Alliburton: Swot analysis and evaluation of competitivebusiness-level strategies

i am in a group at school where we are performing a case analysis of Halliburton company. We are doing a group powerpoint presentation. during the presentation I have to discuss:
1) an evaluation of their Strengths, weaknesses, opportunities and threats. I have to identify distintive competencies, analysis of the potential for sustained competitive advantage, balue chain analysis.I think 1 to 1-1/2 pages should allow me to briefly discuss these topics.
2)Evaluation of competitive business-level strategies. I have to discuss cost leadership, product differentiation, and focus/niche (may also include core competency)–I think 2 1/2 to 3 pages should allow me to briefly discuss these topics.
My group is focusing on the energy/oil side of Halliburtons business but, I realize my topis may need a glance at the other aspects of their business.
