Dear Member,

After a thoroughly enjoyable summer break LPS resumed evening

meetings last week with an excellent double bill of talks from Ahmed

Badruzzaman Ph. D, ANS Fellow Pacific Consultants and Engineers and

University of California, Berkeley and M. M. Aliyu of University of

Leeds. Ahmed gave us a fabulous talk titled “Alternative Nuclear-

based Technologies to Mitigate Risks of Radionuclide Well Logging

Sources: Their advantages and challenges” while Aliyu gave a talk

titled “Physicomechanical Characterisation of Flint: Variation and Control Perspectives”. Both talks prompt-

ed healthy debate and discussion. The evening meeting was well attended by students and experienced

professionals alike.

It was particularly exciting to see back to back presentations from an SPWLA Distinguished Speaker and a

LPS grant award recipient. We are very appreciative of the support from SWPLA in supporting travel costs. It

very much helps access to great speakers and allowed Ahmed to travel on to Aberdeen to present at AFES.

I want to remind you that it is not too late to get your registration in for the next one day seminar to be

held next week on Thursday 24th September. At a time of cost cutting, this seminar will be of interest to

petrophysicists, geologists, reservoir engineers, geophysicists, technical assistants, and support staff work-

ing directly with or looking for a refresher on legacy data, applying new tools/techniques to vintage data,

frontier exploration and research integrating complex datasets. The title is “Old data, New tricks: Fresh chal-

lenges, Mature targets, and Scientific oddities” and is being run in collaboration with U.K. International

Ocean Discovery Program (IODP). Please visit the website for more details and registration forms.

The next evening meeting will be held on 20th October where we have yet another SPWLA Distinguished

Lecturer to offer you. Mark Proett from Aramco Services Company will present a talk titled “Automatically

Quantifying Wireline and LWD Pressure-Test Quality”. Talk starts at 18:30hrs in the Geological Society as

usual. Free entry and no registration necessary.

Volunteers Needed! We are starting to look forward to our Annual General Meeting on Tuesday 17th No-

vember where we will present the LPS 2015 Executive Committee for the approval of the membership.

The Committee will need additional help in 2016, so if you would

like to volunteer some of your valuable time to assist in the running

of the LPS, our Past-President, Mike Millar, would really like to hear

from you (mike.millar@bg-group.com, 0118-929-3404).

I look forward to seeing you at some of the events above.

Best Regards

Iain Whyte Iain Whyte : LPS President

The LPS is run by the Executive Committee, a group of volunteers from Industry and Aca-

demia, and we are looking for people to join us for 2016 and beyond. Executive Committee

meetings are held at Burlington House before the evening Technical meetings, and some of

the Committee work is also done via email. So if you would like to volunteer some of your

valuable time to assist in the running of the LPS, please get in touch with Mike Millar (Past-

President) by 15th October (mike.millar@bg-group.com, 0118-929-3430, http://lps.org.uk/

Abstract— Upcoming Evening lecture Automatically Quantifying Wireline and LWD Pressure-Test Quality

Thursday 20-Oct-2015

Presenter

Mark Proett is a Sr. Petroleum Engineering Consultant

for Aramco Services Company, Upstream Group in Hou-

ston. Mark is best known for his publications advocating

the viability of the formation testing-while-drilling

(FTWD), introduced in 2002, with the Sperry GeoTap

service. He has been awarded 54 US patents and au-

thored over 50 technical papers, most of which deal with

sampling and testing analysis methods. He has been an

SPWLA Distinguished Speaker and SPE Distinguished

Lecturer. In 2008 Mark received the SPWLA Distin-

guished Technical Achievement Award and in 2013 the

SPE Gulf Regional Formation Evaluation Award. Mark

has a Bachelor of Science in Mechanical Engineering

from the University of Maryland and his Master of Sci-

ence from Johns Hopkins University.

Abstract In the literature regarding wireline (WL) and logging-while-drilling (LWD) pressure

testing analysis, theoretical transient models are promoted to evaluate the quality of

pressure test points, typically by a skilled analyst. However, in practice, other crite-

ria are normally used to judge the test quality. Some are ad hoc, but there is a grow-

ing consensus that several convenient, simple, and effective real-time measurements

are needed to evaluate the quality of the test points. This presentation demonstrates

an automated process that was developed where these real-time measurements are

used to determine the validity of the pressure test and a rating assigned based on pre-

determined standards.

The primary measurements made now include the drawdown mobility (md/cp) and

buildup stability (psi/min). Although these measurements can be effective inde-

pendently, they are also a source of information that can be expanded upon to further

analyze the data. For example, how does the pressure stability compare to what is

expected considering the drawdown mobility? Noise in the pressure data caused by

mud flow is particularly evident in LWD pressure testing and the standard deviation

of the pressure data during the buildup is another consideration for test quality. The

radius of investigation can be estimated using the drawdown/buildup times with the

mobility estimate to quantify the testing effectiveness. Supercharging is a concern

for pressure measurements when the pressure measured is influenced by mud filtrate

invasion that has elevated the pressure at and near the wellbore. The supercharge

potential can be determined by making some simplifying assumptions to further

evaluate the data points. These calculations can be made by using basic principles

and will guide the analyst monitoring the test to determine the relative quality of the

test points. In this way, the best quality test points are used in the analysis of fluid

gradients or for integration into the Petrophysical analysis.

Dick Woodhouse Award

Annual prize trophy & cash award (£1000)

The Dick Woodhouse Award to Young Professionals

Guidelines for Submissions Why: To encourage the pursuit of excellence in young professional Petrophysicist and other ge-oscientists involved in formation evaluation. To celebrate the outstanding contribution that Dick made to our industry during his 45 year career. Who: Industry professionals with up to three years industry experience; or researchers (but not MSc or PhD students as they are covered by the Iain Hillier award scheme). Where: UK based companies or research centres, or UK based workers on short/medium term over-seas assignments. What: The annual prize consists of a trophy and a cash award of £1000. How to apply: Qualifying young professionals can nominate themselves, or they can be nominated by a colleague or friend, the submission process is the essentially the same. Submit a conference style poster (or paper) to LPS committee for review. The topic should be an inspiring, original and innovative project or piece of work based on formation evaluation using well bore data such as logs, core, pressures. Integration with other subsurface disciplines is encouraged. Original contributions on theoretical and applied aspects of petrophysics, including both open-hole and cased-hole well logging as well as core analysis. Case histories and interpretation are of special interest. You can submit posters or papers that have been published or are under consideration for publication elsewhere, but please give de-tails. The work can have been done as part of a team and does not have to have been an individual pro-ject.

All material presented will be kept confidential.

The 2016 international symposium will be held in Reykjavik, Iceland. As an industry in change petro-

physicists are responsible for making sure we acquire the right data for our projects. But we must also

demonstrate that value is added to the project through interpretation of high quality, fit-for-purpose data.

Petrophysics is one of the key inputs linking geology into reserves optimization, and in today’s economic

climate with an increasing challenge to find new reserves it is more important than ever to emphasize the

value petrophysics adds to our business.

The SPWLA Board of Directors invites you to join us in Reykjavik, Iceland, June 25-29, 2016 to show-

case your recent innovations and discoveries at the 57th Annual Symposium. We solicit papers on all

aspects of formation evaluation.
