据油气杂志网2019年10月31日报道，总部设在瑞典的特提斯石油公司(Tethys Oil AB)通过其旗下子公司特提斯石油阿曼陆上有限公司将以现金形式支付多达950万美元与Biyaq油田服务公司签署购入权益协议，根据协议，特提斯石油公司将获得覆盖位于阿曼海上第56号区块的勘探和生产许可证20%的权益。
第56号区块位于阿曼东南部，面积5808平方公里，在第3号和第4号区块以南大约200公里。第56号区块迄今共钻了11口井，其中3口井由Medco 阿拉伯有限公司负责。除一口井外，另外10井都钻遇到了石油或石油显示。没有一口井被确定是商业性的。目前正在编制3口井的流量测试工作程序。
第56号区块位于不同地质省的交汇处，包括南阿曼含盐盆地。特提斯石油公司表示，这个盆地在多个远景区提供了勘探潜力，包括探明和未探明的。
第56号区块最初的3年勘探和产量分成协议于2014年11月签署，后被延长至2020年12月。可以选择将于2023年12月结束的第二阶段勘探。
交易完成后，第56号区块的权益分配为运营商Medco 阿拉伯公司50%、Intaj LLC 25%、特提斯石油公司20%和Biyaq油田服务公司 5%。

Tethys Oil farms in to Block 56 onshore Oman
Tethys Oil AB, through subsidiary Tethys Oil Oman Onshore Ltd., will pay up to $9.5 million in a cash and sign farm-in agreement with Biyaq Oil Field Services for 20% interest in the exploration and production license covering Block 56 onshore Oman.
Block 56 covers 5,808 sq km in southeastern Oman some 200 km south of Blocks 3 and 4. Eleven wells have been drilled on the block, three by operator Medco Arabia Ltd. All but one of the total wells drilled have encountered oil or oil shows. None have been determined to be commercial. A work program to flow test up to three wells is being prepared.
The block lies at the intersection of different geological provinces including the South Oman salt basin. It offers exploration potential in multiple play concepts, both proven and unproven, Tethys Oil said.
The initial 3-year exploration and production-sharing agreement for the block, signed in November 2014, was extended to December 2020. A second exploration phase, ending in December 2023, is optional.
Interest in Block 56, upon completion of the transaction, will be operator Medco Arabia Ltd. 50%, Intaj LLC 25%, Tethys Oil 20%, and Biyaq 5%.
