PDO shifting from EOR to lower-cost production methods

March 22, 2016
Petroleum Development Oman (PDO) said enhanced oil recovery (EOR) is expected to account for about 25% of its oil production by 2025, vs. last year’s projection of 33% by 2023.

Petroleum Development Oman (PDO) said enhanced oil recovery (EOR) is expected to account for about 25% of its oil production by 2025, vs. last year’s projection of 33% by 2023.

PDO operates several EOR projects, including chemical EOR, miscible gas injection, and thermal applications. But due to lower crude prices and the resource-intensive nature and higher cost of tertiary recovery mechanisms, PDO is placing more emphasis on accelerating conventional oil and gas opportunities instead of short-term expansion of EOR projects.

PDO said 2015 crude oil production of 588,937 b/d was the highest since 2005. Combined production of crude oil, natural gas, and condensate averaged 1.29 million boe/d, which PDO said was a record. Of that total, gas production contributed 83 million cu m/day. PDO accounts for about 70% of Oman’s crude oil production and nearly all of its natural gas supply.

In a report on 2015 results, PDO said it made an oil discovery at Sadad North in southern Oman that resulted in 44.5 million bbl of commercial contingent reserves.

A gas discovery at Mabrouk Southwest provided 0.38 tcf of commercial contingent reserves. It’s a satellite to Mabrouk field in the northern part of PDO’s Block 6 concession area (OGJ Online, Nov. 19, 2015; Apr. 3, 2013).

A discovery in Tayseer gas field in southern Oman added in-place volumes of 0.93 tcf of gas and 117 million bbl of condensate, PDO said.

The company also noted that ground-clearing is complete on the 3-sq-km Miraah solar energy project (OGJ Online, July 9, 2015).
