Technical Limit
Knowledge Management
Technical Limit is a component of the Knowledge Management system which allows a company to use existing Well data, Lessons Learned, Equipment Failure and Non-Productive Time information to generate a "Best Case Scenario" plan. The goal of this plan is to reduce well construction and maintenance costs without compromising safety, the environment and the well objectives.
Technical Limit is defined as the perfect performance to achieve an objective limited only by currently available technology and personnel. The Technical Limit is determined for the well design based on the operations program. This operations program is generated from the engineering requirements for the well and capabilities of a specific rig type and crew. The resultant Technical Limit derived drilling and/or well services program is an aggressive operations schedule which maximizes the value of the project and meets the agreed objectives.
DWOP is a key milestone of the Technical Limit planning process. The key objective is to achieve optimum execution of the well program, by defining an optimum planned operations duration for each activity. This involves cooperation of the rig crew and service company personnel. Setting target times creates a “base line” against which actual execution performance can be measured. Therefore, the target times (Technical Limit) created are based around execution of the well program with the actual rig and equipment available.
TL Time = Best time in a Perfect World (TL time) + Local Conditions (Rig Type, Rig Equipment, locally available materials, etc.)
This “base line” plan is then agreed as Target times for the well program in anticipation that value erosion will occur during well construction. Performance is then measured against this base line plan during execution of the well design.
Technical Limit is implemented in OpenWells software through the following areas:
