NEW FOR 2015:
A new development for DEVEX 2015 is a programme of Masterclasses which will be on offer to all delegates, included within your conference registration. These Masterclasses, lead by experts in the field, will provide an ideal opportunity to brush up on a topic or indeed learn something new. A range of topics will be covered and masterclasses will take place in a venue within the main exhibition hall, along side the technical programme.
Confirmed contributors include:
Uncertainty and Risk in Development
The quantification of risk and uncertainty is often discussed in the context of exploration and appraisal, yet most of the upstream E&P business concerns decision-making in producing assets.
Uncertainty-handling in development and production differs from that in E&A, as it must deal with a growing and often imperfect production database against a backdrop of constantly changing circumstances. As the life cycle progresses, initial uncertainties over volume and productivity narrow but are supplanted by new uncertainties such as sweep efficiency, fine scale architecture and changing responses to new production mechanisms and techniques. These new issues demand a change in approach for the quantification of uncertainty and vigilance is required to avoid the subsurface interpretation simply collapsing on to a best guess.
Getting a Clearer Image of your Reservoir - Understanding Borehole Images and their Application
There is increasing industry usage of borehole images for tasks such as sedimentary body dimensioning, geomechanics, fault description, fault characterisation, structural delineation and fracture typing, spacing and enumeration. Borehole images are perfect for this purpose as they bridge the scale gap between core and seismic data.
A vast array of different image measurement techniques can now be used to acquire borehole images either whilst drilling or during subsequent logging operations. These are dominated by images based upon measurement of electrical or acoustic properties in the wireline realm, whilst in the LWD realm images include those based upon electrical measurements, and also a range of nuclear measurements including gamma ray and density images.
The choice of imaging devices can be very confusing, and it is often forgotten that different image types have different sample resolutions that will affect their utility. So, given that not all images are equal, when faced with choosing what image technology to use, you need to answer the questions you have about your reservoir, what are the factors that you should consider?
This presentation will aim to outline the advantages/disadvantages of different imaging technologies, and some of the factors that can impact upon deciding which technologies might be best to help deliver the data required or answer a specific question. We will also examine some of the QC pitfalls that are often overlooked and are increasingly affecting image data sets and attempt to show some of the wealth of information that borehole images can provide.
Reservoir Quality Analysis
This masterclass will present simple methods to interrogate a tabulated mineralogical dataset to determine controls on the reservoir quality of a reservoir. The focus will be on analysis of automated petrography (QEMSCAN) datasets, illustrated using data from two UKCS reservoir sequences.
Understanding PVT: The Importance of Fluid Characterisation - Examples from Central North Sea Gas Condensate and Oil Fields
The fluids PVT behaviour plays a very important role in characterising the processes occurring within the reservoir. Observation of the production data, and phase behaviour of the fluid (PVT data), can assist both production and reservoir engineers in characterisation of production mechanisms controlling reservoir behaviour. A good understanding of the drive mechanism, depletion status and well performance issues can be used to identify opportunities and upside potential within the produced reservoir. Production optimisation and infill drilling opportunities can therefore be defined maximizing overall field recovery.
This masterclass will use the J-Block production experience as an example to demonstrate how PVT data has been used to both understand well performance and to help identify potential production issues, such as liquid loading. Having a good understanding of individual well performance and issues can help define production improvement opportunities leading to excellent field recovery through an optimised production strategy
Core samples offer us the best opportunity to examine actual reservoir material.
Acquiring cores is frequently time consuming and therefore expensive such that the coring programme is often the first casualty of cost cutting on a project. Unfortunately when cores are taken, the handling and transfer of the cores from the wellsite to the lab can often be neglected and corners cut.
Without core material, which has been collected undamaged by the drilling process, carefully brought to surface, handled properly at the wellsite and analysed appropriately in the lab, geological interpretations based on seismic models will remain unproven, wireline logs will remain uncalibrated and reservoir engineering assumptions on wettability and relative permeabilities will remain unchallenged.
The workshop will briefly review how cores are taken, the best practices for core recovery, well site core handling, monitoring shipping to the lab and the planning of various analyses which are all needed to maximize the useful formation evaluation information that can be extracted from this priceless resource.
Examples of Applied Petroleum Geochemistry; from Health & Safety to Prospect Evaluation
Petroleum geochemistry can be applied to a wide range of issues ranging from evaluating new exploration opportunities to assisting in production problems. High quality laboratory facilities provide the necessary platform and tools to tackle a surprising number of problems encountered by engineers and geologists.
Our presentations will attempt to illustrate some of these by presenting real applications focused on North Sea issues; all due effort will be made to keep this in technical but non-specialist language!
Part 1: We’re forever blowing bubbles! Sampling, Analysing and Verifying Production Facility Integrity.
• Gas bubbles – biogenic or thermogenic? (…or is it hydrogen, or nitrogen?!). Depending on where it’s coming from either no problem or … oh dear!
• Practical aspects of sampling; seabed (ROV), platform (Heath Robinson).
• Analysis – gas composition and isotope ratio analysis, and what the data tell you.
Part 2: Are we going to find nice oil or treacle? Predicting Oil Quality in North Sea Tertiary Plays.
• Biodegradation of oils and oil quality – examples and crucial factors.
• Hydrocarbon generation of the kitchen with respect to thermal history of the migration pathway – 3D models.
Part 3: How Did That Work? Hydrocarbon Geochemistry vs. Pressure Plots.
• Distinguishing between separate reservoir compartments – even when the pressure plots seem to indicate a single column!
Interactive Session with Chris Flavell
We’re clearly in the midst of difficult times in the Geoscience profession at present, although maybe the first green shoots of oil price recovery are becoming apparent.
In such uncertain times, and with so many excellent and highly qualified geoscientists facing redundancy, taking the opportunity to maximise one’s chances of landing that crucial job becomes even more critical.
So what can you do to shorten the odds, to put yourself in the very best possible position? The following fundamentals are equally applicable in times of growth as in times of recession, the only difference being the greater competition for far fewer roles in the latter.
We’ll discuss each of these points in more detail during the session, but the broad topics will be:
• CVs – how to ensure you get all the relevant information concisely and articulately into your CV
• Interview technique – including pre-interview preparation
• Skills broadening – where are your skills gaps, and what should you do to try to fill them, whether currently in or out of work?
• Further qualifications – weighing up the balance between improving those chances vs staying without income for a period
• Oil Companies vs Integrated Consultancies vs Service Companies – if from an oil company background, don’t disregard the Consultancies and Service Companies. Historic salary imbalance is reducing, and you can gain very valuable, CV-enhancing experience in both
