Chevron Polska Energy Resources Sp. z o.o. ("Company") intends to award one or more non-exclusive core handling, stabilisation and laboratory analysis framework agreements required for Company’s shale gas program in Poland. Economic operators must be in a position to provide the services as and when required by Company.
Call-offs against the framework will be issued to the provider with the most economically advantageous framework agreement and Company will use the same award criteria as stated in the framework agreement invitation to tender.
Only where the terms laid down in the framework agreement are not complete enough for a particular call off, will Company hold a mini competition with all the providers awarded a framework agreement and capable of meeting the particular need against the terms and conditions of the agreed framework agreement.
Company will only consider economic operators with the technical ability and demonstrated experience necessary to service coring operations in central/eastern Europe and to perform laboratory analysis on shale reservoirs.
Economic operators must be able to provide both or either:
1. Wellsite Core Handling, stabilisation and transportation.
2. Laboratory Analysis of reservoir material (whole core, side-wall cores and drill cuttings)
The work scope for core handling shall include, but may not be limited to the following services:
1. Stabilisation of core at well site, including personnel and materials
2. Cutting of whole core into shorter lengths
3. Plugging and preservation of horizontal or vertical plugs at wellsite
4. Recording of hand-held gamma-ray
5. Preservation and packaging of core samples
6. Containerisation and transportation of core to laboratory
7. Collection of gas samples from core plus desorption measurements
The work scope for laboratory analysis shall include, but may not be limited to the following services:
1. Spectral core gamma
2. Fracture & sedimentological description
3. Core photography (white light & UV)
4. CT scanning
5. Slabbing & plugging for routine & special core analyses
6. Routine core analysis using techniques suitable for low permeability shales
7. Geochemistry (TOC, rock evaluation, vitrinte reflectance)
8. Shale petrology & mineralogy
a. Scanning electron microscopy (SEM)
b. Quantitative X-ray diffraction (QXRD)
c. Thin section petrography (including ultra-thin sections, if available)
d. High-pressure mercury injection capillary pressure (MICP)
9. Gas adsorption & desorption isotherms
10. Rock mechanics testing using appropriate methods for shales
a. Geomechanical properties
b. Proppant embedment
c. Capillary suction time (CST)
d. Fluid-shale interactions under stress
Economic operators must have proven experience and demonstrated track record in core analysis relating to tight rock / gas shale reservoirs and must be available to begin services no later than September 2011.
