Bross Well Pad – Fort Berthold
HRC Resources, LLC had a challenging well pad, with difficult construction constraints. Our survey crews out of North Dakota and Montana surveyed the location using GPS Survey equipment. The well location was constrained by disturbance limits on all four boundaries of the pad. UELS used an AutoCAD Civil 3D grading model to prepare multi-phase construction options to aid in the construction cost of the well pad. Due to the boundary constraints, retaining walls would be required in order to keep the working space needed on the well pad so that the slope of the pad would not extend past boundary limit. UELS coordinated with the geotechnical firm Braun Intertech to work through the design of retaining wall heights and locations. The grading model information was passed on to Braun Intertech to design the retaining wall systems. The slope locations required a top down and a bottom up pile and lagging system. The top down system was used to construct a cut slope wall that was required to maintain a vegetated buffer between the uphill edge of the pad and a nearby highway. The bottom up system was used on the downhill slopes to retain the soil from the fill side of the well pad. UELS worked closely with the contractor in providing construction survey staking of the locations of the retaining wall piles. In addition to the civil grading, UELS prepared right-of-way and alignment plats for the access road and pipelines to service the well location and our typical well plat package; which contains, bottom hole and surface hole legal plats, production layouts, reclamation layouts, and a SWPPP plan.
