Methods, systems, and computer program products for developing and presenting wellbore pipe string related operation engineering parameter roadmaps in hydrocarbon reservoir modeling are disclosed. A computer-implemented method may include receiving a plurality of depth intervals, associating different computational model calculations with each depth interval, selecting input parameter values for each set of computational model calculations, generating computational model results for each set of computational model calculations associated with each interval to yield a graphical interval plot for the depth interval; and displaying a plurality of graphical interval plots together on a wellbore roadmap. A control list for the roadmap is correspondingly generated and dynamically linked to the wellbore roadmap so that individual entries in the control list are associated with individual interval plots.

Methods, systems, and computer program products for range-based sensitivity analysis in hydrocarbon reservoir modeling are disclosed. A computer-implemented method may include receiving a first numeric range defined as a minimum value and a maximum value for a first input parameter of a computational model, computing a different computational model result for each of a plurality of values in the first numeric range by using each of the values as the first input parameter in different respective computational model calculations, and displaying results of the computational model calculations.

A trip speed table is created containing records. Each record contains a step location, wherein a step is defined to be the location in a well of a deepest end of a drill string, a minimum trip speed for the step location, wherein the minimum trip speed is defined to be the maximum trip speed less than or equal to a default trip speed at which the drill string can be tripped without exceeding a fracture gradient or falling below a pore pressure at a slice depth, and the slice depth where the minimum trip speed for the step location occurred.

Estimating and predicting wellbore tortuosity. At least some of the illustrative embodiments are methods including: receiving, by a computer system, an indication of rotational drilling time and slide drilling time for a wellpath; calculating a value indicative of tortuosity for the wellpath based on the indication of rotational drilling time and slide drilling time for the wellpath; determining, by the computer system, that the wellpath exceeds a tortuosity threshold, the determining based on the value indicative of tortuosity; and changing a drilling parameter regarding the wellpath responsive to determining that the wellpath exceeds the tortuosity threshold.

Calibrating Friction Factors. At least some of the illustrative embodiments are methods including: calibrating friction factor for a drilling operation by: plotting on a display device the expected hook load versus depth for the drilling operation; displaying plot points on the display device, each plot point indicative of a measured hook load versus depth for the drilling operation; selecting a plot point associated with a depth, the selecting responsive to a cursor hovering over the plot point on the display device; displaying a friction factor values which correlates the expected hook load versus depth for the particular depth to the measured hook load versus depth for the plot point, selecting the value responsive to the cursor hovering over the value; and then shifting on the display device at least a portion of the indication of expected hook load versus depth based on the value of friction factor.

Method and system for performing friction factor calibration

Drilling system and methods may employ a weight-on-bit optimization for an existing drilling mode and, upon transitioning to a different drilling mode, determine an initial weight-on-bit within a range derived from: a sinusoidal buckling ratio, a helical buckling ratio, and the weight-on-bit value for the prior drilling mode. The sinusoidal buckling ratio is the ratio of a minimum weight-on-bit to induce sinusoidal buckling in a sliding mode to a minimum weight-on-bit to induce sinusoidal buckling in a rotating mode, and the helical buckling ratio is the ratio of a minimum weight-on-bit to induce helical buckling in the sliding mode to a minimum weight-on-bit to induce helical buckling in the rotating mode. The ratios are a function of the length of the drill string and hence vary with the position of the drill bit along the borehole.

Ratio-based mode switching for optimizing weight-on-bit

Graphical User Interface (GUI) facilitated centralization methods and system, including a method that includes displaying a graphical representation of a tubular string within a borehole, accepting an interactive graphical selection of a starting location for a range along the borehole, and accepting an interactive graphical selection of an ending location for the range along the borehole. The method further includes determining string stand-off device positions that provide centralization within the range, and providing said positions to field personnel assembling and placing the tubular string in the borehole.
