Presenting – “Drilling through narrow pressure windows with superior performance and minimal risk.”
As offshore drilling has gradually moved into more difficult areas, it is now common to encounter challenging wells where pore pressure, fracture gradient, and complex geometry combine to create a very narrow operating window, resulting in operational problems, that can lead to catastrophic lost-circulation events, which propel increasing the overall costs of the projects.
The Low-Pressure-Impact drilling fluid allows an effectively navigation through narrow pressure windows with superior performance, meeting drilling objectives and minimizing drilling risks. This system has been developed not only to minimize ECD but also to reduce the hydraulic impact that the fluid impose on the formation, with optimal hole cleaning properties, and overall pressure reduction.
The system futures a unique mixture of specialized clay and polymers in an advanced formulation that creates a non-progressive gel structure that reduces hydraulic impact with a rapid-set/easy-break profile, protecting the formation against excessive pressure spikes, induced fractures, and the risk of costly mud losses.
In order to illustrate the benefit of this “Low-Pressure-Impact” System, this paper will be presenting the results of field application with emphasis on the performance achieved in terms of extraordinary ECD management and reduction of typical massive losses circulations.
Wallan Pessanha has over 15 years of experience in the oil & gas industry. He started his career as a field engineer at Baker Hughes in Deepwater Brazil, after that worked as Technical Manager for Latin America Region before moving to the United States in 2018. Currently based in Houston, he is the Emulsion Product Line Manager for drilling and completion fluids for Baker Hughes, a GE company. His expertise is in Drilling Fluids and Deepwater Wells operations fluids. He holds a bachelor’s degree in petroleum engineering.

Presenting – “High Internal Phase Drill-in Fluid and Filter Cake Removal System for Deep-Water Injector Wells”
The design of a high density high internal phase nonaqueous reservoir drill-in fluid that would minimize formation damage, while managing reactive shales and ECD has always presented a challenge. Coupled with the requirement of a filter cake removal system that would provide delay necessary for complicated displacement procedures and tripping out of a long lateral section at high temperature, an innovative and novel approach is necessary. M-I SWACO has developed a system (reservoir drill-in fluid and filter cake removal) to address requirements of rheology, thermal stability, breaker delay, and a clean-up. Using this system in a field trial, a reservoir section of the injector well was successfully drilled and completed. The injectivity test, conducted after completing the well, exceeded client’s expectations.
Albert Okhrimenko acquired his Masters’ degree in Chemical Engineering from Russian University of Chemical Technology, in Moscow. He completed his doctoral degree in Photochemical Sciences focusing on nanomaterials and spectroscopic methods of analysis at Bowling Green State University in Bowling Green, Ohio. Albert is currently, as a Senior Technical Service Engineer in Wellbore Productivity group at M-I SWACO/ a Schlumberger company.
Vaughn Traboulay is Technical Service Engineer at M-I SWACO/ a Schlumberger company with a B.Sc. in Chemical and Process engineering from the University of the West Indies. He has 9 years of experience in oil and gas, working in both technical and operational roles.

Presenting – “Continuous Improvement Leads to a Better Direct Emulsion System”
Baroid’s North American direct emulsion drilling fluid system was first used during the summer of 2017. The fluid was designed as a stable, low density, low rheology fluid using saturated saltwater to avoid washing out salt sections during the drilling process. The system was successful with multiple operators, but limitations began to erode its further application growth. The original system began to experience increased viscosity issues with produced water or when drilling anhydrite. Further, the system became unstable at oil content greater than 40%, limiting its lower density range.
The system was returned to research and development to address these shortcomings and help improve system utility. Ultimately, the new emulsifier system selected helped eliminate the incompatibilities with divalent ions and allowed 50% and, in some cases, 60% oil to be added without system instability, allowing even lower densities than the previous iteration. The system retained its low rheology and static stability properties. The new emulsifier system has completely replaced the old system and has currently been used successfully to drill more than 15 wells.
Dr. William (Bill) Shumway, Ph.D. Organic Chemistry, Texas Tech University, started at Halliburton in 2001 as a research and development chemist working on drilling fluids. He went on to become team lead for the drilling fluids R&D group for over four years. He went on to work other technology roles including, New Product Champion, Global Technical Expert for the Shell and Exxon accounts and internal Intellectual Property Liaison. He is currently a Senior Technical Advisor to the drilling fluids R&D group. Bill has been instrumental in the development of several oil based, water based and reservoir fluid systems, as well as additives for each. He has over 25 US issued patents and several technical papers related to drilling fluids.
Deadline for reservations is Friday, February 14, 2020.
