TAG Oil 开始在埃及 BED4-T100 水平井回流

2024 年 4 月 25 日

(WO) — TAG Oil Ltd. 已在埃及的 BED4-T100(“T100”)井位成功泵送了多级水力压裂的所有十二个计划阶段。

第一至第三阶段位于井的严重裂缝和渗透性较高的部分,接受浓酸增产,而第四至十二阶段则采用支撑剂进行机械压裂增产。

在机械支撑压裂阶段,每阶段至少使用 50 吨沙子,并成功地将超过 1,000,000 磅的沙子泵送穿过 308 米的横向部分。

压裂设备已移离现场,连续油管装置正在钻出用于分隔压裂阶段的球座,随后将在接下来的几天内进行回流作业。

TAG Oil 的技术团队预计大约需要 7-10 天的回流时间才能看到稳定的清洁油流。预计在达到稳定的产油量后大约 10 天,流量将达到稳定。因此,公司预计能够在 5 月份的某个时间发布 T100 油井的流量。

TAG Oil commences flow back on BED4-T100 horizontal well in Egypt

April 25, 2024

(WO) – TAG Oil Ltd. has successfully pumped all twelve planned stages of its multistage hydraulic frac on its BED4-T100 ("T100") well location in Egypt.

Stages one through three, which are located across the heavily fractured and more permeable section of the well, received a concentrated acid stimulation while stages four through twelve were mechanically fracture stimulated with proppant.

At least 50 tonnes of sand were used per stage in the mechanically propped fracture stages with over 1,000,000 pounds successfully pumped across the 308-metre lateral section.

The fracture equipment has been moved off location, and a coiled tubing unit is in the process of drilling out the ball seats used to separate the fracture stages that will be followed with the flow back operations in the next several days.

TAG Oil's technical team is assuming approximately 7-10 days of flow back before it expects to see consistent clean oil flows. Stabilized flow rates are expected approximately 10 days after consistent oil rates are achieved. Accordingly, the Company expects to be able to release flow rates on the T100 well at some point during the month of May.
