INTRODUCTION   LEMIGAS Core Laboratory   Provides a full range of core analysis, and related services such as reservoir geology and reservoir engineering studies. In conjunction with the other LEMIGAS Engineering Division, we offer clients a single and integrated source of geological and engineering data used in the development and management of Petroleum Reservoirs. We are proud of our hard won reputation for global service and technical excellence, and strive to deliver the greatest value on every project no matter how big or small.         • Wellsite Services         Lemigas Core Laboratory is equipped with both reliable equipment and experienced manpower to provide a wide range of services at the wellsite. Our services begin in our client's office, where an efficient coring program starts with good planning and identification of formation evaluation problems to be solved. Our experience allows us to aid in the development and implementation of a core handling and core analysis program on a broad range of evaluation projects. Core handling and preservation prior to the arrival of the core at laboratory is absolutely crucial to the success of a rock characterization study. Mishandling of core can invalidate even the most carefully designed laboratory test.        Our services in core handling include :     » Core catching and preservation     » Core slabbing and packing         » Core resination         » Core photography (white light and UV)         • Routine Core Analysis     Lemigas services in routine core analysis span from core preparation to core plug analysis such as porosity, permeability and fluid contents. For the purpose of core sample flexibility, Lemigas employs its own core image system for digital recording, storage and retrieval of core photos.        Our services include:       » Surface core gamma       » Spectral core gamma       » Digital Core Photography       » Core photography       » Core slabbing and boxing       » Conventional core analysis       » Full-diameter core analysis       » Sidewall core analysis       » Fluid contents analysis           • Special Core Analysis         Special Core Analysis complement basic routine core data, and furnishes information that allow calculation of static fluid distribution and dynamic flow performance of a well or reservoir.        Our services include:         » Porosity at confining pressure » Rock-fluid compatibility     » Permeability at confining pressure » Capillary pressure testing     » Pore volume compressibility   » High-speed centrifuge capillary pressure     » Steady-state relative permeability » Wettability     » Unsteady-state relative permeability » Acoustic velocity     » Electrical properties measurement » Cation exchange capacity     » Waterflood susceptibility   » Mercury injection (60,000 psi)         • Sedimentological Services         The primary objective of this services is to evaluate depositional environments, mineralogy/rock composition, reservoir quality, sensitivity to drilling and completion fluids and the potential and possible mechanism of formation damage.        Our services include:         » Lithologic core description and environment interpretation     » Thin section photomicrograph       » Thin section preparation at confining pressure     » Thin section description and modal analysis     » Fluorescence microscopy       » Scanning electron microscopy/energy       » Dispersive X-ray spectrometry       » X-ray diffraction         » Data interpretation         » Well completion prognosis       » Hydraulic flow unit identification       » Diagenetic studies         » Rock typing         » Facies analysis and sequence stratigraphy
