Abstract:

The Permian Basin is one of the prolific hydrocarbon-producing regions in the world, containing numerous vertically stacked producing intervals. Off late, operators are moving into “factory/tank”-style field development strategy to optimize production. However, the geology presents some unique challenges ranging from rapidly changing geology, presence of thin-bed, to variable pore pressure gradient. Failing to address these challenges may lead to significant uncertainties in petrophysical evaluation, well interference and ultimately impacting producibility. High-performance computing and advanced analytical techniques permit operators building high-quality geomodel via integrating field measurement, seismic and sonic data, and core measurement. The quality of core based geomechanics and petrophysical measurement is not only crucial for success of modeling effort but also for better understanding of the hydraulic fracturing process, fluid flow behavior, well and stage placement and landing target identification. This talk highlights some key core-based measurements to understand permeability and its variation with stress, mechanical and poroelastic behavior of rock and variability of insitu horizontal stress.

We begin with introducing technique for measurements of matrix and fracture permeability. We present results on samples obtained from Permian and other producing reservoir and how they are impacted by fabric and composition. We also present a recently developed method to clean the plug to obtain the absolute matrix permeability. Following this, we briefly touch upon static and dynamic mechanical property measurement that honors reservoir heterogeneity and anisotropy. We then demonstrate how the measurements can be scaled up to build a well-centric geomodel including insitu stress profile. Finally, we identify the importance of poroelasticity in hydraulic fracture design and present a laboratory technique for measurement of poroelastic coefficient. We conclude with presenting an example of well-centric geomodel building for the region.

Abstract:

Realistic and rapid workflows for acquiring lateral log-type data from cutting samples

With the continued importance of enhancing production from unconventional plays there is an on-going need to acquire petrophysical data from laterals wells. Traditionally, such data are acquired using lateral-logs, but in the factory-drilling mode of the unconventional plays today, running logs in laterals is prohibitive in terms of cost and time. However, the type of data logs provide are still needed, but they need to be gathered quickly and without significant additional cost – how to achieve this?

The workflow outlined here measures mineralogy, TOC, RHOB, RHOM and porosity, thereby enabling calculation of rock mechanical moduli. These data are gathered on cuttings samples that have been linked to MWD Gamma to ensure formation representivity. The advantages of this approach are low cost and low risk, but clearly the disadvantage is the lower resolution than comparable data from logs.

The presentation graphically demonstrate the workflow from receipt of sample, though preparation and analysis to output and integration will be graphically demonstrated. Examples of output from the Permian Basin will be shown, together with comparisons to the same data gathered in more traditional ways.

Lateral-log type data from cuttings samples in lateral wells are provided within days at a fraction of the cost of running logs and without the associated risks and logistics. Therefore, it is a realistic and real alternative to running logs that provide fit-for-purpose data.

Biography:
Milly has spent the last 15+ years working the field of chemostratigraphy and bulk elemental analyses, and as Director of Operations for Chemostrat Inc, in Houston has studied elemental datasets and their interpretations in wide variety of depositional environments and plays all over the world. Milly is originally from the U.K. and graduated with her undergraduate degree in geology from the University of Leicester in 2000, she then completed her master’s degree in geology from University of Houston in 2010. Her graduate research largely focused on identifying facies and provenance changes using an integrated chemostratigraphic and sequence stratigraphic approach in the Ferron Sandstone, Utah. Over the last few years Milly’s research has predominantly focused on resource plays, regularly presenting at local and national conferences. Outside of work Milly spends her time on the dance floor and is an experienced ballroom and latin dancer.
