PZS™ PayZone Steering
Real-Time Forward Modeling
PathFinder’s PayZone Steering (PZS) service includes high quality real-time LWD measurements and a software system for interpreting the log responses and proposing adjustments to the well plan. In addition to identifying the position of the well in the geologic section, PZS is used to predict lithology ahead of the bit. These services can be provided to the geologist at the wellsite or at an offsite location.
PathFinder includes the following components as part of a complete interactive service with several remote communications options:
- PayZone Steering expertise
- PayZone Steering Modeling Software
- Formation Evaluation Sensors
- At-Bit Inclination and Gamma Ray Sensors
The key to the PayZone Steering service is the PayZone Steering (PZS) software suite along with the expertise of the engineers involved. The reservoir navigation process is very much focused on successful teamwork between all parties involved. The PZS software provides a working model that is updated from real-time MWD and LWD measurements to enhance the decision making abilities of the team.
The PZS software has been developed from the geological steering of deviated well paths. This powerful functionality is achieved by combining the geological earth model, the directional well plan and the petrophysical data from real-time LWD logs into a single modeling program.
PayZone Steering utilizes log responses, and the correlation of those log responses with modeled synthetic log responses, to determine the stratigraphic position of the well path, or the position within the geologic sequence. Real-time data from sensors located in the drillstring are continually fed into the PayZone Steering program from the PathFinder surface system to enable real-time answers to the questions posed during drilling:
- Where is the bit now?
- Where is the well heading?
- Where should the well be heading?
