Abstract Reduced lateral spacing in congested oil and gas fields requires advanced techniques to prevent collisions while drilling. Anti-collision separation factors depend on the accuracy…
Abstract Unplanned sidetracks are low-frequency high-cost events that have meaningful negative impact on the economics of oil field development. While it is clearly desirable to…
Abstract Standard directional surveying practices are subject to numerous error sources which can cause inaccurate placement of the wellbore. This is problematic because inaccurate wellbore…
Abstract Accurate wellbore placement is of key importance in producing and developing unconventional resources. For cost reasons, unconventional wells areusually drilled with gamma radiation data…
Abstract Finding an optimal lateral spacing is crucial to maximizing the return on investment for unconventional assets. The estimates regarding these lateral spacings were made…
Abstract Optimizing lateral well spacing is a challenging problem that has significant economic consequences. The intent is to drill the fewest number of horizontal wells…
Closed-loop geothermal presents a unique opportunity, with relatively few constraints to satisfy (e.g. target depth, lateral length). This study uses this freedom in trajectory design…
Abstract Optimal wellbore placement and collision avoidance requires accurate real-time steering of directional wells. Uncertainties in the wellbore position are accounted for by industry standard…
Abstract In unconventional resources, horizontal wells are drilled in parallel at a spacing distance designed to maximize drainage of the reservoir. Lateral well spacing should…
Abstract This paper describes a study using an autonomous marine vehicle with satellite communications, to accurately collect and deliver in real-time magnetic measurements, to calculate…
Abstract We present a study conducted to develop and validate new capabilities for offshore geomagnetic surveying that employs the autonomous marine vehicle (AMV) to map…
Abstract Positional uncertainty is a critical component of managing collision risk while drilling. Ensuring that survey data meet the requirements of their uncertainty models has…
