Subject: SPE Dinner Meeting TUESDAY 24th May: Flow Assurance, Completions, Resource Mgt, EOR

Dear members,

We would like to invite you and your colleagues to the May London Section evening meeting. We are very grateful to Roxar ( and to Hays ( for sponsoring this event.


Roxar’s reservoir management software includes the Tempest reservoir simulation suite, the ENABLE history matching and uncertainty analysis tool and the RMS geological modelling program. See for details.


Like the oil and gas industry Hays is a truly global organisation employing 8,000 people worldwide. The scale of our business does by no means dilute our consultant’s technical knowledge of specific sectors, which is very much illustrated by the geosciences and sub-surface arm. This encompasses 14 global consultants with the majority coming from industry back ground and all completing a vigorous technical training course to understand the requirements companies may have, from a seismic team leader to a principle development geologist.

BEFORE DINNER: 5.00 pm – 6:30 pm: “YP Technical Showcase”

Talk1: Optimisation of a Flow Assurance Strategy for a Subsea Tieback

Speaker: Simon R. Davies, BP Sunbury

The role of Flow Assurance is to ensure the successful and economic flow of hydrocarbon from a reservoir to the point of sale. A Flow Assurance strategy consists of a combination of design features and operational procedures that will deliver the required flow rate of the hydrocarbon in a way that is compatible with the upstream source and the downstream facilities, for both steady state and transient operations, throughout the life of the field. An effective flow assurance strategy requires an understanding of the physicochemical issues associated with the fluids, the prediction of the thermohydraulic behaviour in wells, flowlines and risers, and an understanding of the interactions between the multiphase production system, the reservoir and the downstream process over both short and long timescales.

In this example, the Flow Assurance strategy for an existing HPHT gas-condensate tieback is reviewed and optimised. Field data from the current operation is presented and used to validate transient multiphase flow predictions. The simulations are then used to assess the effectiveness of the current flow assurance strategy and to evaluate possible improvements. The steady state arrival temperatures and the associated cooldown times are assessed for a range of anticipated future flowrates and arrival pressures. Thermodynamic predictions for chemical hydrate inhibitor requirements are validated against laboratory data and then combined with transient multiphase flow simulations in order to optimise the injection rates and durations for restart.

Talk2: Optimisation of Well Completion Design in the Presence of Reservoir Uncertainty

Speaker: Kamshat Ussenova, Schlumberger

Horizontal wells with complex completion solutions improve drainage and increase recovery. It is vital to design completion configuration for efficient recovery of deepwater reserves. Critical decisions with regards to completion design require information that is only available after the well has been drilled. Consequently there is, at design time, a high degree of uncertainty, which presents unique challenges when planning the future exploration of a reservoir.

The talk will describe a novel approach, using an automated tool for optimization of completion design, in a framework that accommodates uncertainty and the decision maker’s tolerance to risk. It will demonstrate an integrated workflow, which incorporates geological uncertainty, economics and risk management, in addition to optimized completion design and operating strategy for efficient recovery of reserves.

AFTER DINNER: 7.30 pm-9.00 pm: “EOR – The Time is Now: Its Contribution to World Oil Supply”

Enhanced oil recovery is perceived to have a history of unfulfilled promise. However, both thermal and carbon dioxide flooding technologies have proven successful; surfactant and polymer flooding less so as a result of the sustained oil price collapse of the 1980s.

Forecasts of world oil demand and supply include both undiscovered resources and EOR as significant contributors. With a world resource of some 9 trillion barrels, and production of just 1.1 trillion barrels to date, EOR has the advantage of knowing where its resources are.

In addition, plans to reduce atmospheric carbon dioxide provides an impetus for the implementation of CO2 sequestration projects – these can improve recovery factors worldwide, not just in the Permian Basin. Advances in polymer and surfactant flooding technology, and in oil field tools and techniques, make the application of those processes more robust.

EOR has not been present in the offshore; while applications present logistical as well as technical challenges, the offshore represents a large EOR opportunity.

To achieve and exceed the expectations of EOR’s contribution to supply, innovative political and commercial approaches are needed; for example, agreements regarding CO2 capture and transportation, NOCs and IOCs sharing the risk as well as the reward in EOR applications.

Key idea: Today’s EOR is not your grandfather’s EOR. It represents a major challenge and opportunity, and efforts to realize this opportunity need to begin now.

Paul Bondor retired from Shell after 35 years of technical and supervisory service. He has worked in EOR both in research ( including 5 years as head of EOR research in the Royal Dutch/Shell Group), and in operations, including thermal and CO2 miscible flooding projects, and in pilot tests of polymer and surfactants. He has experience in primary development and waterflooding, both onshore and offshore (including the deepwater GOM). He holds B.S., M.S., and PhD. degrees from Case Institute of Technology. He has authored 14 technical papers.
