Sand Control
Name: David L. Tiffin, Ph. D.
Education: Ph. D. Chemical Engineering; University of Notre Dame (1979)
No. of years of oil field experience: 35 years; in positions as research engineer, completions engineer, and eventually Sr. Completions Advisor for Amoco and then BP.
What motivates me?

I love helping people succeed and solving technical problems. I especially enjoy working as part of a highly competent and motivated team.

My interest in sand control took shape in early 1990’s when I recognized that all our “growth areas” within Amoco’s strategy required sand control completions. We were neither consistent nor always successful. Among other things, I worked out a methodology to properly size gravel and screens; and then with BP a method to optimize drawdown to maximize rate without jeopardizing completion integrity. I also greatly enjoyed leading all aspects of completion design, operation and installation within BP’s Gulf of Mexico Shelf operations. I like root cause investigations and led several. Later in my career I enjoyed mentoring, coaching, leading and helping wherever BP needed extra completions horsepower.

What I am really good at? I have been especially successful as a member or leading teams working on complex and difficult problems. I get along well with others. I love learning and listening to different perspectives. Even though I have developed a reasonably good reputation in sand control within BP and the industry, I know there is much we don’t know and many areas to improve.

Name: Terje Løkke-Sørensen
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.

Wellbore Stability
Name: Ken Kunze
Education: PhD Chemistry, Rice University Houston Texas, 1978
No. of years of oil field experience: 38 years, ExxonMobile, 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.
