Program Topic: “Automation and Clear Brine Fluids"
1. Alan Mclauchlan (Halliburton)
Presenting – “All Electric Benefits from CAPEX to OPEX”
In today’s environment, operators are looking for ways to reduce spend on CAPEX and OPEX while still having the capability to enhance equipment performance over the life of the well. Typically cost reductions result in the use of standard technology, which can often result in lost production or less reliable equipment versus more advanced completion systems.
All-Electric Completions enable project cost reductions by removing costly hydraulic systems from the subsea production systems and host platforms. Studies have shown that projects deemed previously too uneconomical to proceed with the use of conventional systems can now be pursued thanks to higher specification technologies, which enable enhanced monitoring and control of the reservoir.
As technological advances in subsurface technologies have progressed, operators now have the capability to capture parameters that were previously a challenge to measure with conventional systems. All-Electric Completions are enabling faster and more informed decisions, and when combined as a total system can have a significant impact on operating costs while maintaining optimum well performance and longevity.
Alan Mclauchlan, with 25 years industry experience across the oil and gas sector, Alan has a proven track record in the development and introduction of new technology and driving commercially successful safe, quality orientated environments. Responsibilities have included; country management, business development, technology development and introduction, development of strategic partnerships and Joint Ventures, strategy development and project leadership.

2. Katherine Price Hoelscher and Ethan Peterson (MI SWACO)
Co-presentations – ”Diagnosing Operational Health Through Automated Drilling Fluid Sampling and Digital Technology”
Our industry is witnessing the early adoption of the fourth industrial revolution of digital technology. Changes within our industry demand a quick response to increase our already high level of planning accuracy and operational performance. Autonomous digital systems hold the key in reducing overall risk while increasing the benefits from expedited and more detailed analysis. A key benefit is liberating our subject matter experts from repetitive tasks, allowing them to focus on solutions for drilling effectively by using automation and effective data communication to a single database. Data, like oil, provides many benefits when stored in its crude form. Before useful data is accumulated, it must be acquired using fit for purpose methods and instrumentation to ensure accuracy as well as optimal frequency. Inaccurate data will only lead to inaccurate conclusions, and isolated data points are meaningless without surrounding data to offer context. The biggest challenges we face involves bringing data from so many sources together in a repository that has the proper context required to transform the data into useful information. This practice of incorporating accurate, structured and contextual data in a secure, customer empowered cloud environment is the clear future of the petroleum industry.

Experience in a variety of drilling situations lead to opportunities as a Project Engineer, technical service, sales & commercial and management positions, prior to beginning his current role in early 2020. He joined the digital program in 2020. He received a BS in Forensic Science and Chemistry form Weber State University in 2007.
3. Oya Karazincir ( Chevron)
Presenting – “Fluid Loss Control – Design and Application in HTHP Completions and Depleted Formations Using Custom Laboratory Analyses”
Fluid-loss control pills are used to manage and mitigate excessive and unanticipated fluid-losses that are observed during well completion and fracturing operations. The increased focus on development of HPHT oil and gas fields has introduced new challenges in fluid-loss control pill design. Stability of the carrying fluid/viscosifier systems at HPHT conditions, particle sagging, pill compatibility with high density acidic brine systems and density segregation, solids loading/particle size selection to seal against more challenging fluid-loss zones, pill removal and formation damage are some of these challenges. For successful fluid-loss mitigation, a pill system needs to be designed with these challenges in mind. In addition, the differential pressures across the zones to be completed and the overbalance conditions that can be encountered during completion operations need to be well understood. This presentation will cover examples of recent studies on fluid-loss control pill design for HPHT fields, including highly depleted formation zones. A summary of custom laboratory tests that were designed and conducted to mimic fluid-loss events under high overbalance conditions will be reviewed and the learnings from these programs will be shared.
Oya Karazincir is a Completion/Stimulation Fluids and Formation Damage Advisor in the Completions SME Chapter at the Chevron Technical Center.

4. Temi Okesanya (NewPark)
Presenting – “Optimizing the Drilling Efficiency and Corrosion Control of Clear Brine Drilling Fluids through the Automated Measurements of Fluids’ Properties”
Proficient monitoring of drilling fluids’ properties is vital to the success of any drilling project. While this responsibility has been manually conducted over the years by the fluid engineer, there has always been a concern of discrepancies, human-induced errors, and the absence of critical data in unmeasured intervals that can negatively affect drilling operations. These concerns are even aggravated in the case of clear brine drilling fluids due to their corrosion potential and dewatering challenges.
This pragmatic study presents results and lessons learned from field case studies in North America (the USA and Canada) where a successful approach was adopted to optimize the drilling efficiency of brine drilling fluids through the live monitoring of the fluid’s properties. Various probes were used for the automated and real-time measurements of brine fluid properties and produced measured data that can be viewed remotely. Rate of Penetration (ROP) data was obtained from an Electronic Drilling Recorder (EDR) software used in the rigs. Weight loss tests on drill pipe corrosion coupons were used to determine field corrosion rates. An effective solids control system was used to remove solids when measured solids content rose above the pre-determined threshold value.
Surprisingly, it was discovered that a low concentration of drill solids (even as little as 1% v/v) in the brine fluid system can impact corrosion rates greater than some chemical additives. Field results also showed that a decrease in solids content engendered an increase in the Rate of Penetration (ROP). There was a substantial increase in ROP (Over 57.5%) due to effective solids control and monitoring thereby making live and automated monitoring of brine drilling fluids’ properties a priority for drilling optimization.
By leveraging automated data capture and analytics, this digital approach has provided a very potent framework for efficient decision-making and drilling optimization. This approach has provided the necessary foundation for using a wider variety of brines and produced water as premium drilling fluids with similar confidence to an oil-based mud.
