Technical Agenda

Thursday, 4th December, 0900-1030              

Session 1: Improving Subsurface Understanding

Session Chairs: Salil Banerjee, Shell; R.K. Sharma, IRS

Effective solutions for optimising mature field performance begin with reservoir characterisation. Geophysical, geological, petrophysical, production, and injection data are critically important for understanding reservoir fluid dynamics. Reservoir simulations synthesise these data and form the basis of the analysis for integrated reservoir management. Advances have been made over last two decades in locating and accessing new plays and bypassed oil with advanced logging, 4D seismic, crosswell imaging technologies, 3D geo-modelling, and fine scale numerical simulation. Moreover, EOR techniques are the key to injecting new life in any mature field which require precise understanding of reservoir characterisation.

This session will discuss case studies on integrated reservoir management and innovative ways to improve reservoir characterisation leading to higher recovery.


Session 2: Ageing Facilities

Session Chairs: Jyotisman Dasgupta, L&T; Yash Malik, ONGC

Facilities associated with the production installations of mature offshore oil and gas fields, covering all structures, topside plant and equipment, wells and pipelines, safety critical items, etc., designed to sustain an operational life, gets stretched over usage and time. Changes in process fluids, mechanical wear and tear, corrosion, procedural changes, changing standards, staff knowledge, etc., all contribute to their ageing leading to obsolescence. It becomes essential to increase their longevity with an eye to maintain economical throughput without compromising on safety as per applicable standards. In some cases the facilities may need prior replacement than its estimated life, for reasons such as:

  • Comply with OISD standards, OMR 1984 regulations, any other applicable regulatory changes, etc.
  • Field conditions like increase in water cut/high GOR necessitating replacement
  • Obsolescence due to technological changes
  • Operational philosophy

Addressing these challenges is paramount in maintaining productivity and safety over extended time. This session will not only discuss but also gather past experiences in dealing with ageing facilities. It will also showcase success stories challenges.


Session 3: Innovative Well Engineering

Session Chairs: Debashis Gupta, Schlumberger; R.K. Vij, ONGC

In mature fields, focus must be on finding additional value coupled with reducing life cycle costs. New technologies promise much in realising these aims but must first be successfully implemented. In particular, multi layered reservoir fields need much more innovative design and well completion technologies. Implementation of these technologies in mature fields often poses significant integration challenges with the existing field infrastructure.

This session invites contributions on applications of viable techno-commercial technologies related to innovative well engineering covering aspects of well design and construction together with intelligent well technologies capable of downhole measurement and control of well bore and reservoir flow.


Session 4: Break-out Session

Session 5: Advances in IOR/EOR

Session Chairs: Shyamal Bhattacharya, ONGC Videsh Limited; Rich Paces, Cairn

Today more than 85% of world oil production comes from old and mature fields that are in a declining stage. Most oil producing companies are looking for various means to arrest the decline of their mature fields, augment production, and improve recovery. In order to accomplish this, operators have embarked on implementing several techniques in the form of IOR/EOR. Enhanced oil recovery (EOR), also referred to as improved oil recovery (IOR), although the later has broader meaning, is most often achieved by injecting a liquid or gas into an oil reservoir, thereby either lowering oil viscosity or reducing the mobility ratio between the flooding fluid and the in-situ oil thereby increasing the amount of oil recovered. Some of the more common EOR methods include gas EOR (mostly CO2), thermal EOR, and chemical EOR. While only about 10%–30% of the oil initially in place is typically extracted from a field by conventional depletion and water flooding processes, EOR can enhance recovery by an additional 5% to 20%. Around the world, IOR/EOR applications are growing and metamorphosing to fit the specific requirements of mature fields as well as other local factors, such as the health of the local economy; the level of foreign investment; existing politics and policies that may hinder or spur investment; available technological
knowledge and expertise; the type of oil being produced; the geographical location of oil fields and the geology of oil reservoirs; as well as regional oil supply and demand.

A plethora of IOR/EOR technologies and processes are emerging and becoming available to fulfill these requirements and ease declining production for many operators.

A paradigm shift is also taking place with operators now looking to implement EOR solutions earlier in the life of their fields to improve recovery, accelerate production, and maximise the value of their assets. This session will focus on some of the proven EOR technologies being applied today as well as on some of the advances being made and emerging technologies.


Session 6: Production Enhancement Through Technology

Session Chairs: Anwar Husen, Cairn India and Manav Kanwar, SK Oilfields

"Technology is one of the most important drivers of value in the E&P industry today. Effective, fit-for-purpose processes to implement technology can have significant positive impact and provide major competitive advantage but they must fit seamlessly with the available resources and organisation of a company.

Essential to effective technology deployment are : A clearly defined and understood business need; a well articulated value proposition; strong and consistent end-user involvement (including top management drive to deploy the technology); supplier skills to develop and apply the technology; and effective risk management.

This session invites contributions on applications of technologies (drilling, chemical, well intervention, etc) that have resulted in enhancement of production."


Session 7: Break-out Session
