FEWER FRACS = INCREASED PRODUCTION: ENGINEERED COMPLETION VERSUS GEOMETRIC COMPLETION


When a reservoir is fracked geometrically (even spaced fracs) the entire horizontal section is stimulated, both good and poor quality rock. Through the use of geomechanical/reservoir property logs, those non-productive fracs can be eliminated or the frac moved to a more favorable position in the reservoir. Rocsol Technologies software can generate a complete set of geomechanical/reservoir property logs from drilling data without the use of downhole tools. These logs can be used to help operators place fracs in the best rock[ima

Investigations of a shale formation revealed that stimulating with an engineered completion design leads to lower breakdown pressures, higher treatment rates, higher proppant placement, and increased hydrocarbon production. In the table below, wells 1, 2, and 3 were completed using a geometric or nonengineered stimulation design. Wells 4, 5 and 6 were completed using an engineered selective stimulation design. The “Completion Summary” and “30-Day Cumulative Production” indicates a more effective completion design in that lower breakdown pressures, higher pumping rates, more effective proppant placement from the wells completed using an engineered selective stimulation design are achieved based on the geomechanical properties in the shale formation.

Rocsol’s advanced geomechanical synthetic logging software can assist you in engineering your completion to achieve more effective fractures and higher production. Contact us today to have a look at your wells.

The above logs, from 3 North American unconventional horizontal wells, were generated without any down hole tools using Rocsol’s D-Series software. Most companies don’t realize that they have enough existing data from the drilling of a well and information from offset wells to accurately create a geomechanical and reservoir property log without running a suite of downhole tools. The Rocsol D-Series logging technology uses routinely collected surface drilling data (EDR data) to calculate geomechanical properties using two modules, D-WOB and D-ROCK. No downhole tools are required. The system uses a combined three-dimensional torque and drag (T&D) model to estimate the effective DWOB profile from the horizontal well drilling data. An inverted rate of penetration (ROP) model integrated with the drill bit cutting effects, bit wear effect as a function of drilling data and rock abrasiveness to calculate more accurate profiles of rock strengths, Young’s modulus, porosity, permeability, and Poisson’s ratio. Brittleness and a stimulation index can then be calculated using Rocsol’s latest software development.
