MONITORING BOREHOLES CONSTRUCTION REPORT KM8 WELL, KIRBY MISPERTON A WELLSITE, NORTH YORKSHIRE

1 INTRODUCTION

Third Energy UK Gas Limited (Third Energy) is proposing to hydraulically fracture an existing hydrocarbon production well (KM8) at Kirby Misperton A Wellsite, North Yorkshire (“the KMA wellsite”).

To comply with the Environment Agency requirement to establish a water quality baseline ahead of the proposed hydraulic fracturing, five (5) monitoring boreholes were constructed at the KMA wellsite in December 2015, as follows:

• Three (3) shallow boreholes (BHA, BHB, BHC) targeting the superficial deposits/weathered zone of the Kimmeridge Clay Formation.

• One (1) intermediate borehole (BHD) targeting the un-weathered Kimmeridge Clay Formation/Ampthill Clay Formation (Ancholme Group).

• One (1) deep borehole (BHE) targeting the top ~30m of the Corallian Group.

A mining waste and groundwater activity permit (Ref. EPR/DB3002HE) was issued by the Environment Agency for the hydraulic fracturing operation in April 2016. The permit includes five pre-operational measures (PO1 – PO5). PO4 states:

Prior to the operation of the regulated facility the operator shall provide a written report that provides the following information for each groundwater monitoring borehole installed:

(a) casing/linings (length, diameter, material, type of grout or filter media and whether slotted or plain);

(b) depths and diameters of unlined sections;

(d) details of strata encountered during drilling;

(e) reference levels for the individual criteria specified in 4(a) to (c) above in metres above ordnance datum;

(f) a location plan at a suitable scale showing the boreholes in relation to the point of discharge;

(g) national grid references of the boreholes in the form AB 12345 67890

any other information obtained from the boreholes relevant to the interpretation of water sample analysis.

This report has been prepared by Envireau Water to fulfil the requirements of PO4 and is intended to be submitted to the Environment Agency prior to the hydraulic fracturing operation.

Please note that this report does not provide a description of the regional geology and hydrogeology, which is covered in detail in the Hydrogeological Risk Assessment that was prepared by Envireau Water in May 2015 [Ref. 1].

2 KMA WELLSITE MONITORING BOREHOLES.

2.1 Location

The location of the five wellsite monitoring boreholes is presented on a site layout plan on Figure 1. Also shown on Figure 1 is the location of the point of discharge. Table 1 below presents the surveyed borehole coordinates including ground and wellhead elevations to Ordnance Datum. The surveying map is presented in Appendix A.

2.2 Construction Details

The monitoring boreholes were constructed by Magpie Environmental Drilling Ltd, with Envireau Water providing technical support when required. The construction of the monitoring boreholes commenced on the 27 November 2015 and was completed on the 9 December 2015.

The final depth of all the boreholes was based on the observed geological sequence and was agreed with the Environment Agency prior to completion.

The driller’s logs are provided in Appendix B. Summary construction details are presented in Table 2 below together with records of groundwater ingress (water strikes) during construction and groundwater levels on completion.

2.3 Geological Sequence

The geological sequence has been determined by Envireau Water based on the logging of recovered drilling returns. The geology encountered is summarised in Table 3 below and presented on the borehole construction diagrams on Figures 2, 3 and 4.

The geological sequence at the KMA wellsite consists of made ground / top soil up to 4 meters in depth, overlying mudstone and clay of the Kimmeridge Clay Formation/Ampthill Clay Formation (Ancholme Group) to a depth of approximately 177mbgl. The Ancholme Group is underlain by oolitic limestone of the Corallian Group. The transition between the Ancholme Group and the Corallian Group is not abrupt and appears to occur over a depth between 177mgl and 190mbgl.

2.4 Borehole Development

Following construction, the monitoring boreholes were airlifted by the drilling company until the water discharging from the boreholes was observed to be clear. Envireau Water also installed temporary submersible pumping equipment to perform clearance pumping on the 17 and 22 December 2015, again until the water was observed to be clear. The boreholes were then left to stand over the Christmas 2015 period. The Corallian borehole was airlifted a second time on the 24th of February 2016 because drilling mud was observed during a sampling trial on the 21st of January 2016.

2.5 Groundwater Levels on Completion

Groundwater levels observed during clearance pumping activities are presented in Table 2. The results suggest that groundwater levels in the Corallian Group are higher than in the overlying Ancholme Group.

2.6 Field Water Chemistry

Water samples were collected on the 22nd/23rd and 31st March 2016 using low flow pneumatic bladder pumps after the boreholes were airlifted clean. The water samples were analysed using IN-SITU field chemistry probes and the data summarised in Table 4 below.
