TAG Oil 实现生产目标,确保埃及油井的钻机安全

世界石油工作人员 2023 年 6 月 19 日

(WO) — TAG 石油有限公司提供了埃及西部沙漠 BED-1 油田的最新运营情况。

BED 1-7井产量

自2023年4月23日BED 1-7井首次返排以来,该井开始在自然流动下将压裂增产液和地层油排至地面完井液。该公司暂时关井以安装生产油管和井下电潜泵(“ESP”)。

BED 1-7 井于 2023 年 5 月 19 日开始生产,使用 ESP 泵从 Abu-Roash“F”(“ARF”)油藏以每天 150 至 200 桶流体的速度开始生产,并继续卸载剩余的压裂液第一周地层油逐渐增加。泵速和表面阻流器的调整是为了实现稳定的生产率。

过去两周,在 ESP 泵速恒定且井口节流器为 10/64" 的情况下,井下泵入口压力和产量稳定在平均 140 bopd,含水量约 5%。公司打算保持相同水平泵速和节流阀尺寸,以监测未来 30 至 60 天内油井的性能。迄今为止,该井的累计石油产量超过 4,000 桶 23 度 API 石油。

BED 1-7 直井测试的表现实现了公司的该井目标,包括用于指示储层参数的诊断性压裂注入测试 (DFIT) 压力泄漏、来自 ARF 的流体样本、成功完成了大型ARF 的单级压裂处理以及增产井的流入性能测试。

公司还大量了解了埃及西部沙漠材料和服务的可用性、质量和交付情况,这对于实施新水平井以及与当地合作伙伴合作确保现场设备和人员的通行非常重要行动并为 BED-1 领域未来的行动制定时间表。

TAG石油T100水平井

该公司成功为第一口水平井 BED4-T100(“T100”)找到了合适的钻机,该钻机采用 ARF 地层的多级压裂增产完井设计。该钻机将于七月中旬从西部沙漠的当前位置调动起来,并计划不久后开始钻探。

该井设计包括用于潜在取芯、裸眼测井、地层成像、压力测量和流体取样的垂直先导评估井,然后是下部垂直先导孔的水泥塞回以及建造和横向水平部分的造斜器钻井。 ARF 油藏中的 T100 新井。

将在钻井过程中收集信息,包括录井和钻屑,以评估横向储层质量,这些信息将与该地区已完成的地质力学特性和 3D 地震解释工作结合使用,以进行设计完井。

TAG Oil achieves production goals, secures drilling rig for Egyptian well

World Oil Staff June 19, 2023

(WO) – TAG Oil Ltd. provided an operations update at the BED-1 Field in the Western Desert, Egypt.

BED 1-7 well production

Since initial flowback of the BED 1-7 well on April 23, 2023, the well started by unloading to surface completion fluid from the fracture stimulation and formation oil under natural flow. The Company temporarily shut-in the well to install production tubing and down-hole Electric Submersible Pump ("ESP").

The BED 1-7 well started production on May 19, 2023, from the Abu-Roash "F" ("ARF") reservoir with the ESP pump at rates of 150 to 200 barrels of fluid per day and continued to unload remaining fracture fluid with gradual increase of formation oil over the first week. Pump speeds and surface choke adjustments were made to achieve a stabilized rate of production.

Over the past two weeks, down-hole pump intake pressure and production stabilized at an average rate of 140 bopd with about 5% water content at a constant ESP pump speed and wellhead choke of 10/64". The Company intends to maintain the same pump speed and choke size to monitor the well's performance for the next 30 to 60 days. Cumulative oil production from the well to date is over 4,000 bbl of 23-degree API Oil.

The performance of the BED 1-7 vertical well test has achieved the company's objectives for the well, including the Diagnostic Fracture Injection Test (DFIT) pressure leak-off for indications of reservoir parameters, fluid samples from the ARF, successful completion of a large single-stage fracture treatment on the ARF, and inflow performance testing of the stimulated well.

The Company also learned a significant amount about the availability, quality and delivery of materials and services in the Western Desert of Egypt, which will be important for implementation of the new horizontal well and working with local partners to ensure access for equipment and personnel in field operations and establishing timeline for future operations in the BED-1 Field.

TAG Oil T100 horizontal well

The Company was successful in securing a suitable drilling rig for the first horizontal well, BED4-T100 ("T100"), designed with a multi-stage fracture stimulation completion of the ARF formation. The rig will be mobilized from its current location in the Western Desert by mid-July and is scheduled to commence drilling shortly after.

The well design includes a vertical pilot assessment well for potential coring, open-hole logging, formation imaging, pressure measurement and fluid sampling, followed by cement plug-back of lower vertical pilot hole and whip-stock drilling of build and lateral horizontal sections of the T100 new well in the ARF reservoir.

Information will be collected during the drilling of the well including mud logging and drill cuttings to assess the reservoir quality across the lateral, which will be used in conjunction with the work completed on the geo-mechanical properties and 3D seismic interpretation in the area to design the well completion.
