Exploration and Assessment

No Two Shales are Alike
Many shale gas reservoirs have been previously thought of as source rocks. New shale developments find these source rocks still contain large volumes of hydrocarbons that can be produced using latest horizontal drilling and hydraulic fracturing technologies. There are over 200 source rock basins around the world. Lithology, maturity characteristics and production profiles vary significantly both within and between shale plays. Halliburton Consulting has a consistent and replicable screening and ranking methodology to help clients to equitably evaluate unconventional opportunities.   

Using the screening and ranking methodology, Halliburton Consulting can help you:

  • Rapidly eliminate opportunities of low commercial value.
  • Efficiently and inexpensively characterize, analyze, and high-grade highly prospective acreage.
  • Support / refute comparisons of the US resource plays to international opportunities, for use as analogues in your development strategies .
  • Apply best practices / lessons learned from relevant US analogues to optimize your drilling and completion strategy. 

What Makes a Good Play in Shales

It is very important to quantify the minimum geological characteristics necessary to develop a viable unconventional play - the thresholds  below which the probability of success for delivering economic production levels is low.  We use seven geological parameters as a first-pass screen:  area (square miles/kilometers), average depth, net thickness, total organic carbon content, maturity, brittleness and gas-in-place.  Once a play has met the minimum characteristics, the distribution of the shale properties will have important economic and operational ramifications in the areas of well spacing, well treatment, and fracture design.

Finding the “Sweet Spot”

Shale plays often stretch for thousands of miles. The experience in US shales confirms that these basins are far from homogenous.  Changes in geological conditions, rock facies distribution and mechanical properties can happen as often as every 100 feet. Hence the disparity in the success of wells drilled right next to each other and using similar completion technology.  Halliburton Consulting can help you acquire, analyze and correlate all structural, petrophysical, geomechanical, rock type, and historical production information you have about your reservoir. We can then build an integrated asset model to give you a full view of its most prospective areas in an environment where geoscientists and engineers can collaborate.
