"I first began using PowerDraw as a technical downhole packer and flow control technical specialist with a major oilfield service company. The program was initially used a tool for the sales staff to visually depict what they would be proposing (bidding) or selling to a client (operator). It soon became apparent to me that the program offered additional benefits for the field district and the personnel in change of preparing the job for delivery or execution. As a technical specialist in change organizing equipment, personnel and managing the execution of the project, I used PowerDraw as a visual aid to define very detailed technical specifications of the equipment which was passed on the field districts. This provided the field personnel with a single page, clear and concise completion make up list. For complex completions and work-overs, the schematic was also distributed to other vendors involved in the project to ensure it was clear which vendor was responsible to supply certain components of the completion. I used PowerDraw in this application for numerous years and feel it was instrumental in many successful completions by ensuring that all parties including the operator were clear on what had to be supplied and by whom.
Another benefit for me was that when drafting complex completion schematics it allowed me to understand, refine as required and clearly define the optimum lengths and configurations of sub assemblies. The “NOTES” section at the bottom of the template was used to define the various components of a particular sub assembly. At the stage of execution on critic, I often hung a schematic on rig floor to allow all personnel to visually see what subassembly was the next one to go into the well. I often received praise from the pipe handlers and rig personnel that a detailed schematic made their roles much easier. In the 13 years I have used Visio based wellbore schematics, I have never had a sub assembly or component of a completion run in the wrong order and I have done well over 200 completion in the time. Some of which have been the most complex land completions in the world.
Since the shale revolution began, the downhole tool industry has undergone a tremendous amount of change. 10 years ago it was rare that 2 or more packers were run as part of a completion. Today in North America, it is rare that 10 or fewer packers are run a part of a completion. More importantly there are numerous flow control and frac sleeves being run as part of these completions. In many case the frac sleeves are equipped with sequentially sized ball seats. In this it is more critical than ever that the components and subassemblies are run in the correct order. A well drafted and detailed schematic in the hands of the field personnel involved in running these types of completion is now paramount. In some cased the schematic is used in the frac spread recorder cab to aid in tracking the stages of the job and the relative ball sizes being deployed.
What may be the single most valuable aspect of the schematic is when the completion has been run and “As Built” schematic has been completed for the well file. Later in the life of the well, the As Built schematic with actual depths clearly defined will provided wireline or coiled tubing operators with a visual understanding of the well profile. The detail of the PowerDraw icons will show these personnel where restrictions exist in the tubing string and at what depths they should exercise additional caution while performing their tasks. Wireline and CT operators are often unfamiliar with some of the completion terminology that would define specific components with a completion therefore a schematic will offer the necessary visual aid to these personnel.
While PowerDraw was initially developed as a tool for completion equipment sales personnel, I feel that it is actually more useful in the field districts, on the rig floor and in the cab of a slickline truck for CT unit. I feel that a current and well detailed schematic is the best tool to communicate the completion design to all personnel both in the office and in the field. "
