TAG Oil increases drilling activity in Badr field

TAG Oil Ltd. has put well BED 1-7 online in Badr oil field (BED-1) in the Western Desert of Egypt and will spud a horizontal well in July.

TAG Oil successfully reentered vertical well BED 1-7 on May 10 and chose it for its first recompletion and evaluation operations in BED-1 (OGJ Online, May 10, 2023).  

Since initial flowback of the BED 1-7 on Apr. 23, 2023, the well started unloading completion fluid from the fracture stimulation and formation oil under natural flow. The company temporarily shut-in the well to install production tubing and a down-hole electric submersible pump (ESP).

The well started production at 150-200 bbl fluid/d on May 19 from the Abu-Roash “F” (ARF) reservoir and continued to unload 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 2 weeks, down-hole pump intake pressure and production stabilized at an average rate of 140 bo/d with about 5% water content at a constant ESP pump speed and wellhead choke of 10/64 in. The company intends to maintain the same pump speed and choke size to monitor the well’s performance for the next 30-60 days. Cumulative oil production from the well to date is over 4,000 bbl of 23° API oil.

The well test achieved TAG Oil’s objectives, including the diagnostic fracture injection test 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.

TAG Oil secured a 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 the well 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 in the ARF reservoir. Information will be collected during drilling 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.
