... Abstract Offset well analysis is the process of investigating and integrating historical drilling performance from neighboring wells into prospect well design. Traditional offset analysis is a time and resource intensive process that requires a lot of manual input and analysis to make various...

... in-bit strain sensor that measures WOB and TOB in the bit while drilling. This new approach is completely non-invasive and does not change the BHA. Field testing has shown that in many circumstances only 50% of the surface indicated weight reaches the bit and drilling performance suffers including low...

.... Downhole data was captured in order to provide insight into these challenges. A Downhole Dynamics Tool (DDT) was used to capture the data necessary to investigate the drilling performance challenges. The data collected was downhole weight on bit (DHWOB) and torque, downhole bending moments and tool face...

.... This extensive data set enables thorough examination of the variation in the operational parameters and its effect on the drilling performance. Different indices are used to determine and evaluate drilling performance, such as rate of penetration (ROP). Excessive tortuosity in a well can have many detrimental...

Measurements made as part of the control loop have traditionally been located remotely from the drillstring, and therefore, suffer from physical system states that are not directly related to the forces on the bit. As an example, weight measurements from...
