USA Chapter Events

Monthly Lunch & Learns

At these regular monthly events, networking and lunch are followed by a concise, topical technical presentation. With an emphasis on case studies, this bite-size event consistently provides members and their guests with a look at the latest and greatest that the industry has achieved.

Lunch & Learns are typically held the 2nd Tuesday of every other month. Notifications will go out if one is postponed or cancelled.

We’re starting an offshore section of the ICOTA USA chapter. This section is going to focus on all types of intervention work being performed in the Gulf of Mexico, from new deep water subsea completions to P & A work on the shelf. The goal is to bring to light the existing and new challenges of today’s offshore well intervention industry and help solve these issues by improving communication and promoting technical awareness.

We are always accepting abstracts for presentation. Contact me if you are interested

"Using Procedure Modeling Tools to Improve Coiled Tubing Drill-out Efficiencies and Reduce Costs"
Speaker: Nathan R. Hutchings, Ph.D., President & COO, Emerald Surf Sciences

816 Town & Country Blvd, Houston, TX 77024 

Traditional coiled-tubing modeling tools focus primarily on pipe mechanics and cannot accurately predict temporal and economic consequences of complex procedural decisions such as short trip frequency, fluid pumping rates and volumes, chemical cost, surface equipment and rental costs, and pipe charges. Using a new and unique procedure modeling tool to assess temporal and financial consequences of multiple procedure variants, the efficiency of coiled tubing drill-outs has been substantially improved and costs substantially reduced.

The procedure modeler was applied by setting a set of target pressures and flow rates that have been proven to exceed the minimum requirements for efficient well-bore debris removal. Expenses are loaded into the model to reflect surface equipment, fluid costs, personnel, chemicals, and tools. Target reel speeds are entered based on segment of the well and in which direction coiled tubing is traveling. The Darcy-Weisbach equation is utilized to model flow rates and anticipated friction reducer dosages in multiple pipe sizes. Short trip timing, speed, and target depths are entered along with desired pauses and/or circulation events. The chemical program can be delineated in great detail and reflect the use of multiple chemical additives in the slickwater system as well as the size, viscosity, and timing of any gel sweeps.

The procedure model instantaneously generates a step-by-step procedure model that tabulates the timing and fluids at each step as well as a summary page that totalizes all of the entire procedure. Once a baseline procedure is constructed, additional variants of that procedure can be created, modified, and linked together in order to contrast the temporal and economic consequences of each variant. Furthermore, post job analysis allows actual outcomes to be compared to the modeled procedure for accuracy and improvement on future jobs.

Examples will be detailed to demonstrate how this tool has reduced drill-out costs by 20-60% through pre-job optimization with integrated temporal modeling.
