Attaining Optimal Lateral Spacing on Multi-Well Pads via New-Generation MWD Survey Corrections

Please join us on Thursday November 16, 2017 where we will have a discussion about the different methods of detecting and correcting lateral spacing errors, in an effort to eliminate causes of sub-optimal production from multi-well pads. A new survey correction technique will be presented.


Industry focus on unconventional plays, frequently associated with multiple horizontal wellbores originating from a single pad, has driven the need to look more closely at best practices for drilling wells with accurate lateral spacing. The 30-50 meters of lateral spacing error indicated by standard MWD error models are often not reflective of reality, with 60% of MWD survey runs being flagged as out of spec. The impact to production can be substantial. Fortunately, there are methods for reliably achieving significantly more accurate wellbore spacing. Before one can successfully implement one of these strategies, it is important to understand the primary drivers of spacing error and the different techniques that can be used to detect and correct them. Survey correction techniques have both algorithmic and operational aspects to consider. Too often a lack of appreciation for limitations in the algorithmic side of the correction lead to an operational plan that yields little value.

The presentation will discuss the types and magnitudes of errors found in MWD surveys based on a look into quantitative data pulled from actual wells. It will discuss drivers of survey error; including twist, which is not represented in standard MWD error models. Finally, different types of MWD corrections will be covered, focusing specifically on the varying roles and capabilities of IFR, MSA, and FDIR. FDIR (Fault Detection, Isolation, and Recovery) is a new generation of MWD survey correction, which applies aerospace navigation techniques to the problem of wellbore navigation. It was specifically designed to address the East/West accuracy and overall solution ambiguity problems that can cause gross errors in Multi-Station Analysis (MSA) solutions.


Chad Hanak, Ph.D. (Superior QC)

Chad Hanak has an extensive background in navigation and automated systems. He has a Ph.D. in aerospace engineering, specializing in statistical estimation and control theory. Chad spent the first decade of his career at NASA’s Johnson Space Center, where he designed guidance and navigation systems for both manned and unmanned spacecraft. Some of his design work includes aerocapture guidance at Titan and Neptune, low thrust trajectory optimization to Mars and Jupiter, crater-based lunar navigation, and autonomous navigation flight software for the Orion manned spacecraft. Chad left NASA in 2011 to go work for Baker Hughes, where he worked in the R&D department. His work at Baker Hughes and elsewhere includes both active and passive magnetic ranging system developments, among other technologies. Chad is currently the President of Superior QC.
