A survival guide for digital transformation

When organizations everywhere are racing to embrace Digital Transformation, it is easy to get excited about the claimed possibilities and to overlook the fundamentals. It is also unclear what this will mean for most of us, our organizations and employment prospects. Hence it is reasonable to ponder and assess our readiness for these changes and the opportunities they may bring. Digital Transformation arguably began a long time ago. It was in the late 1980s that just about everyone in the oil and gas industry started using computers. These were first introduced as “productivity tools” in support of conventional work. With the benefit of experience and technological progress, organizations have evolved new workflows. Today, Information Technology projects are increasingly seen as corporate gamechangers.

In this lecture, an experienced geoscientist offers his take on what Digital Transformation may mean, and suggests how to prepare to ride the wave and succeed. Specific topics will include the need for a reliable data inventory, pre-requisites for the integration of multiple data sets and for the rigorous quantification of uncertainty. All these can be implemented without disruption, at low incremental cost and great potential value to all parties. The main takeaway point is that regardless of what Digital Transformation turns out to be, some actions should be taken now rather than later to ready the organization. These actions all revolve around the systematic consolidation of specific data fundamentals. In the process, the people involved will also become better prepared and more valuable to their organization.

Petrophysical rock typing: An integrated approach to reservoir characterization

Rock typing is an essential tool used to distribute reservoir rock and fluid properties in reservoir models. It provides accurate estimation of reserves during field studies and predict reservoir performance. These are the required inputs for static and dynamic models to populate porosity, permeability, and shale volume which influence reservoir productivity.

In this study and lecture, a few Rock Typing approaches were investigated that include Hydraulic Flow Unit (HFU), Global Hydraulic Elements (GHE), Winland R35, and Traditional Density-Neutron using core data to produce relationships that tie together pore geometric attributes, pore structures, and hydraulic flow characteristics. It was observed that Hydraulic Units (HU) concept among others was robust in Rock Typing based on consistencies established on porosity-permeability relationships in typical clastics. Hydraulic unit concepts reconcile hydraulic conductivity with geological concepts through employing RQI and FZI on core data. Consistency in saturation height modelling constructed from capillary were matching the HU classes generated on the permeability – porosity cross plots.

Reservoir Monitoring and Management with Inflow and Interwell Tracer Technology

This lecture demonstrates how inflow and inter-well tracer technology can provide key information required for effective production and reservoir monitoring and management.  

Inflow tracer technology is a wireless, risk-free, and cost-effective monitoring solution for continuous production monitoring. The technology consists of unique tracer molecules embedded into polymer systems. Tracer systems can be integrated with any type of completion, and they are distributed along lower completion to provide zonal resolution throughout well life. Once installed, water and hydrocarbon-sensitive tracer systems release their embedded tracers when they are in contact with their target phase therefore, the distributed tracers carry important information about inflow contribution of different zones continuously and on demand. The information includes cleanup and stimulation efficiency monitoring, water breakthrough monitoring, quantitative zonal productivity assessment, and completion integrity monitoring. 

Inter-well tracer technology is the reservoir surveillance method that offers more than connectivity through the reservoir and is essential to optimize recovery. Unique water or gas tracers can be pumped into injector(s) to trace the injected fluids in reservoir and thereby provide tangible reservoir information about flow paths and injector-producer connections, sweep volume, flow allocation, and remaining oil saturation.

Real-Time Drilling Optimisation for Well Cost Reduction - 16th June 2022

This lecture reflects the highly sought-after modern topic of “Real-Time Drilling Optimisation for Well Cost Reduction”, which is applicable to both Oil & Gas and Geothermal wells.

It provides insight into data-driven answers to important questions such as: “How could we optimise escalating Drilling Costs?” or “ Why drilling costs are high with no obvious operational problems?”. Unfortunately, there are “no” short & easy answers when it comes to saving on drilling costs. Saving millions in wells drilling costs, could not be achieved with the team’s experience alone and hence the need for Real-Time Drilling Optimisation which could be truly a game-changer for traditionally expensive wells.

This lecture shares expert knowledge and effective workflows related to data-driven drilling execution, which have delivered great savings to a variety of global operators.

Production Well Design: Think Well Integrity and Well Decommissioning - 26th April 2022

Oil and Gas (O&G) is a special business in which we operate close to vast supplies of hazardous substances. Being willing to deal with such potentially dangerous substances in a safe and environmentally friendly way is essential to the sustainability of this business. 

Wells are the most critical element of the asset as the possible effects of a well failure can be disastrous. Loss of wellbore integrity is a well-understood and chronic problem. Drilling companies emphasize well integrity because a faulty well is expensive to repair and, in the rarest of cases, costs lives, as in the Deepwater Horizon disaster in the Gulf of Mexico. Well Decommissioning is a costly challenge, and for many countries, the value at stake in handling decommissioning projects properly could be worth several billion dollars. While it may not seem to be that important on new projects like Tilenga and Kingfisher in Uganda, there is a massive opportunity to design wells for ease of decommissioning.

This lecture explains some of the principles of Well Integrity and Decommissioning. Both are the critical phases of the Well lifecycle that require special attention during the well design and construction stage.

United Nations Framework Classification for Resources: General Principles and its Application to Petroleum Projects - 6th April 2022

The United Nations Framework Classification for Resources (UNFC) is a resource project-based and principles-based classification system for defining the environmental-socio-economic viability and technical feasibility of projects to develop resources. UNFC provides a consistent framework to describe the level of confidence of the future quantities produced by the project.

Developed under the auspices of United Nations Economic Commission for Europe (UNECE), UNFC is designed to be universally application to different energy sources including solar, wind, geothermal, hydrocarbons, injection for storage etc. through a principles-based system in which the products of a resource project are classified on the basis of the three fundamental criteria of environmental-socio-economic viability (E), technical feasibility (F), and degree of confidence in the estimate (G), using a 3-dimentional numerical coding system.

This lecture explains the general principles of UNFC, illustrates its application to petroleum projects using a case study in comparison with Petroleum Resource Management System (PRMS) and presents a SWOT analysis on its use.
