Analysis and evaluation of alternative concepts in modeling tarmats to conform to laboratory investigations and field conditions
- Arabian American Oil Co. (US)
Black-oil reservoir simulators are universally formulated to handle a maximum of three different fluid phases - i.e., oil, water,a nd gas. The phase identify of tar, occurring in concentrations called ''tarmats'' within or marginal to petroleum reservoirs, varies widely from highly viscous hydrocarbon fluid to near-solid material. In black-oil modeling of tarmat reservoirs, therefore, considerable challenge is posed in characterizing tar as a drastic departure from the three fluid phases. No published literature provides concentrated details on tarmat modeling with an emphasis on comparative analysis and adaptability of different state-of-the-art modeling techniques. This paper compares the two approaches adopted most often to characterize tar in a model - i.e., as a highly viscous hydrocarbon fluid and as a relatively impermeable rock matrix. Other less commonly used methods that also may be reasonable are not discussed.
