The IADC Drilling Engineers Committee’s 19 September Technology Forum, “Contemporary Challenges in Exploration Drilling,” will take a look at some of the technologies being developed to address the primary challenge that differentiates exploration from development drilling: operational risk. Today’s greatest risk is acknowledged to be within the ultra-deepwater environment, where operators are drilling complex wells with high deviations and narrow mud weight windows. The result is either significant nonproductive time or, in worse cases, elevated well control issues due to swabbing or surging the formation. The Tech Forum will include presentations of technologies that help the industry to improve its decision making and to improve safety and reliability.

The event is hosted by Weatherford at its facility at 11909 Spencer Rd in Houston, from 08.00 until 13:00. Lunch will be provided by Weatherford. The front parking area will be cordoned off and identified as RESERVED PARKING for attendees. Please begin parking from east to west (left to right as you enter the parking lot) in this cordoned off area as spots are available. Back-in parking is required.

The goal of the Tech Forum is to foster a discussion on how industry is responding to exploration challenges.

In addition, spokespersons for DEC joint industry will provide updates on their work.

Agenda:

08.00-08.20     Refreshments and networking

08.20-08.30     Welcome & review agenda– Dennis Moore, Marathon Oil, Chairman

08.30-09.15     JIP Updates (DEC-1, DEC-2, DEC-4 to be invited)

  • JIP DEC 1 “Drilling Systems Automation (DSA) Roadmap”: Robin Macmillan, National Oilwell Varco and John de Wardt, DE WARDT AND COMPANY (Phase II, Stage I Full Report)

  • JIP DEC 2 “Decision Support for Dynamic Barrier Management” – Amar Ahluwalia, DNVGL (Project description; supporting slides)

  • JIP DEC 4 “Independent Verification and Validation of Sensors and Systems in Drilling: Phase I”, Maria Araujo, Southwest Research Institute (Project description; supporting slides)

  • JIP DEC 5“Data Science for Life Cycle Assessment of Dual Fuel Diesel Engine Technology,” Carolyn LaFleur, HARC Environmentally Friendly Drilling Systems (Project description; supporting slides)

09.15-09.45     Program Briefing on Deepstar’s Drilling, Completions and Interventions (DC&I) Committee: Dave Barrow, Senior Advisor for Subsea Completions, Chevron, and Co-Chairman of Deepstar DC&I Committee, and Halvor Kjorholdt, Leader Drilling and Well Solution, Equinor

This presentation will provide a review of Deepstar’s past and recent research efforts, with a focus on the current portfolio of projects and opportunities. These include shear ram technologies and a fast fix to SCSSV issues. There are near-term, as well as potentially long-term, implications for making progress on both of these topics, which have generated multiple suggestions for future study that Deepstar members have put forward.

09.45-10.15     A New Acoustic Telemetry System Enables Deepwater Operators to Manage Pressures in Real Time from Drilling Through Completion Installation: Andy Hawthorn, Director of Solutions, XACT Downhole Telemetry

This presentation will focus on the use of a new acoustic telemetry system, how it works, and how it is being used to manage risk in deepwater applications from drilling to completion installation.

10.15-10.45     The Challenge of Using New Technology:  John Dale, CEO, Electrical Subsea & Drilling AS

This presentation will examine reasons for the long lead times to introduce new technology into the drilling industry.  Even product with great potential to reduce cost and increase safety are rarely adopted with any great speed.  This presentation will focus on the experience with one company’s electrical BOP and subsea RCD for riserless drilling.

10.45-11.00     Break

11.00-11.30     Increased Performance and Reduced Risk as Wired Drill Pipe and Along-string Measurements are Introduced to Exploration Drilling: Tony Pink, SVP Strategic Sales, Automation and Optimization, National Oilwell Varco

The ability to utilize Wired Drill Pipe (WDP) to enable along-string measurements (ASMs) has been discussed previously. The adoption of this technology at a large scale had been limited due to reliability issues and sensors accuracy, but these challenges have been resolved. The deployment of this new generation of tools on extended offshore campaigns has led to a deeper understanding of flow-off events in real time, such as pack offs, severe losses and FIT/LOT data not normally seen in real time. This presentation focuses on the deployment of the WDP, ASM tools and high-speed telemetry in different offshore exploration drilling applications.

11.30-12.00     Downhole Early Kick Detection Sensor: Jim Hall, Director, Letton Hall Group

Current downhole pressure sensors are unable to detect small density changes that would indicate the onset of inflow from a high-pressure zone. Prototypes of a “fluid density sensor” (FDS) module that could be placed in the bottomhole assembly have been developed and tested in a simulated static wellbore-like test stand with fluids varying from water, salt water (brine) to mud with a density up to 18 ppg. The FDS sensor’s density response was linear over the density range and showed a sensitivity to a wellbore fluid density as low as 0.1 ppg, which would be sufficient for real-time kick detection and well control. This sensor would complement a typical PWD tool, which measures the entire annular pressure gradient from surface to the BHA. The current status of the qualification of the downhole FDS will be presented.

12.00-12.30     Well Complexity and Risk Evaluation through Relief Well Contingency Planning: Joseph D. Burke, Aaron G. Scheet, Wild Well Control

Typically, relief well contingency planning is performed on many exploration wells to help understand the feasibility of a kill operation during a worst-case scenario blowout from the target formation during the final hole section. While this evaluation can provide significant value to the design team for the particular hole section of interest, it fails to provide a true complexity assessment of the well design by neglecting to evaluate all potential flow scenarios leading up to the final hole section, as well as after the well has been put on production. A relief well intervention project is often thought by many to occur primarily for blowout events that take place during drilling operations. However, relief wells are rarely utilized in such an occasion. More often, a relief well is used to perform complex P&As where conventional access through the wellhead/tubulars has been lost and conventional P&A methods cannot be used. This understanding can allow for optimization of the well design to further reduce the operational risk throughout the lifecycle of the well. This presentation aims to overview several critical relief well/intervention well design elements, discuss how relief well planning/modeling techniques can be used to analyze the risk profile for a given well and provide methods on how to optimize a proposed well design for intervention well operations.

12.30-13.00     Active Wellbore Pressure Management – The Key to Managing Uncertainty in a Deepwater Exploration Scenario: Robert Ziegler, Global Director, Well Control Technology, Weatherford

The more uncertain the pressure regime in an exploration well, the higher the value of active and dynamic wellbore pressure management. This presentation describes how closed-system drilling reduces risk to make deepwater drilling more predictable and cost effective. Applications in all phases of well construction in an exploration well will be discussed, as will associated enhanced data collection and the inherent efficiency improvement and cost reductions achievable.
