Technical & Operational Practices Support (TOPS)

Technical & Operational Practices Support (TOPS)

K&M Technology Group's Technical & Operational Practices Support (TOPS) is our premium wellsite support service that is ideal for clients who will be drilling technically challenging wells with complex geological structures and pushing the limits of the equipment or rock strength to successfully deliver the well.  This service is provided by our Sr. ERD Advisors (of whom most have received a degree in Engineering or Science related subject).  It provides support to a variety of aspects of the operation including the engineering facets of well design all the way down to the operational practices used by the driller on the rig floor to ensure that the well is drilled as effectively as possible.  The deliverables from the provision of the TOPS service will be a critical aspect for the execution of the current well and the design of future wells in the program and the conclusions drawn from the end of well report will provide technical justification for any changes to future well designs.

With 24 hour support, the following services will be provided by two K&M Sr. ERD Advisors:

Reporting

  • TOPS reports are prepared and submitted daily, which include a detailed description of the operations, a detailed hole condition assessment, actions and recommendations, roadmap plots including hindcast and lookaheads, and other advanced supporting technical plots and relevant photos
  • Real-time drilling data is compiled daily and reporting includes the observations associated with the ERD Advisors personally evaluating returns (cuttings, cavings, and other solids) at the shakers, collecting data, and performing advanced analysis on the data do develop conclusions and advice
  • Prior to all operations in an upcoming hole section, a Lookahead Report is distributed, which includes Torque, Drag and Hydraulic calculations as well as advanced technical supporting plots and recommendations to encompass the potential operational risks and challenges
  • As the onsite expert in extended reach well construction, the ERD Advisors will review all service provider reports daily and liaise with the other service providers and client representatives to ensure best ERD technical and operational practices are understood and maintained
  • An End of Well Report is provided that includes a compilation of the data collected during the well construction process, Conclusions & Lessons Learned from each of the operations monitored during the provision of service, and recommendations for future wells by section and by operation. The recommendations will also explain how the implementation is achievable and the impact on the operation

Rig Floor Presence and Coaching

  • The ERD Advisor is present on the rig floor to monitor and coach others, as appropriate per scope, in the collection of torque, drag, and hydraulic data while making connections and during any tripping operations.
  • The ERD Advisor provides input, operational parameters, and real time monitoring throughout the cased and open hole portion of casing and liner running operations, including the liner hanger and packer setting sequence.
  • The ERD Advisor provides written instructions and guidance to Drillers on the connection procedure necessary to safely prepare the hole for turning off the pumps, minimize hydraulic surging, collect torque & drag data, and resume drilling, with consideration given to the required surveying procedure.
  • The ERD Advisor is present on the rig floor for all critical operations. The ERD Advisor is trained (and trains the driller and other key personnel) on how to recognize and respond to indications that the hole condition is deteriorating or indications that other risks are developing. These include, but are not limited to signs of an impending pack-off, differential sticking indicators, friction factors departures from the model, hydraulic abnormalities, etc.
  • In case of unforeseen events resulting in restricted or impossible drill string motion (e.g. rig equipment failures), the ERD Advisor provides all required modeling such as maximum allowable torque and overpull and is constantly present on the rig floor until drill string motion is reestablished. 

Hole Condition Monitoring

  • The condition of the well is constantly monitored by evaluating measured surface loads and pressures, ECD, surge and swab, and comparing them to those predicted in the “road maps” which are generated in advance, and updated as required, for the drilling, tripping and casing running operations.
  • Cuttings returned to surface are monitored for signs of abnormalities and technical recommendations for preventing wellbore instability are provided. Advanced analysis with the use of a geo-mechanical model is  used to evaluate any wellbore instability to determine its root cause, and the ERD Advisor provides evaluation of the failure mechanism and advice on how to respond operationally.
  • Model side-forces, provide wear mitigation recommendations, and monitor for signs of casing wear during the job. Reactive modeling and remedial recommendations are provided should drill pipe or casing wear problems occur.
  • Active monitoring for indicators of differential sticking during each of the connections and while running casing and liners

Drilling Operations

  • Perform drill string modelling and optimization for each hole section to minimize the risk of buckling, minimize vibrations, maximize ROP, understand the risk of drill string and casing wear due to side forces and bending stresses, and ensure sufficient overpull margin is available
  • Provide bit and BHA optimization to improve ROP, minimize differential sticking risks, maximize hydraulic efficiency, and improve hole cleaning
  • Provide real-time drilling parameter optimization to improve ROP and identify ROP limits based on analysis of the hole condition as changes are applied

Tripping Operations

  • Surge and swab modeling and advanced tripping schedules are provided with integrated wellbore pressure limits as per the rock mechanics analysis. For future optimization of tripping speeds, post evaluation of the trip schedule effectiveness is performed by comparing the measured downhole pressures to the modelled loads.
  • In addition to tripping schedules, the trip speed will be actively monitored while trips are made to ensure the wellbore pressure stays within the limits established by the geo-mechanical model.
  • When rock mechanics or well design deems necessary, backreaming the drilling BHA out of hole may be required. The ERD Advisor will provide recommendations to ensure that backreaming is conducted with minimal risk, and monitors the critical operation from the rig floor. Backreaming parameters and to what depth backreaming should be performed to, is provided, as well as what hazards to be on the lookout for (pressure increases, erratic torque, hookload variations, formation transitions, etc.).
