Implementation of Managed Pressures Drilling (MPD) techniques provide substantial advantages for addressing difficulties in challenging wells. These benefits include not only the early influx and loss detection, but also Dynamic Influx Management. MPD provides the ability to circulate out an influx at drilling circulation rates while remaining within the primary well control barrier. Dynamic influx management is a trending topic within the industry, with its importance capturing the attention of planning and operational teams, regulatory bodies, and industry interest groups tasked with the development of recommended practices. Evolving from conventional kick tolerance to MPD kick tolerance has enabled dynamic influx management milestones, such as the adoption of the MPD operational matrix. More recently, the novel approach of the Influx Management Envelope (IME) has been increasingly adopted by the industry. This paper presents the state-of-the-art engineering analysis and operational considerations for dynamic influx management during MPD operations. As part of an integrated approach, this work considers three main aspects; 1) MPD kick tolerance, including concepts and its variables of interest, 2) IME generation and parameter sensitivity analysis, 3) generation of an MPD operational matrix. In addition, the advantages and disadvantages of various approaches to determining the limits of dynamic influx circulation are discussed.
Engie delayed its decision to sign a 20-year, $7-billion supply contract with NextDecade’s 27-mtpa Rio Grande LNG (RGLNG) project in Brownsville, Texas, following emission concerns from the French government. France has a 23.6% stake in Engie, which informed Reuters its board decided on 30 September it would give itself more time to study the contract, which “required a more detailed examination”. The supply deal would run until 2045, with exports expected in 2026. NextDecade did not address the matter, but already has plans in place to reduce emissions. The company said in July the project would utilize five LNG trains instead of its original plan for six.
The current presentation date and time shown is a TENTATIVE schedule. The final/confirmed presentation schedule will be notified/available middle of October 2019. If we have learned anything from the North American experience, unconventional resources cannot be exploited by small incremental projects. If we are to be successful in developing these types of reservoirs, we have to make project scale operations work to bring these resources to market in a timely manner. A number of Eastern Hemisphere unconventional gas projects have raised interest, neared completion or are commencing deliveries.
Zainab Titus holds a B.Eng. with First Class Honours from Covenant University, where she graduated as the most outstanding Petroleum Engineering Student in 2015. Owing to her interest in Physics and the numerous awards she had won in Mathematics Competitions locally and nationally during her secondary school days, it was not difficult to identify her predisposition to engineering. Zainab developed a predilection for Petroleum Engineering when on a road trip, she was fascinated by the sophisticated equipment and technology used for oil prospecting activities in the Chad basin of Nigeria. Zainab's engagements with SPE International began in 2013 through her University Student Chapter, where she served as the Technical Officer in 2014. She also interned with ExxonMobil Nigeria and the Nigerian National Petroleum Corporation (NNPC) in 2014, where she worked on projects related to well testing, annular pressure build-up analysis and petroleum economics.
Obi C Edmond Jnr is a Petroleum Engineering graduate student at the Harold Vance Department of Petroleum Engineering, Texas A&M University. Obi Edmond earned a BEng in Petroleum Engineering (First Class Honors) from Covenant University, Nigeria, in 2018 having been found worthy of character and learning. Obi Edmond has been an active member of SPE International since 2015 volunteering in various capacities such as social, technical, Petro quiz team, and served as the Treasurer of the SPE-Covenant University student chapter. Edmond has interned with the Nigerian National Petroleum Corporation (NNPC). His undergraduate thesis, which proffered an improved stability criterion for predicting severe slugging in offshore pipeline-riser systems was motivated from his industrial experience with the Nigeria Liquefied Natural Gas (NLNG).
Decisions in E&P ventures are affected by Bias, Blindness, and Illusions (BBI) which permeate our analyses, interpretations and decisions. This one-day course examines the influence of these cognitive pitfalls and presents techniques that can be used to mitigate their impact. Bias refers to errors in thinking whereby interpretations and judgments are drawn in an illogical fashion. Blindness is the condition where we fail to see an unexpected event in plain sight. Illusions refer to misleading beliefs based on a false impression of reality. All three can lead to poor decisions regarding which work to undertake, what issues to focus on, and whether to forge ahead or walk away from a project. Strategic thinking and planning are key elements in an organisation’s journey to maximise value to shareholders, customers, and employees. Through this workshop, attendees will go through the different processes involved in strategic planning including the elements of organisational SWOT, business scenario and options development, elaboration of strategic options and communication to stakeholders. Examples are provided including corporate, business unit and department case studies. This seminar will teach participants how to identify, evaluate, and quantify risk and uncertainty in everyday oil and gas economic situations. It reviews the development of pragmatic tools, methods, and understandings for professionals that are applicable to companies of all sizes. The seminar also briefly reviews statistics, the relationship between risk and return, and hedging and future markets.
SPE, through its Energy4me programme, will present a free one-day energy education workshop for science teachers (grades 8–12). A variety of free instructional materials will be available to take back to the classroom. Educators will receive comprehensive, objective information about the scientific concepts of energy and its importance while discovering the world of oil and natural gas exploration and production. Energy4me is an energy educational public outreach programme that highlights how energy works in our everyday lives and promote information about career opportunities in petroleum engineering and the upstream professions. SPE’s Energy4me programme values the role teachers and energy professionals play in educating young people about the importance of energy.

This course covers the fundamental principles concerning how hydraulic fracturing treatments can be used to stimulate oil and gas wells. It includes discussions on how to select wells for stimulation, what controls fracture propagation, fracture width, etc., how to develop data sets, and how to calculate fracture dimensions. The course also covers information concerning fracturing fluids, propping agents, and how to design and pump successful fracturing treatments. Learn more about training courses being offered. Current and future SPE Section and Student Chapter leaders are invited to engage and share.
A federal judge ordered the US Army Corps of Engineers to conduct a full environmental review of the Dakota Access pipeline, nearly 3 years after it began carrying oil despite protests by people who gathered in North Dakota for more than a year. Additional environmental review of the disputed Dakota Access oil pipeline is likely to take the rest of the year to complete, US officials said in court documents in which they also advocate for keeping the line operating during the study. A federal judge ruled on 14 June that the environmental review for the Dakota Access pipeline was, in part, inadequate and must be reconsidered, handing tribal opponents of the 1,170-mile pipeline project a key legal victory.
