Shale developments are being aggressively pursued and developed in North America and are rapidly being tested in other parts of the globe. These mudstone formations, while similar in many ways, possess unique rock and fluid properties. Further variability is introduced by the natural geologic and reservoir heterogeneities present within each specific formation. Multizone hydraulic fracturing and completion designs that address the formation variability at both the macro and micro-scale, can enable improved resource recovery. Reservoir understanding, through formation evaluation (FE), coupled with efficient, reliable and cost-effective completion methods, enable continuous improvement for shale developments.
Mineralogy, organic content, geomechanical setting, diagenetic history and other factors, influence how the rock will respond to a particular hydraulic fracture stimulation treatment. Stimulation treatment chemistry, rate, proppant type and volume are tuned to a particular shale play and ultimately a field in order to maximise production and lower cost per BOE. Completion design factors (e.g. well placement, lateral length stage spacing, lateral hardware, treatment diversion method, reservoir entries, etc.) have also evolved to improve stimulation efficiency, maximising Stimulated Reservoir Volume (SRV) and ultimately improving well economics.
Variability of rock properties within a shale stratigraphic section, or along a long length of lateral wellbore, is often neglected when designing stimulations or completion techniques. The pursuit of improved economics using high density well development approaches has pushed the industry to generalise the rock properties and apply standardised designs and operations. While such techniques can improve completion installation efficiency and reliability, a more thorough understanding of rock properties of each well may improve well/stage placement, completion technique and production and ultimately lead to lower cost per BOE produced.
Unique drilling, completion and fracturing techniques are also evolving to take advantage of improved reservoir understanding while still improving overall completion efficiency and maintaining the high density well development approach to shale development. This workshop will explore methods for geological, petrophysical and reservoir understanding of shales, coupled with unique, engineered approaches to multi-zone proppant fracturing and completions, in order to optimise shale development economics.
The workshop is aimed at the following:
Two-and-a-half days of informal sessions, with a number of short presentations, breakout discussions. There will be an evening welcome reception on Monday 1 October and dinner on Wednesday 3 October. Full details will be provided with the joining instructions which will be sent in September.
75-85 delegates from relevant disciplines with proven experience and/or knowledge of the subject areas being covered.
The workshop qualifies for SPE Continuing Education Units (CEU), at the rate of 0.1 CEU per hour of the workshop.
The steering committee will appoint a scribe to make a full report of the workshop, summarising all presentations and discussion. This report will be circulated to all attendees. The copyright of the scribe’s report will belong to SPE.
All attendees will receive a certificate from SPE confirming their participation.
Written notice received 30 days before the starting date of the workshop entitles registrants to a 50% refund. There will be no refund for cancellations received after this time but alternative delegates will be welcomed.
