Session 2: Panel Session: Slim Wells – Surmounting the Obstacles
Moderator(s) Malik Faisal Abdullah, PETRONAS; Zahris Sham Abu Musa, Schlumberger

This panel session will discuss what it takes to make slim hole drilling and completions more acceptable and prevalent in Malaysia. Obstacles and challenges related to safety, risk management, contingency requirements, regulations and hydrocarbon extraction will be discussed and deliberated. The focus will be on exploring the opportunities and ideas that can maximise exploration and development wells cost savings.

12:00 - 13:00
13:00 - 14:30
Session 3: Subsurface Insights to Slim Hole Drilling and Development
Session Chairpersons Padsakorn Suwanruji, PTT Exploration and Production Public Company Limited; Ahmad Razien Liyackat Ali, Halliburton

This session will encourage discussions that are challenging and have potential value-add by shifting towards the unconventional ways of slim hole field development. Sharing best practices from the perspective of subsurface experts, it will stimulate discussions on critical elements including effective reservoir management that would greatly impact the success of slim hole drilling and development applications.

14:30 - 14:45
14:45 - 16:15
Session 4: Slim Hole Drilling Solutions
Session Chairpersons Vethiah Srimugayogam, Baker Hughes, a GE company; Adrian Robert Young, Murphy Sarawak Oil

This session will focus on the challenges of drilling slim holes. Working with reduced operating parameters due to physical tool and bit limitations to optimise the rate of penetration (ROP) will be a challenge to justify the economics of drilling slim hole. 

Managing the Equivalent Circulating Density (ECD) and hole cleaning are riskier in the slim hole environment. The availability of limited tools especially advanced formation evaluation tools and their reliability, might be a concern for the subsurface team. Contingency planning poses additional obstacle as the borehole is already slim. Mitigations for the challenges and risks will also be discussed in this session.

16:15 - 17:45
Session 5: Breakout/Poster Session

Session 6: Case Studies: Exploration Drilling and Testing
Session Chairpersons Noorazmah Yusoff, PETRONAS Carigali Sdn Bhd, Mohd Hafiz Mohd Makri, PETRONAS Carigali Sdn Bhd, Fauzi Abbas Abbas Shariff, Vestigo Petroleum Sdn Bhd

Slim hole drilling and testing may be the easiest way to attain cost savings when reservoir management and production are always of concern. This session will demonstrate how some companies saved millions of dollars by simply reducing the borehole sizes and cased-off with smaller sized tubulars and reduced number of casing strings. As exploration often deals with huge subsurface uncertainties, additional smaller hole size is always planned as a contingency. Slim hole testing is also an area that requires careful planning. This session will address those issues and the mitigation aspects that has taken place without compromising HSE and wells or operation integrity.

11:00 - 11:15
11:15 - 13:15
Session 7: Completions and Interventions Solutions
Session Chairpersons Jennie Pui Ling Chin, Schlumberger; Le Lola Dang, Baker Hughes, a GE company

This session will focus on various well completions and interventions solutions in slim hole completion environment for both open hole and cased hole. Solutions including sand control methods, future intervention strategy, slim hole completion accessories not limited to gas lift mandrels, packers and inflow control devices will be covered. The successes and failures and lessons learnt will also be shared to enable better planning and more faultless execution.

13:15 - 14:15
14:15 - 16:15
Session 8: Case Studies – Development Drilling and Completions
Session Chairpersons Norjusni Omar, PETRONAS; Muhammad Fadzli Abdul Rahim, Baker Hughes, a GE company

This session will illustrate slim hole drilling and completion techniques that will contribute towards meeting the slim hole well objectives. Case studies include new technology application, experiences, lessons learnt, limitations and challenges faced in various phases i.e. planning, engineering, operations and intervention/workover. The experience and knowledge sharing in these case studies are very valuable and beneficial for new projects aiming to utilise this proven concept.

Drilling and completion well designs play important roles to achieve slim hole and fit-for-purpose well objective for a development project. Although the cost may always be the driver, other considerations on well design and techniques need to be taken into account in order to ensure well integrity, safety, flexibility, accessibility, and more, would not be jeopardised.
