Dan Gibson has 35 years of professional experience as a Senior Well Integrity, Petroleum, and Completion Engineer.
Dan is a subject matter expert in complex well integrity issues and completion designs. He was an expert witness in the Macondo federal trial. He was Wells Technical Authority providing technical support and management advice to help the operator manage an aging well population. He helped write/re-write much of the Operator's Well Life Cycle Management System and is quite familiar with the concepts and systems for these documents. Dan retired from a major where he was involved in all aspects of drilling, completion, and production operations. He has worked and lived in 6 countries on 4 continents - from onshore tight gas to offshore high value wells. He has authored or co-authored 6 papers on a variety of subjects. He is an SPE Distinguished Lecturer for 2016/17.
Dr. Walt Lamb, Ph. D.
Education: Doctorate in Physical Chemistry, University of Illinois, 1981.
No. of years of oil field experience: Prior to joining Add Energy, 34 years of international industry experience with Exxon and BP, working primarily as a petroleum engineer, and later as an engineering advisor and operations manager.
What motivates me? Applying specialist knowledge, skills, experience, know-how, and new/evolving technologies, to assist clients in the delivery of safe and cost-effective engineering best practices.
What I am really good at? My flow-assurance expertise includes: formation damage diagnosis, well stimulation (matrix acidizing and fracturing), treating fluid diversion, control and management of mineral scales and asphaltenes/paraffins, water & gas shut-off, production logging, and laboratory methods and testing. I strive to work with clients to help guide engineering decisions and operations, based on sound and thorough technical analyses, state-of-the art lab testing, and proven/practical implementation alternatives.
Morten H. Emilsen
Education: MSc. in Fluid Mechanics from Norwegian Institute of Technology, Trondheim, Norway (1994)
No. of years of oil field experience: 20 years of experience within multiphase flow for the oil industry. I have managed flow assurance and debottlenecking studies for field development projects. I am a well control advisor with experience from a number of blowouts world-wide including Aliso Canyon gas blowout in 2015, Macondo blowout in 2010, Montara blowout in 2009. I co-authored the Deepwater Horizon Accident Investigation Report and testified as an expert witness in US District Court. I have specialized in transient multiphase flow simulations and developed the recognized Olga-Well-Kill software.
What motivates me? Using my knowledge and experience to help operating companies to develop oil and gas fields in a safer and more cost effective way.
What I am really good at? Diagnosing flow conditions and planning tubulars, pipelines and operational procedures to increase oil and gas production and recovery. Flow assurance. Evaluating hydrocarbon fluids and behaviors. Use my content analytical skills and computer programming skill to optimize production. Evaluate kick incidents and blowouts. Planning kill operations.
Education: MSc. in Petroleum Engineering from the Technical University of Trondheim, Norway (1984)
No. of years of oil field experience: 30 years, in positions as drilling engineer, drilling supervisor and project leader for various operating oil companies in Norway and abroad.
What motivates me? My first awakening around well integrity happened early in my working career as Drilling Supervisor on production platform. We had just finished cementing the production casing and had lifted off the riser/BOP to set emergency casing hanger slips. Our contingency plan was to set down the riser/BOP should the well flow up the annulus. Not a very reliable plan, considering that all the things that could go wrong. Later-on, we started to use multi-bowl wellheads whereby avoiding disconnection of the BOP to set hanger and seals. A much safer operation. I find Well Integrity to be the core of the core in well construction and operations – there is always something new to learn and people to discuss it with.
What I am really good at? Through my work for major clients in authoring of well barrier requirements and managing revision #3 and #4 of NORSOK D-010 Well Integrity Standard, I learned a lot about how to identify/select well barriers and related performance requirements well barrier elements. I also lecture these principles in courses and at seminar. I use this knowledge in conducting technical investigations and authoring of reports. With an analytical mind and logical approach, my reports are easy to read and follow. I love to use tables and sketches instead of many words to convey the message.
Education: PhD Chemistry, Rice University Houston Texas, 1978
No. of years of oil field experience: 38 years, ExxonMobil, comprising assignments in Drilling and Completion research, as drilling engineer in Norway (6+ years), as lead drilling engineer for Skene in Aberdeen (2.5 years), and in varied planning and technology support functions (8 months in Melbourne for PNG planning). Most recently worked in Unconventional Resources D&C group.
What motivates me? Engaging in analysis of data to discover what the drilling situation is in any given area (data sleuthing).
What I am really good at? I enjoy approaching new field areas and projects through a review of available experiential data, logs, drill cuttings analysis, and field reports, in order to reveal potential problems such as wellbore stability and lost returns, slow drilling, formation damage, and high non-productive time costs. Once the major difficulties have been identified, detailed attention can be directed toward mitigation and avoidance methods. During my work in Drilling Planning and Unconventional Resources, I often had to draw from my technical background to assess potential operational difficulties in frontier or under-developed areas and identify the necessary technology. Examples include identifying geo-mechanical problems presented by drilling in Papua New Guinea. Also, as one of 5 initial members of our Piceance CO drill team, I reviewed well files and logs from nearly 50 previous “ad hoc” wells that experienced high wellbore-related NPT, and created a major part of the Well Design Basis document. More recently, I engaged in “data sleuthing” into Chinese well reports and logs to assess the costs and difficulties of remediating or abandoning hundreds of wells for a proposed joint venture EOR project at Renqui, China.
I am especially proud of establishing drill cuttings injection as standard technology within my company. Prior to the project I initiated within Esso Norway, this technology was new to the corporation, although it had become standard among other operators in the North Sea, Alaska, and the Gulf of Mexico. As a result, I became the Cuttings Injection Subject Matter expert, published a company manual, and assisted a variety of injection projects including those at Point Thompson AK, Sakhalin Island Russia, and Piceance CO.
My research and field experience with drilling fluids led me to become the Oil Based Fluid subject matter expert for my company, and chairman of the API sub-committee that standardized the use of the Activity Meter to measure the water phase activity of oil emulsion fluids, a property that is critical for wellbore stability and shale stabilization.
