. The overallscore for the open excavation method obtained with use of the AHP multi-criteria evaluation is, fordifferent variants, approximately −19, while the evaluation of the realisation of a gas pipeline withuse of the Horizontal Directional Drilling method gives a score from −15 to −10, depending on thesection.
